The search looks for S3 bucket events related to bucket policies, website hosting configuration, and bucket deletion. The results are stored in a lookup KVStore named decommissioned_buckets which tracks the history of deleted buckets that were previously exposed to the public. known_false_positives: Some buckets may be intentionally made public for legitimate business purposes before being decommissioned. Review the policy_details and website_details fields to understand the nature of the public access that was configured. references: -- https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-control-block-public-access.html -- https://labs.watchtowr.com/8-million-requests-later-we-made-the-solarwinds-supply-chain-attack-look-amateur/ -- https://aws.amazon.com/premiumsupport/knowledge-center/secure-s3-resources/ -tags: - analytic_story: - - AWS S3 Bucket Security Monitoring - - Suspicious AWS S3 Activities - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - detections: - - Detect DNS Query to Decommissioned S3 Bucket - - Detect Web Access to Decommissioned S3 Bucket - security_domain: audit -deployment: - scheduling: + - https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-control-block-public-access.html + - https://labs.watchtowr.com/8-million-requests-later-we-made-the-solarwinds-supply-chain-attack-look-amateur/ + - https://aws.amazon.com/premiumsupport/knowledge-center/secure-s3-resources/ +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +security_domain: audit +custom_schedule: cron_schedule: 0 2 * * 0 earliest_time: -30d@d latest_time: -1d@d diff --git a/baselines/baseline_of_s3_bucket_deletion_activity_by_arn.yml b/baselines/baseline_of_s3_bucket_deletion_activity_by_arn.yml index 6cc0e7862c8..089fb6f795e 100644 --- a/baselines/baseline_of_s3_bucket_deletion_activity_by_arn.yml +++ b/baselines/baseline_of_s3_bucket_deletion_activity_by_arn.yml @@ -1,31 +1,18 @@ name: Baseline of S3 Bucket deletion activity by ARN id: 841b102c-8866-494b-a704-87b674fe9b09 -version: 2 -date: '2026-01-14' +version: 3 +creation_date: '2020-04-29' +modification_date: '2026-05-13' author: Bhavin Patel, Splunk -type: Baseline status: production -description: This search establishes, on a per-hour basis, the average and standard - deviation for the number of API calls related to deleting an S3 bucket by each user. - Also recorded is the number of data points for each user.

The issue impacts all versions of CrushFTP up to 10.7.1 and 11.1.0 on all supported platforms. It is highly recommended to apply patches immediately to prevent unauthorized access to the system and avoid potential data compromises. The search specifically looks for patterns in the raw log data that match the exploitation attempts, including READ or WRITE actions, and extracts relevant information such as the protocol, session ID, user, IP address, HTTP method, and the URI queried.

Ensure that audit logging is enabled in your Kubernetes cluster. Kubernetes audit logs provide a record of the requests made to the Kubernetes API server, which is crucial for monitoring and detecting suspicious activities. Configure the audit policy in Kubernetes to determine what kind of activities are logged. This is done by creating an Audit Policy and providing it to the API server. Use the Splunk OpenTelemetry Collector for Kubernetes to collect the logs. This doc will describe how to collect the audit log file https://github.com/signalfx/splunk-otel-collector-chart/blob/main/docs/migration-from-sck.md.

To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives: A certain amount of false positives are likely with this detection.

It leverages Sysmon EventCode 10, filtering for specific access permissions (0x1010 and 0x1410) on the lsass.exe process.

This search uses an input macro named `sysmon`. We strongly recommend that you specify your environment-specific configurations (index, source, sourcetype, etc.) for Windows Sysmon logs. Replace the macro definition with configurations for your Splunk environment. The search also uses a post-filter macro designed to filter out known false positives. known_false_positives: The activity may be legitimate. Other tools can access lsass for legitimate reasons, and it's possible this event could be generated in those cases. In these cases, false positives should be fairly obvious and you may need to tweak the search to eliminate noise. -references: [] +references: + - https://www.microsoft.com/en-us/security/blog/2022/10/05/detecting-and-preventing-lsass-credential-dumping-attacks/ + -

These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the file path, file name, and the user that created the file. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Registry` node of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. The "exceptions" macro leverages both an Assets and Identities lookup, as well as a KVStore collection called "remote_software_exceptions" that lets you track and maintain device-based exceptions for this set of detections. known_false_positives: Known or approved applications used by the organization or usage of built-in functions. Known false positives can be added to the remote_access_software_usage_exception.csv lookup to globally suppress these situations across all remote access content references: @@ -28,44 +29,46 @@ drilldown_searches: search: '| from datamodel:Endpoint.Registry| search dest=$dest$ registry_path=$registry_path$' earliest_offset: $info_min_time$ latest_offset: $info_max_time$ -rba: -

To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

This behavior is consistent with abuse of userns,-carrying AppArmor profiles to bypass Ubuntu's unprivileged user namespace restrictions as seen in the CVE-2026-46331 privilege escalation exploit. The analytic flags execution when the target command following -- is invoked via a relative path, resolves outside standard trusted install directories for these applications, or shares the same binary name as the calling parent process. Adversaries and red teams may abuse this technique to escalate privileges by tricking aa-exec into granting a namespace-creation capability to an arbitrary binary rather than the trusted application the profile was written for. +data_source: + - Sysmon for Linux EventID 1 +search: |- + | tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime + from datamodel=Endpoint.Processes where + Processes.process_name="*aa-exec" + AND Processes.process="* -p *" + AND Processes.process="*--*" + AND Processes.process IN ("*trinity*","*chrome*","*flatpak*") + AND NOT Processes.process IN ("/user*","/opt*","/snap*","/var/lib/flatpak*") + by Processes.action Processes.dest Processes.original_file_name Processes.parent_process Processes.parent_process_exec + Processes.parent_process_guid Processes.parent_process_id Processes.parent_process_name Processes.parent_process_path + Processes.process Processes.process_exec Processes.process_guid Processes.process_hash Processes.process_id + Processes.process_integrity_level Processes.process_name Processes.process_path Processes.user Processes.user_id + Processes.vendor_product + | `drop_dm_object_name(Processes)` + | `security_content_ctime(firstTime)` + | `security_content_ctime(lastTime)` + | `linux_apparmor_bypass_via_aaexec_filter` +how_to_implement: The detection is based on data that originates from Endpoint Detection and Response (EDR) agents.

These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

Legitimate privilege elevation mechanisms such as sudo, su, and pkexec authenticate through PAM and generate these audit records tied to the session ID before granting elevated privileges. The absence of a matching successful PAM event alongside an effective UID change to root is anomalous and may indicate exploitation of a setuid binary, a kernel vulnerability, or another mechanism used to escalate privileges outside the normal authentication flow. +data_source: + - Linux Auditd Execve +search: >- + `linux_auditd` ( + (type=SYSCALL syscall="59" uid!="0" euid="0") + OR + (type IN ("USER_AUTH","USER_ACCT","CRED_ACQ") res="success") + ) + | eval is_suspicious_exec=if(type="SYSCALL" AND syscall="59" AND uid!="0" AND euid="0", 1, 0) + | eval is_successful_auth=if(type IN ("USER_AUTH","USER_ACCT","CRED_ACQ") AND res="success", 1, 0) + | stats + count(eval(is_suspicious_exec=1)) as exec_count + max(eval(if(is_suspicious_exec=1, _time, null()))) as lastTime + max(is_successful_auth) as has_successful_auth + min(eval(if(is_suspicious_exec=1, _time, null()))) as firstTime + values(eval(if(is_suspicious_exec=1, comm, null()))) as process_name + values(eval(if(is_suspicious_exec=1, euid, null()))) as euid + values(eval(if(is_suspicious_exec=1, exe, null()))) as process_path + values(eval(if(is_suspicious_exec=1, pid, null()))) as pid + values(eval(if(is_suspicious_exec=1, ppid, null()))) as ppid + values(eval(if(is_suspicious_exec=1, uid, null()))) as uid + by host ses + | where exec_count > 0 AND has_successful_auth != 1 + | rename host as dest, ses as session_id + | `security_content_ctime(firstTime)` + | `security_content_ctime(lastTime)` + | `linux_auditd_possible_setuid_execve_privesc_filter` +how_to_implement: To implement this detection, the process begins by ingesting auditd data, that consist SYSCALL, TYPE, EXECVE and PROCTITLE events, which captures command-line executions and process details on Unix/Linux systems. These logs should be ingested and processed using Splunk Add-on for Unix and Linux (https://splunkbase.splunk.com/app/833), which is essential for correctly parsing and categorizing the data. The next step involves normalizing the field names to match the field names set by the Splunk Common Information Model (CIM) to ensure consistency across different data sources and enhance the efficiency of data modeling. This approach enables effective monitoring and detection of linux endpoints where auditd is deployed. +known_false_positives: Processes with an unset audit session, such as cron jobs, that legitimately drop and reacquire root privileges outside of PAM, may trigger this detection and require filtering. +references: + -

This activity is significant because it is commonly used by malware such as RATs, bots, or Trojans to evade detection by allowing threats to pass through the Windows Defender antivirus engine.

These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives: Disaster recovery events. @@ -22,33 +23,36 @@ drilldown_searches: search: '| from datamodel Risk.All_Risk | search normalized_risk_object IN ("$user$", "$dest$") | stats count min(_time) as firstTime max(_time) as lastTime values(search_name) as "Search Name" values(risk_message) as "Risk Message" values(analyticstories) as "Analytic Stories" values(annotations._all) as "Annotations" values(annotations.mitre_attack.mitre_tactic) as "ATT&CK Tactics" by normalized_risk_object | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)`' earliest_offset: 7d latest_offset: "0" -rba: - message: DSRM Account Changes Initiated on $dest$ by $user$ - risk_objects: - - field: user - type: user - score: 50 +finding: + title: DSRM Account Changes Initiated on $dest$ by $user$ + entity: + field: user + type: user + score: 50 +intermediate_findings: + entities: - field: dest type: system score: 50 - threat_objects: [] -tags: - analytic_story: - - Sneaky Active Directory Persistence Tricks - - Windows Registry Abuse - - Windows Persistence Techniques - - Scattered Lapsus$ Hunters - asset_type: Endpoint - mitre_attack_id: - - T1098 - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - security_domain: endpoint + message: DSRM Account Changes Initiated on $dest$ by $user$ +analytic_story: + - Sneaky Active Directory Persistence Tricks + - Windows Registry Abuse + - Windows Persistence Techniques + - Scattered Lapsus$ Hunters +asset_type: Endpoint +mitre_attack_id: + - T1098 +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +category: endpoint +security_domain: endpoint tests: - name: True Positive Test attack_data: - data: https://media.githubusercontent.com/media/splunk/attack_data/master/datasets/attack_techniques/T1098/dsrm_account/windows-sysmon.log source: XmlWinEventLog:Microsoft-Windows-Sysmon/Operational sourcetype: XmlWinEventLog + test_type: unit diff --git a/detections/endpoint/windows_ad_dsrm_password_reset.yml b/detections/endpoint/windows_ad_dsrm_password_reset.yml index df1f02c1fd9..7ad5873bbb8 100644 --- a/detections/endpoint/windows_ad_dsrm_password_reset.yml +++ b/detections/endpoint/windows_ad_dsrm_password_reset.yml @@ -1,13 +1,14 @@ name: Windows AD DSRM Password Reset id: d1ab841c-36a6-46cf-b50f-b2b04b31182a -version: 9 -date: '2026-04-15' +version: 10 +creation_date: '2022-09-08' +modification_date: '2026-10-02' author: Dean Luxton -type: TTP status: production +type: TTP +description: The following analytic detects attempts to reset the Directory Services Restore Mode (DSRM) administrator password on a Domain Controller.

These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives: False positives may be limited to source control applications and may be required to be filtered out. references: -

It tracks both connection attempts (EventID 4648) and successful logons (EventID 4624) associated with PSWA, providing a comprehensive view of access patterns. The analytic identifies PSWA's operational status, host servers, processes, and connection metrics. It highlights unique target accounts, domains accessed, and verifies logon types. This information is crucial for detecting potential misuse, such as lateral movement, brute force attempts, or unusual access patterns. By offering insights into PSWA activity, it enables security teams to quickly assess and investigate potential security incidents involving this powerful administrative tool. +data_source: + - Windows Event Log Security 4648 search: '`wineventlog_security` (EventCode=4648 OR EventCode=4624 OR EventCode=4625) SubjectUserName="pswa_pool" | fields EventCode, SubjectUserName, TargetUserName, Computer, TargetDomainName, ProcessName, LogonType | rename Computer as dest | stats count(eval(EventCode=4648)) as "Connection Attempts", count(eval(EventCode=4624)) as "Successful Logons", count(eval(EventCode=4625)) as "Unsuccessful Logons", dc(TargetUserName) as "Unique Target Accounts", values(dest) as "PSWA Host", dc(TargetDomainName) as "Unique Target Domains", values(ProcessName) as "PSWA Process", values(TargetUserName) as "Target Users List", values(TargetServerName) as "Target Servers List", values(LogonType) as "Logon Types" | eval PSWA_Running = "Yes", "PSWA Process" = mvindex(split(mvindex("PSWA Process", 0), "\\"), -1) | fields PSWA_Running, "PSWA Host", "PSWA Process", "Connection Attempts", "Successful Logons","Unsuccessful Logons", "Unique Target Accounts", "Unique Target Domains", "Target Users List","Target Servers List", "Logon Types" | `security_content_ctime(firstTime)` |`security_content_ctime(lastTime)` | `windows_identify_powershell_web_access_iis_pool_filter`' how_to_implement: To successfully implement this search, you need to be ingesting Windows Security Event logs, specifically Event ID 4648 (A logon was attempted using explicit credentials). Ensure that your Windows systems are configured to audit logon events and that these logs are being forwarded to your SIEM or log management solution. You may need to enable advanced audit policy settings in Windows to capture these events. Additionally, make sure that your environment is set up to capture the necessary fields such as SubjectUserName, TargetUserName, Computer, TargetServerName, and ProcessName from these events. If you're using Splunk, ensure that you have the appropriate Windows TA installed and configured to collect these security logs. known_false_positives: False positives may occur if legitimate PSWA processes are used for administrative tasks. Careful review of the logs is recommended to distinguish between legitimate and malicious activity. references: - https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-241a - https://gist.github.com/MHaggis/7e67b659af9148fa593cf2402edebb41 -tags: - analytic_story: - - CISA AA24-241A - asset_type: Endpoint - mitre_attack_id: - - T1190 - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - security_domain: endpoint - cve: [] +analytic_story: + - CISA AA24-241A +asset_type: Endpoint +mitre_attack_id: + - T1190 +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +category: endpoint +security_domain: endpoint tests: - name: True Positive Test attack_data: - data: https://media.githubusercontent.com/media/splunk/attack_data/master/datasets/attack_techniques/T1190/pswa/4648_4624_pswa_pool.log sourcetype: XmlWinEventLog source: XmlWinEventLog:Security + test_type: unit diff --git a/detections/endpoint/windows_identify_protocol_handlers.yml b/detections/endpoint/windows_identify_protocol_handlers.yml index 02c39f8db53..fc2a6a88253 100644 --- a/detections/endpoint/windows_identify_protocol_handlers.yml +++ b/detections/endpoint/windows_identify_protocol_handlers.yml @@ -1,7 +1,8 @@ name: Windows Identify Protocol Handlers id: bd5c311e-a6ea-48ae-a289-19a3398e3648 -version: 9 -date: '2026-02-25' +version: 11 +creation_date: '2022-07-12' +modification_date: '2026-10-02' author: Michael Haag, Splunk status: production type: Hunting @@ -22,7 +23,7 @@ search: |- | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)` | `drop_dm_object_name(Processes)` - | lookup windows_protocol_handlers handler AS process OUTPUT handler ishandler + | lookup local=t windows_protocol_handlers handler AS process OUTPUT handler ishandler | where ishandler="TRUE" | `windows_identify_protocol_handlers_filter` how_to_implement: The detection is based on data that originates from Endpoint Detection and Response (EDR) agents.

These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` and `Filesystem` nodes of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives: This analytic may flag instances where DLLs are loaded by user mode programs for entirely legitimate and benign purposes. It is important for users to be aware that false positives are not only possible but likely, and that careful tuning of this analytic is necessary to distinguish between malicious activity and normal, everyday operations of applications. This may involve adjusting thresholds, whitelisting known good software, or incorporating additional context from other security tools and logs to reduce the rate of false positives. references: @@ -25,33 +26,35 @@ drilldown_searches: search: '| from datamodel Risk.All_Risk | search normalized_risk_object IN ("$dest$", "$user$") | stats count min(_time) as firstTime max(_time) as lastTime values(search_name) as "Search Name" values(risk_message) as "Risk Message" values(analyticstories) as "Analytic Stories" values(annotations._all) as "Annotations" values(annotations.mitre_attack.mitre_tactic) as "ATT&CK Tactics" by normalized_risk_object | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)`' earliest_offset: 7d latest_offset: "0" -rba: - message: The file [$file_name$] was written to an unusual location on [$dest$]. - risk_objects: +intermediate_findings: + entities: - field: dest type: system score: 20 + message: The file [$file_name$] was written to an unusual location on [$dest$]. - field: user type: user score: 20 - threat_objects: - - field: file_name - type: file_name -tags: - analytic_story: - - Windows Defense Evasion Tactics - - Living Off The Land - asset_type: Endpoint - mitre_attack_id: - - T1574.001 - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - security_domain: endpoint + message: The file [$file_name$] was written to an unusual location on [$dest$]. +threat_objects: + - field: file_name + type: file_name +analytic_story: + - Windows Defense Evasion Tactics + - Living Off The Land +asset_type: Endpoint +mitre_attack_id: + - T1574.001 +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +category: endpoint +security_domain: endpoint tests: - name: True Positive Test attack_data: - data: https://media.githubusercontent.com/media/splunk/attack_data/master/datasets/attack_techniques/T1574.002/hijacklibs/hijacklibs_sysmon.log source: XmlWinEventLog:Microsoft-Windows-Sysmon/Operational sourcetype: XmlWinEventLog + test_type: unit diff --git a/detections/endpoint/windows_known_abused_dll_loaded_suspiciously.yml b/detections/endpoint/windows_known_abused_dll_loaded_suspiciously.yml index 8c2edf92d4d..cdede1c4363 100644 --- a/detections/endpoint/windows_known_abused_dll_loaded_suspiciously.yml +++ b/detections/endpoint/windows_known_abused_dll_loaded_suspiciously.yml @@ -1,16 +1,128 @@ name: Windows Known Abused DLL Loaded Suspiciously id: dd6d1f16-adc0-4e87-9c34-06189516b803 -version: 11 -date: '2026-04-15' +version: 13 +creation_date: '2024-04-06' +modification_date: '2026-09-22' author: Steven Dick status: production type: TTP -description: The following analytic detects when DLLs with known abuse history are loaded from an unusual location.

Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. +known_false_positives: |- + No false positives have been identified at this time. +references: + -

To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

If confirmed malicious, this behavior could allow attackers to execute arbitrary code, escalate privileges, or maintain persistence within the environment, posing a significant security risk. +data_source: + - Sysmon EventID 11 search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime from datamodel=Endpoint.Filesystem where Filesystem.file_name=*.txt Filesystem.file_path IN ("*\\Windows\\Tasks\\*", "*\\Windows\\Temp\\*", "*\\Windows\\tracing\\*", "*\\Windows\\PLA\\Reports\\*", "*\\Windows\\PLA\\Rules\\*", "*\\Windows\\PLA\\Templates\\*", "*\\Windows\\PLA\\Reports\\en-US\\*", "*\\Windows\\PLA\\Rules\\en-US\\*", "*\\Windows\\Registration\\CRMLog\\*", "*\\Windows\\System32\\Tasks\\*", "*\\Windows\\System32\\Com\\dmp\\*", "*\\Windows\\System32\\LogFiles\\WMI\\*", "*\\Windows\\System32\\Microsoft\\Crypto\\RSA\\MachineKeys\\*", "*\\Windows\\System32\\spool\\PRINTERS\\*", "*\\Windows\\System32\\spool\\SERVERS\\*", "*\\Windows\\System32\\spool\\drivers\\color\\*", "*\\Windows\\System32\\Tasks\\Microsoft\\Windows\\RemoteApp and Desktop Connections Update\\*", "*\\Windows\\SysWOW64\\Tasks\\*", "*\\Windows\\SysWOW64\\Com\\dmp\\*", "*\\Windows\\SysWOW64\\Tasks\\Microsoft\\Windows\\PLA\\*", "*\\Windows\\SysWOW64\\Tasks\\Microsoft\\Windows\\RemoteApp and Desktop Connections Update\\*", "*\\Windows\\SysWOW64\\Tasks\\Microsoft\\Windows\\PLA\\System\\*") by Filesystem.dest, Filesystem.user, Filesystem.file_name Filesystem.file_path | `drop_dm_object_name("Filesystem")` | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)` | `windows_process_writing_file_to_world_writable_path_filter`' how_to_implement: The detection is based on data that originates from Endpoint Detection and Response (EDR) agents. These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the file creation event, process name, file path and, file name. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Filesystem` node of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives: False positives may occur if legitimate software writes to these paths. Modify the search to include additional file name extensions. To enhance it further, adding a join on Processes.process_name may assist with restricting the analytic to specific process names. Investigate the process and file to determine if it is malicious. references: - https://research.splunk.com/endpoint/efbcf8ee-bc75-47f1-8985-a5c638c4faf0/ -tags: - analytic_story: - - APT29 Diplomatic Deceptions with WINELOADER -

These agents are designed to provide security-related telemetry from the endpoints where the agent is installed. To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model. Use the Splunk Common Information Model (CIM) to normalize the field names and speed up the data modeling process. known_false_positives: Note that false positives may occur, and filtering may be necessary, especially when it comes to remote service creation by administrators or software management utilities. references: -

To implement this search, you must ingest logs that contain the process GUID, process name, and parent process. Additionally, you must ingest complete command-line executions. These logs must be processed using the appropriate Splunk Technology Add-ons that are specific to the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint` data model.

Monitoring for these files helps to quickly identify malicious screen capture attempts, allowing security teams to respond and mitigate potential information exposure before sensitive data is compromised. +data_source: + - Sysmon EventID 11 search: '|tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime FROM datamodel=Endpoint.Filesystem where Filesystem.file_name IN ("screenshot.png", "screenshot.jpg","screenshot.bmp") Filesystem.file_path = "*\\temp\\*" by Filesystem.action Filesystem.dest Filesystem.file_access_time Filesystem.file_create_time Filesystem.file_hash Filesystem.file_modify_time Filesystem.file_name Filesystem.file_path Filesystem.file_acl Filesystem.file_size Filesystem.process_guid Filesystem.process_id Filesystem.user Filesystem.vendor_product | `drop_dm_object_name(Filesystem)` | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)` | `windows_screen_capture_in_temp_folder_filter`' how_to_implement: To successfully implement this search you need to be ingesting information on process that include the name of the process responsible for the changes from your endpoints into the `Endpoint` datamodel in the `Processes` node.

Hunting queries are designed to be executed manual during threat hunting. data_source: [] -search: '`amazon_security_lake` api.operation=CreateAccessKey http_request.user_agent!=console.amazonaws.com - api.response.error=null | rename unmapped{}.key as unmapped_key , unmapped{}.value - as unmapped_value | eval keyjoin=mvzip(unmapped_key,unmapped_value) | mvexpand keyjoin - | rex field=keyjoin "^(?[^,]+),(?.*)$" | eval {key} = value | search - responseElements.accessKey.userName = * | rename identity.user.name as identity_user_name, - responseElements.accessKey.userName as responseElements_accessKey_userName | eval - match=if(identity_user_name=responseElements_accessKey_userName,1,0) | search match=0 - | rename identity_user_name as identity.user.name , responseElements_accessKey_userName - as responseElements.accessKey.userName | stats count min(_time) as firstTime max(_time) - as lastTime by responseElements.accessKey.userName api.operation api.service.name - identity.user.account_uid identity.user.credential_uid identity.user.name identity.user.type - identity.user.uid identity.user.uuid http_request.user_agent src_endpoint.ip | `security_content_ctime(firstTime)` - | `security_content_ctime(lastTime)` |`asl_aws_createaccesskey_filter`' -how_to_implement: You must install Splunk Add-On for AWS Version v7.0.0 (https://splunkbase.splunk.com/app/1876) - that includes includes a merge of all the capabilities of the Splunk Add-on for - Amazon Security Lake.

This activity is significant because exporting these keys can allow attackers to obtain hashed credentials, which they may attempt to crack offline. If confirmed malicious, this could lead to unauthorized access to sensitive accounts, enabling further compromise and lateral movement within the network. data_source: -- Sysmon EventID 1 -- Windows Event Log Security 4688 -- CrowdStrike ProcessRollup2 -search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) - as lastTime from datamodel=Endpoint.Processes where Processes.process_name=reg* - OR Processes.process_name=cmd* Processes.process=*save* (Processes.process=*HKEY_LOCAL_MACHINE\\Security* - OR Processes.process=*HKEY_LOCAL_MACHINE\\SAM* OR Processes.process=*HKEY_LOCAL_MACHINE\\System* - OR Processes.process=*HKLM\\Security* OR Processes.process=*HKLM\\System* OR Processes.process=*HKLM\\SAM*) - by Processes.dest Processes.user Processes.parent_process Processes.parent_process_name Processes.process_name - Processes.original_file_name Processes.process Processes.process_id Processes.parent_process_id - | `drop_dm_object_name(Processes)` | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)` - | `attempted_credential_dump_from_registry_via_reg_exe_filter`' -how_to_implement: The detection is based on data that originates from Endpoint Detection - and Response (EDR) agents.

If confirmed malicious, this behavior could allow attackers to execute arbitrary code, potentially leading to data exfiltration, system compromise, or further malware deployment. data_source: -- Sysmon EventID 1 -- Windows Event Log Security 4688 -- CrowdStrike ProcessRollup2 -search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) - as lastTime from datamodel=Endpoint.Processes where Processes.parent_process_name - IN ("winword.exe","excel.exe","powerpnt.exe","mspub.exe","visio.exe", "onenote.exe","onenotem.exe", - "msaccess.exe","Graph.exe","winproj.exe") `process_mshta` by Processes.dest Processes.user - Processes.parent_process_name Processes.parent_process Processes.process_name Processes.original_file_name - Processes.process Processes.process_id Processes.parent_process_id | `drop_dm_object_name(Processes)` - | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)` | `office_product_spawning_mshta_filter`' -how_to_implement: The detection is based on data that originates from Endpoint Detection - and Response (EDR) agents.

This activity is significant as it may indicate an attempt to exploit protocol handlers to bypass security controls, even if macros are disabled. If confirmed malicious, this behavior could allow an attacker to execute arbitrary code, potentially leading to system compromise, data exfiltration, or further lateral movement within the network. data_source: -- Sysmon EventID 1 -- Windows Event Log Security 4688 -- CrowdStrike ProcessRollup2 -search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) - as lastTime from datamodel=Endpoint.Processes where Processes.parent_process_name - IN ("winword.exe","excel.exe","powerpnt.exe","outlook.exe","mspub.exe","visio.exe","onenote.exe","onenotem.exe","onenoteviewer.exe","onenoteim.exe","msaccess.exe") - Processes.process_name=msdt.exe by Processes.dest Processes.user Processes.parent_process_name - Processes.parent_process Processes.process_name Processes.original_file_name Processes.process - Processes.process_id Processes.parent_process_id | `drop_dm_object_name(Processes)` - | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)` | `windows_office_product_spawning_msdt_filter`' -how_to_implement: The detection is based on data that originates from Endpoint Detection - and Response (EDR) agents.

Detect and investigate tactics, techniques, and procedures around how attackers move laterally within the enterprise. Because lateral movement can expose the adversary to detection, it should be an important focus for security analysts." narrative: "Once attackers gain a foothold within an enterprise, they will seek to expand their accesses and leverage techniques that facilitate lateral movement. Attackers will often spend quite a bit of time and effort moving laterally. Because lateral movement renders an attacker the most vulnerable to detection, it's an excellent focus for detection and investigation. Indications of lateral movement can include the abuse of system utilities (such as `psexec.exe`), unauthorized use of remote desktop services, `file/admin$` shares, WMI, PowerShell, pass-the-hash, or the abuse of scheduled tasks. Organizations must be extra vigilant in detecting lateral movement techniques and look for suspicious activity in and around high-value strategic network assets, such as Active Directory, which are often considered the primary target or \"crown jewels\" to a persistent threat actor. An adversary can use lateral movement for multiple purposes, including remote execution of tools, pivoting to additional systems, obtaining access to specific information or files, access to additional credentials, exfiltrating data, or delivering a secondary effect. Adversaries may use legitimate credentials alongside inherent network and operating-system functionality to remotely connect to other systems and remain under the radar of network defenders. If there is evidence of lateral movement, it is imperative for analysts to collect evidence of the associated offending hosts. For example, an attacker might leverage host A to gain access to host B. From there, the attacker may try to move laterally to host C. In this example, the analyst should gather as much information as possible from all three hosts. It is also important to collect authentication logs for each host, to ensure that the offending accounts are well-documented. Analysts should account for all processes to ensure that the attackers did not install unauthorized software." references: -- https://www.fireeye.com/blog/executive-perspective/2015/08/malware_lateral_move.html + - https://www.fireeye.com/blog/executive-perspective/2015/08/malware_lateral_move.html tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + category: + - Adversary Tactics + product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud + usecase: Advanced Threat Detection +deprecation_info: + reason: Analytic Story deprecated as it no longer effectively identifies the intended malicious activity + removed_in_version: 5.2.0 + replacement_content: + - Active Directory Lateral Movement diff --git a/removed/stories/monitor_backup_solution.yml b/removed/stories/monitor_backup_solution.yml index 3b0074346d4..f26849664c2 100644 --- a/removed/stories/monitor_backup_solution.yml +++ b/removed/stories/monitor_backup_solution.yml @@ -1,26 +1,23 @@ name: Monitor Backup Solution id: abe807c7-1eb6-4304-ac32-6e7aacdb891d version: 1 -date: '2017-09-12' +creation_date: '2019-10-16' +modification_date: '2026-05-13' author: David Dorsey, Splunk status: removed -description: Address common concerns when monitoring your backup processes.

It commonly targets web browsers, messaging applications, cryptocurrency wallets, and local system files to gather stored credentials, cookies, autofill data, and session tokens. The malware often arrives via phishing emails, malicious attachments, cracked software, or drive-by downloads. Upon execution, ObjectivyStealer attempts to evade detection by operating from user profile or temporary directories and leveraging obfuscation to disguise its activity. Persistence is typically established through registry run keys or scheduled tasks, ensuring it remains active after system reboots. Detection is primarily achieved through endpoint monitoring of abnormal process behaviors, including unauthorized access to browser storage files, creation of unusual persistence artifacts, and suspicious outbound network connections. Analysts may also identify compressed or encrypted data being exfiltrated to remote command-and-control (C2) infrastructure. Timely detection is critical, as successful infections can result in credential theft, financial fraud, or additional malware deployment. narrative: During analysis, 0bj3ctivityStealer was observed executing from a user profile directory, indicating likely delivery via a phishing attachment or trojanized software. Once active, the malware began enumerating system information and targeting browser credential stores, extracting cookies, saved passwords, and session tokens. Telemetry revealed unauthorized access attempts to directories belonging to Chrome and Edge, followed by data compression and encryption routines. Network monitoring detected abnormal HTTPS POST requests containing encoded payloads destined for a known 0bj3ctivityStealer command-and-control server. Persistence was established through registry modifications, ensuring execution on system reboot. The malware continued to operate silently, exfiltrating harvested data at regular intervals. Correlation with threat intelligence confirmed the activity matched 0bj3ctivityStealer campaigns seen in underground marketplaces, where stolen data is often sold or leveraged for further compromise. Without intervention, this activity would likely lead to unauthorized account access, financial theft, and potential secondary infections from additional malware dropped post-exfiltration. references: -- https://www.trellix.com/blogs/research/a-deep-dive-into-obj3ctivitystealers-features/ -- https://www.esentire.com/blog/ande-loader-leads-to-0bj3ctivity-stealer-infection -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://www.trellix.com/blogs/research/a-deep-dive-into-obj3ctivitystealers-features/ + - https://www.esentire.com/blog/ande-loader-leads-to-0bj3ctivity-stealer-infection +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/3cx_supply_chain_attack.yml b/stories/3cx_supply_chain_attack.yml index 6829373141d..16457a9905d 100644 --- a/stories/3cx_supply_chain_attack.yml +++ b/stories/3cx_supply_chain_attack.yml @@ -1,26 +1,26 @@ name: 3CX Supply Chain Attack id: c4d7618c-73a7-4f7c-8071-060c36850785 -version: 1 -date: '2023-03-30' +version: 2 +creation_date: '2023-03-30' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: 'On March 29, 2023, CrowdStrike Falcon OverWatch observed unexpected malicious activity emanating from a legitimate, signed binary, 3CXDesktopApp, a softphone application from 3CX.

The multi-stage attack chain, which automatically quarantines trojanized installers, involves downloading ICO files with base64 data from GitHub and eventually leads to a 3rd stage infostealer DLL that is still under analysis. While the Mac installer remains unconfirmed as trojanized, ongoing investigations are also examining other potentially compromised applications, such as Chrome extensions. The threat actor behind the supply chain compromise, which started in February 2022, has used a code signing certificate to sign the trojanized binaries, but connections to existing threat clusters remain unclear. SentinelOne updated their IOCs on March 30th, 2023, with contributions from the research community and continues to monitor the situation for further developments. 3CX identified the vulnerability in the recent versions 18.12.407 and 18.12.416 for the desktop app. A new certificate for the app will also be produced.' references: - - https://www.sentinelone.com/blog/smoothoperator-ongoing-campaign-trojanizes-3cx-software-in-software-supply-chain-attack/ - - https://www.cisa.gov/news-events/alerts/2023/03/30/supply-chain-attack-against-3cxdesktopapp - - https://www.reddit.com/r/crowdstrike/comments/125r3uu/20230329_situational_awareness_crowdstrike/ - - https://www.3cx.com/community/threads/crowdstrike-endpoint-security-detection-re-3cx-desktop-app.119934/page-2#post-558898 - - https://www.3cx.com/community/threads/3cx-desktopapp-security-alert.119951/ - - https://www.elastic.co/security-labs/elastic-users-protected-from-suddenicon-supply-chain-attack - - https://www.volexity.com/blog/2023/03/30/3cx-supply-chain-compromise-leads-to-iconic-incident/ -tags: - cve: - - CVE-2023-29059 - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://www.sentinelone.com/blog/smoothoperator-ongoing-campaign-trojanizes-3cx-software-in-software-supply-chain-attack/ + - https://www.cisa.gov/news-events/alerts/2023/03/30/supply-chain-attack-against-3cxdesktopapp + - https://www.reddit.com/r/crowdstrike/comments/125r3uu/20230329_situational_awareness_crowdstrike/ + - https://www.3cx.com/community/threads/crowdstrike-endpoint-security-detection-re-3cx-desktop-app.119934/page-2#post-558898 + - https://www.3cx.com/community/threads/3cx-desktopapp-security-alert.119951/ + - https://www.elastic.co/security-labs/elastic-users-protected-from-suddenicon-supply-chain-attack + - https://www.volexity.com/blog/2023/03/30/3cx-supply-chain-compromise-leads-to-iconic-incident/ +cve: + - CVE-2023-29059 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/abnormal_kubernetes_behavior_using_splunk_infrastructure_monitoring.yml b/stories/abnormal_kubernetes_behavior_using_splunk_infrastructure_monitoring.yml index 47f4cfcb1d9..d035c5a7117 100644 --- a/stories/abnormal_kubernetes_behavior_using_splunk_infrastructure_monitoring.yml +++ b/stories/abnormal_kubernetes_behavior_using_splunk_infrastructure_monitoring.yml @@ -1,27 +1,19 @@ name: Abnormal Kubernetes Behavior using Splunk Infrastructure Monitoring id: 7589023b-3d98-42b3-ab1c-bb498e68fc2d -version: 1 -date: '2024-01-08' +version: 2 +creation_date: '2024-01-10' +modification_date: '2026-05-13' author: 'Matthew Moore, Patrick Bareiss, Splunk' status: production -description: Kubernetes, a complex container orchestration system, is susceptible to a variety of security threats. - This story delves into the different strategies and methods adversaries employ to exploit Kubernetes environments. - These include attacks on the control plane, exploitation of misconfigurations, and breaches of containerized applications. - Observability data, such as metrics, play a crucial role in identifying abnormal and potentially malicious behavior within these environments. -narrative: - Kubernetes, a complex container orchestration system, is a prime target for adversaries due to its widespread use and inherent complexity.

This vulnerability allows attackers to access sensitive ColdFusion Administrator endpoints by exploiting a flaw in the URL path validation. Disturbingly, this flaw can be chained with another critical vulnerability, CVE-2023-26360, which has been actively exploited. The latter enables unauthorized arbitrary code execution and file reading. Adobe has promptly addressed these vulnerabilities, but the intricacies and potential ramifications of their combination underscore the importance of immediate action by organizations. With active exploitation in the wild and the ability to bypass established security measures, the situation is alarming. Organizations are urged to apply the updates provided by Adobe immediately, considering the active threat landscape and the severe implications of these chained vulnerabilities. -narrative: Adobe ColdFusion, a prominent application server, has been thrust into the cybersecurity spotlight due to two intertwined vulnerabilities. The first, CVE-2023-29298, identified by Rapid7 in July 2023, pertains to an access control bypass in ColdFusion's security mechanisms. This flaw allows attackers to access protected ColdFusion Administrator endpoints simply by manipulating the URL path, specifically by inserting an additional forward slash. - Compounding the threat is the revelation that CVE-2023-29298 can be chained with CVE-2023-26360, another severe ColdFusion vulnerability. This latter vulnerability, which has seen active exploitation, permits unauthorized attackers to execute arbitrary code or read arbitrary files on the affected system. In practice, an attacker could exploit the access control bypass to access sensitive ColdFusion endpoints and subsequently exploit the arbitrary code execution vulnerability, broadening their control and access over the targeted system. - The consequences of these vulnerabilities are manifold. Attackers can potentially login to the ColdFusion Administrator with known credentials, bruteforce their way in, leak sensitive information, or exploit other vulnerabilities in the exposed CFM and CFC files.

The first, CVE-2023-29298, identified by Rapid7 in July 2023, pertains to an access control bypass in ColdFusion's security mechanisms. This flaw allows attackers to access protected ColdFusion Administrator endpoints simply by manipulating the URL path, specifically by inserting an additional forward slash. Compounding the threat is the revelation that CVE-2023-29298 can be chained with CVE-2023-26360, another severe ColdFusion vulnerability. This latter vulnerability, which has seen active exploitation, permits unauthorized attackers to execute arbitrary code or read arbitrary files on the affected system. In practice, an attacker could exploit the access control bypass to access sensitive ColdFusion endpoints and subsequently exploit the arbitrary code execution vulnerability, broadening their control and access over the targeted system. The consequences of these vulnerabilities are manifold. Attackers can potentially login to the ColdFusion Administrator with known credentials, bruteforce their way in, leak sensitive information, or exploit other vulnerabilities in the exposed CFM and CFC files. This combination of vulnerabilities significantly heightens the risk profile for organizations using the affected versions of Adobe ColdFusion. Addressing the urgency, Adobe released fixes for these vulnerabilities in July 2023, urging organizations to update to ColdFusion 2023 GA build, ColdFusion 2021 Update 7, and ColdFusion 2018 Update 17. However, Rapid7's disclosure highlights a potential incomplete fix, suggesting that organizations should remain vigilant and proactive in their security measures.\nIn conclusion, the discovery of these vulnerabilities and their potential to be exploited in tandem presents a significant security challenge.

Attackers leverage this by first uploading a malicious serialized object disguised as a session file through an HTTP PUT request. Once the file is uploaded, they manipulate the JSESSIONID cookie to reference this malicious file, forcing Tomcat to deserialize the content and potentially execute arbitrary code.

Recent activity relies on spear phishing attachments that deliver Windows shortcut or compiled HTML Help files, which stage artifacts in ProgramData and establish persistence through scheduled tasks and Run key modifications. The campaign centralizes command and control on a single server and uses standard web protocols with Base64 and XOR encoding to move data and instructions. narrative: The intrusion chain begins with phishing delivered archives that drop a Windows shortcut or CHM file to launch simple stagers. These stagers connect to a single C2 to fetch additional components and write them to ProgramData, where a task named MicrosoftUpdate and a Run entry are created for persistence. Rustonotto, a Rust compiled backdoor, provides basic command execution while a PowerShell variant known as Chinotto may be used interchangeably for early control. During hands on keyboard activity the actor retrieves a CAB archive and expands it on disk, then launches a legitimate Python module that side loads a compiled Python component internally named TransactedHollowing.py. This module reads a Base64 encoded and XOR encrypted payload from disk, decrypts it, and performs Process Doppelgänging via Windows Transactional NTFS to map the payload into a suspended legitimate process and pivot execution through thread context manipulation. Once resident, FadeStealer activates keylogging, screen capture, and device monitoring features and exfiltrates collected data as password protected RAR archives over HTTP to the same controller. The observed behaviors offer multiple opportunities for detection, including CHM and LNK execution, staging and expansion in ProgramData, scheduled task and Run key persistence, Python loader decode patterns, TxF backed section mapping, and RAR based exfiltration over web protocols. references: -- https://www.zscaler.com/blogs/security-research/apt37-targets-windows-rust-backdoor-and-python-loader -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://www.zscaler.com/blogs/security-research/apt37-targets-windows-rust-backdoor-and-python-loader +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/arcanedoor.yml b/stories/arcanedoor.yml index 50c8d1598fd..b5acab1da29 100644 --- a/stories/arcanedoor.yml +++ b/stories/arcanedoor.yml @@ -1,33 +1,33 @@ name: ArcaneDoor id: 7f2b9eac-0df5-4d0c-9e35-2b8fd552c9f1 -version: 2 -date: '2025-09-23' +version: 3 +creation_date: '2025-09-25' +modification_date: '2026-05-13' author: Bhavin Patel, Micheal Haag, Splunk status: production description: Attackers were observed to have exploited multiple zero-day vulnerabilities targeting certain Cisco Adaptive Security Appliance (ASA) 5500-X Series devices that were running Cisco Secure Firewall ASA Software with VPN web services enabled to implant malware, execute commands, and potentially exfiltrate data from the compromised devices. narrative: | - ArcaneDoor, a state-sponsored cyberespionage campaign targeting perimeter network devices from multiple vendors. + ArcaneDoor, a state-sponsored cyberespionage campaign targeting perimeter network devices from multiple vendors. - In May 2025, Cisco was engaged by multiple government agencies that provide incident response services to government organizations to support the investigation of attacks that were targeting certain Cisco Adaptive Security Appliance (ASA) 5500-X Series devices that were running Cisco Secure Firewall ASA Software with VPN web services enabled to implant malware, execute commands, and potentially exfiltrate data from the compromised devices.

Look for registry changes disabling security features or altering startup configurations. Track high-volume file modifications in rapid succession, indicative of ransomware encryption. Additionally, unauthorized remote service executions. Cross-reference endpoint logs, EDR alerts, and SIEM detections to correlate malicious activity. Behavioral analytics and heuristic-based detections can enhance visibility into evolving tactics. Implement robust monitoring and response mechanisms to mitigate Black Basta’s impact effectively. narrative: Black Basta ransomware is a highly sophisticated and fast-moving threat that has been targeting organizations worldwide, often disrupting critical operations and demanding hefty ransoms. It operates as a double extortion ransomware, encrypting victim data while simultaneously exfiltrating it to pressure victims into paying. The attack typically begins with initial access via phishing emails, compromised credentials, or exploitation of vulnerabilities in remote desktop services. Once inside, attackers escalate privileges, disable security defenses, and deploy the ransomware payload. The malware rapidly encrypts files across local and networked drives, deleting shadow copies to prevent recovery. It often abuses legitimate system tools like wmic.exe and rundll32.exe, to evade detection. Simultaneously, it establishes command-and-control (C2) connections to exfiltrate sensitive data. The impact is severe—disrupting business operations, exposing confidential information, and leaving organizations with few options for recovery. Early detection, network segmentation, and strong endpoint defenses are crucial to mitigating the risk posed by Black Basta. references: -- https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-131a -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-131a +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/blackbyte_ransomware.yml b/stories/blackbyte_ransomware.yml index f74d3ff9c92..6998da28b7f 100644 --- a/stories/blackbyte_ransomware.yml +++ b/stories/blackbyte_ransomware.yml @@ -1,26 +1,18 @@ name: BlackByte Ransomware id: b18259ac-0746-45d7-bd1f-81d65274a80b -version: 1 -date: '2023-07-10' +version: 2 +creation_date: '2023-07-10' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production -description: Leverage searches that allow you to detect and investigate unusual activities - that might relate to the BlackByte ransomware, including looking for file writes - associated with BlackByte, persistence, initial access, account registry - modification and more. -narrative: BlackByte ransomware campaigns targeting business operations, - involve the use of ransomware payloads, infection chain to collect and exfiltrate data and drop payload on the targeted system. - BlackByte Ransomware operates by infiltrating a system through various methods, such as malicious email attachments, exploit kits, - or compromised websites.

The FBI assesses that a significant percentage of these operations aim to obtain network access for collaboration with ransomware affiliates. The actors typically use Shodan to identify vulnerable devices, then exploit public-facing networking equipment such as Citrix Netscaler, F5 BIG-IP, and various VPNs. They deploy webshells, create local accounts, and manipulate existing ones to maintain access. Post-exploitation, they repurpose credentials, disable security software, and use remote access tools. The group collaborates with ransomware affiliates like NoEscape, Ransomhouse, and ALPHV, actively participating in network lockdowns and extortion strategies. Defenders should prioritize patching public-facing devices, monitoring for unauthorized accounts and suspicious PowerShell activity, implementing strong access controls, and regularly reviewing logs for signs of compromise. references: - - https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-241a - - https://gist.github.com/MHaggis/7e67b659af9148fa593cf2402edebb41 - - https://techcommunity.microsoft.com/t5/core-infrastructure-and-security/want-remote-powershell-management-from-your-browser-see-how-pswa/ba-p/255764 - - https://learn.microsoft.com/en-us/powershell/module/powershellwebaccess/?view=winserver2012r2-ps - - https://arz101.medium.com/hackthebox-acute-ee0308b9b443 -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection - cve: - - CVE-2024-24919 - - CVE-2024-3400 - - CVE-2019-19781 - - CVE-2023-3519 - - CVE-2022-1388 - - CVE-2024-21887 + - https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-241a + - https://gist.github.com/MHaggis/7e67b659af9148fa593cf2402edebb41 + - https://techcommunity.microsoft.com/t5/core-infrastructure-and-security/want-remote-powershell-management-from-your-browser-see-how-pswa/ba-p/255764 + - https://learn.microsoft.com/en-us/powershell/module/powershellwebaccess/?view=winserver2012r2-ps + - https://arz101.medium.com/hackthebox-acute-ee0308b9b443 +cve: + - CVE-2024-24919 + - CVE-2024-3400 + - CVE-2019-19781 + - CVE-2023-3519 + - CVE-2022-1388 + - CVE-2024-21887 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/cisco_catalyst_sd_wan_analytics.yml b/stories/cisco_catalyst_sd_wan_analytics.yml index a588ca3c055..48e8b579d77 100644 --- a/stories/cisco_catalyst_sd_wan_analytics.yml +++ b/stories/cisco_catalyst_sd_wan_analytics.yml @@ -1,7 +1,8 @@ name: Cisco Catalyst SD-WAN Analytics id: 7ec01b6e-95fa-4a89-86b7-ada08cf237de -version: 1 -date: '2026-03-02' +version: 2 +creation_date: '2026-03-03' +modification_date: '2026-05-13' author: Nasreddine Bencherchali, Splunk status: production description: | @@ -19,11 +20,10 @@ references: - https://www.cisco.com/c/en/us/td/docs/routers/sdwan/17-x/systems-interfaces/systems-interfaces-guide-17-x/system-logging.html#config-sys-logging - https://sec.cloudapps.cisco.com/security/center/resources/Cisco-Catalyst-SD-WAN-HardeningGuide - https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-rpa-EHchtZk -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/cisco_duo_suspicious_activity.yml b/stories/cisco_duo_suspicious_activity.yml index 541674b2473..9f48fbb6479 100644 --- a/stories/cisco_duo_suspicious_activity.yml +++ b/stories/cisco_duo_suspicious_activity.yml @@ -1,24 +1,24 @@ name: Cisco Duo Suspicious Activity id: f2f0713d-2aa3-47c7-b773-ec1e9935e35a -version: 1 -date: '2024-07-08' +version: 2 +creation_date: '2025-07-10' +modification_date: '2026-05-13' author: Patrick Bareiss, Splunk status: production description: This analytics story focuses on identifying suspicious activities and potential account compromise events within environments protected by Duo multi-factor authentication (MFA).

Successful exploitation of this vulnerability allows an attacker to create an account on the affected device with privilege level 15 access, effectively granting them full control of the compromised device and allowing possible subsequent unauthorized activity. narrative: Cisco discovered early evidence of potentially malicious activity on September 28, 2023, when a case was opened with Cisco's Technical Assistance Center (TAC) that identified unusual behavior on a customer device. Upon further investigation, they observed what they have determined to be related activity as early as September 18. The activity included an authorized user creating a local user account under the username cisco_tac_admin from a suspicious IP address. On October 12, Cisco Talos Incident Response (Talos IR) and TAC detected what they later determined to be an additional cluster of related activity that began on that same day. In this cluster, an unauthorized user was observed creating a local user account under the name cisco_support from a second suspicious IP address. Unlike the September case, this October activity included several subsequent actions, including the deployment of an implant consisting of a configuration file (cisco_service.conf). The configuration file defines the new web server endpoint (URI path) used to interact with the implant. That endpoint receives certain parameters, described in more detail below, that allows the actor to execute arbitrary commands at the system level or IOS level. For the implant to become active, the web server must be restarted; in at least one observed case the server was not restarted so the implant never became active despite being installed. references: -- https://blog.talosintelligence.com/active-exploitation-of-cisco-ios-xe-software/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://blog.talosintelligence.com/active-exploitation-of-cisco-ios-xe-software/ +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/cisco_isovalent_suspicious_activity.yml b/stories/cisco_isovalent_suspicious_activity.yml index cb8fcca72e2..5d54a8483cb 100644 --- a/stories/cisco_isovalent_suspicious_activity.yml +++ b/stories/cisco_isovalent_suspicious_activity.yml @@ -1,25 +1,25 @@ name: Cisco Isovalent Suspicious Activity id: 245ac99a-1355-44fe-9ef7-a7e826e20c6f -version: 1 -date: '2025-11-18' +version: 2 +creation_date: '2026-01-05' +modification_date: '2026-05-13' author: Bhavin Patel, Splunk status: production description: This analytics story focuses on identifying suspicious activities and potential security threats within environments using Cisco Isovalent in Kubernetes.

This vulnerability, dubbed "CitrixBleed 2," represents a memory disclosure flaw that can result in unauthorized data disclosure if exploited. Unlike CVE-2023-4966 (the original CitrixBleed), this vulnerability is triggered by sending POST requests with incomplete form data to the /p/u/doAuthentication.do endpoint, causing the device to leak memory contents including session tokens, authentication cookies, and other critical data that can lead to session hijacking and unauthorized access. The Cybersecurity and Infrastructure Security Agency (CISA) has added CVE-2025-5777 to its Known Exploited and Vulnerabilities Catalog due to active exploitation in the wild since mid-June 2025. No workarounds are available for this vulnerability, and immediate installation of the recommended builds is strongly advised. narrative: On June 17, 2025, Cloud Software Group released emergency security updates to fix CVE-2025-5777, a critical vulnerability affecting NetScaler ADC and NetScaler Gateway. This vulnerability, known as "CitrixBleed 2," is a memory disclosure flaw that allows unauthenticated remote attackers to obtain sensitive information from NetScaler appliances configured as Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual servers. The primary attack vector involves sending POST requests with incomplete form data (such as "login=" without a value) to the "/p/u/doAuthentication.do" endpoint, causing the device to leak up to 127 bytes of adjacent memory contents including session tokens, SAML StateContext, MFA tokens, and other authentication materials. A secondary attack vector still uses oversized Host headers targeting "/nf/auth/startwebview.do" similar to the original CitrixBleed, but the primary exploitation method represents a new vulnerability in form data processing. Security researchers have observed active exploitation attempts since mid-June 2025, with threat actors using automated tools including HeadlessChrome user agents to scan for vulnerable instances. The leaked session tokens can be directly reused to bypass authentication, including multi-factor authentication (MFA), allowing attackers to gain unauthorized access to protected resources and deploy web shells for persistence. CISA added CVE-2025-5777 to its Known Exploited Vulnerabilities Catalog on June 23, 2025, indicating widespread exploitation attempts. Organizations are strongly advised to immediately apply patches, kill all active sessions, monitor for signs of compromise, and implement additional detection for both the primary POST-based attack vector and the secondary Host header attack vector as no workarounds are available for this critical vulnerability. references: - - https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX693420 - - https://www.netscaler.com/blog/news/critical-security-updates-for-netscaler-netscaler-gateway-and-netscaler-console/ - - https://github.com/mingshenhk/CitrixBleed-2-CVE-2025-5777-PoC- - - https://horizon3.ai/attack-research/attack-blogs/cve-2025-5777-citrixbleed-2-write-up-maybe/ - - https://labs.watchtowr.com/how-much-more-must-we-bleed-citrix-netscaler-memory-disclosure-citrixbleed-2-cve-2025-5777/ - - https://doublepulsar.com/citrixbleed-2-exploitation-started-mid-june-how-to-spot-it-f3106392aa71 - - https://reliaquest.com/blog/threat-spotlight-citrix-bleed-2-vulnerability-in-netscaler-adc-gateway-devices/ - - https://arcticwolf.com/resources/blog/cve-2025-5777/ - - https://www.computerweekly.com/news/366626717/Citrix-Bleed-2-under-active-attack-reports-suggest - - https://www.tenable.com/blog/cve-2025-5777-cve-2025-6543-frequently-asked-questions-about-citrixbleed-2 -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX693420 + - https://www.netscaler.com/blog/news/critical-security-updates-for-netscaler-netscaler-gateway-and-netscaler-console/ + - https://github.com/mingshenhk/CitrixBleed-2-CVE-2025-5777-PoC- + - https://horizon3.ai/attack-research/attack-blogs/cve-2025-5777-citrixbleed-2-write-up-maybe/ + - https://labs.watchtowr.com/how-much-more-must-we-bleed-citrix-netscaler-memory-disclosure-citrixbleed-2-cve-2025-5777/ + - https://doublepulsar.com/citrixbleed-2-exploitation-started-mid-june-how-to-spot-it-f3106392aa71 + - https://reliaquest.com/blog/threat-spotlight-citrix-bleed-2-vulnerability-in-netscaler-adc-gateway-devices/ + - https://arcticwolf.com/resources/blog/cve-2025-5777/ + - https://www.computerweekly.com/news/366626717/Citrix-Bleed-2-under-active-attack-reports-suggest + - https://www.tenable.com/blog/cve-2025-5777-cve-2025-6543-frequently-asked-questions-about-citrixbleed-2 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/citrix_netscaler_adc_cve_2023_3519.yml b/stories/citrix_netscaler_adc_cve_2023_3519.yml index 40bcb23015c..c7b638d5803 100644 --- a/stories/citrix_netscaler_adc_cve_2023_3519.yml +++ b/stories/citrix_netscaler_adc_cve_2023_3519.yml @@ -1,26 +1,20 @@ name: Citrix Netscaler ADC CVE-2023-3519 id: 094df1fe-4345-4c01-8a0f-c65cf7b758bd -version: 1 -date: '2023-07-20' +version: 2 +creation_date: '2023-07-20' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: The CVE-2023-3519 vulnerability in NetScaler (formerly Citrix) Application Delivery Controller (ADC) and NetScaler Gateway has been exploited by threat actors, as detailed in a recent advisory.

The advisory offers a comprehensive examination of the threat actors' tactics, techniques, and procedures (TTPs), alongside recommended detection methods and incident response guidelines. Immediate patch application from Citrix and the use of the detection guidance in the advisory is strongly recommended for critical infrastructure organizations to mitigate system compromises. -narrative: Recent advisories have highlighted the exploitation of CVE-2023-3519, a critical vulnerability in Citrix's NetScaler Application Delivery Controller (ADC) and NetScaler Gateway. In June 2023, threat actors utilized this vulnerability to implant a webshell on a NetScaler ADC appliance within a critical infrastructure organization's non-production environment. This action granted them the ability to perform active directory discovery, data collection, and exfiltration. Notably, attempts for lateral movement to a domain controller were obstructed by network-segmentation controls. - - The compromised organization reported the breach, leading Citrix to issue a patch on July 18, 2023. Multiple advisories have since outlined the threat actors' tactics, techniques, and procedures (TTPs), including their initial access, persistence, privilege escalation, defense evasion, credential access, discovery, collection, command and control, and impact. These advisories also provide detection methods and recommend incident response measures. - - The threat actors executed several activities during their attack, such as uploading a TGZ file with a generic webshell, discovery script, and setuid binary on the ADC appliance; conducting SMB scanning on the subnet; using the webshell for active directory enumeration and data exfiltration; and accessing NetScaler configuration files and decryption keys. They also decrypted an active directory credential, queried the active directory for various information, encrypted collected data, exfiltrated it as an image file, and attempted to erase their artifacts. Despite these actions, further discovery and lateral movement were impeded due to the organization's network-segmentation controls. \ - - Advisories suggest conducting specific checks on the ADC shell interface to detect signs of compromise. If a compromise is detected, organizations should isolate potentially affected hosts, reimage compromised hosts, provide new account credentials, collect and review artifacts, and report the compromise. To mitigate the threat, organizations are advised to promptly install the relevant updates for NetScaler ADC and NetScaler Gateway, adhere to cybersecurity best practices, and apply robust network-segmentation controls on NetScaler appliances and other internet-facing devices. +narrative: "Recent advisories have highlighted the exploitation of CVE-2023-3519, a critical vulnerability in Citrix's NetScaler Application Delivery Controller (ADC) and NetScaler Gateway.

It scans the infected machine for wallet files, clipboard activity, and other cryptocurrency artifacts, focusing on intercepting sensitive information like private keys or transaction details. The malware communicates with a command-and-control (C2) server to transmit the harvested data and can dynamically adapt its behavior based on instructions received. Detection indicators include unusual network activity to suspicious IP addresses, unauthorized file access targeting cryptocurrency wallet directories, and anomalous clipboard usage associated with cryptocurrency strings (e.g., wallet addresses). Security solutions should monitor for these behaviors and implement heuristic analysis to identify deviations from normal system operations. Users are encouraged to maintain updated endpoint protection and avoid downloading files from untrusted sources to mitigate the risk posed by Crypto Stealer. narrative: In the ever-evolving landscape of cybercrime, Crypto Stealer emerges as a sophisticated malware targeting the lucrative world of cryptocurrency. By exploiting system vulnerabilities, the malware actively scans for wallet files, clipboard data, and other digital assets, focusing on intercepting sensitive information like private keys and transaction details. Once deployed, Crypto Stealer communicates with a command-and-control (C2) server to exfiltrate stolen data and receive updated instructions for further exploitation. Notably, it often works in tandem with other malicious components, such as XMRig, a widely abused cryptocurrency miner that hijacks system resources for illicit mining operations, and ClipBanker, which manipulates clipboard activity to replace wallet addresses in transactions with those controlled by attackers. These combined tactics maximize the attack's profitability while minimizing the victim's ability to detect the theft. Indicators of compromise include unauthorized access to cryptocurrency wallet files, suspicious clipboard behavior, and outbound connections to known malicious IP addresses. By understanding and recognizing these patterns, defenders can develop effective strategies to detect and mitigate threats like Crypto Stealer before significant damage occurs. references: [] -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/cve_2022_40684_fortinet_appliance_auth_bypass.yml b/stories/cve_2022_40684_fortinet_appliance_auth_bypass.yml index e9ab1a2528f..a91f195c5ed 100644 --- a/stories/cve_2022_40684_fortinet_appliance_auth_bypass.yml +++ b/stories/cve_2022_40684_fortinet_appliance_auth_bypass.yml @@ -1,22 +1,22 @@ name: CVE-2022-40684 Fortinet Appliance Auth bypass id: 55721831-577e-41be-beef-bdc03c81486a -version: 1 -date: '2022-10-14' +version: 2 +creation_date: '2022-10-14' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production -description: Fortinet recently patched a critical authentication bypass vulnerability in their FortiOS, FortiProxy, and FortiSwitchManager projects CVE-2022-40684. +description: Fortinet recently patched a critical authentication bypass vulnerability in their FortiOS, FortiProxy, and FortiSwitchManager projects CVE-2022-40684. narrative: FortiOS exposes a management web portal that allows a user configure the system. Additionally, a user can SSH into the system which exposes a locked down CLI interface. Any HTTP requests to the management interface of the system that match the conditions above should be cause for concern. An attacker can use this vulnerability to do just about anything they want to the vulnerable system. This includes changing network configurations, adding new users, and initiating packet captures. Note that this is not the only way to exploit this vulnerability and there may be other sets of conditions that work. For instance, a modified version of this exploit uses the User-Agent Node.js. This exploit seems to follow a trend among recently discovered enterprise software vulnerabilities where HTTP headers are improperly validated or overly trusted.

Monitoring changes to critical registry values and the execution of specific tools used for SDDL modifications can help identify such malicious activities. references: -- https://web.archive.org/web/20220710181255/https://blog.minerva-labs.com/lockbit-3.0-aka-lockbit-black-is-here-with-a-new-icon-new-ransom-note-new-wallpaper-but-less-evasiveness -- https://learn.microsoft.com/en-us/troubleshoot/windows-server/group-policy/set-event-log-security-locally-or-via-group-policy -- https://0xv1n.github.io/posts/scmanager/ -- https://www.sans.org/blog/red-team-tactics-hiding-windows-services/ -- https://news.sophos.com/wp-content/uploads/2020/06/glupteba_final-1.pdf -- https://www.pwc.com/gx/en/issues/cybersecurity/cyber-threat-intelligence/cyber-year-in-retrospect/yir-cyber-threats-report-download.pdf -- https://www.welivesecurity.com/en/eset-research/romcom-exploits-firefox-and-windows-zero-days-in-the-wild/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://web.archive.org/web/20220710181255/https://blog.minerva-labs.com/lockbit-3.0-aka-lockbit-black-is-here-with-a-new-icon-new-ransom-note-new-wallpaper-but-less-evasiveness + - https://learn.microsoft.com/en-us/troubleshoot/windows-server/group-policy/set-event-log-security-locally-or-via-group-policy + - https://0xv1n.github.io/posts/scmanager/ + - https://www.sans.org/blog/red-team-tactics-hiding-windows-services/ + - https://news.sophos.com/wp-content/uploads/2020/06/glupteba_final-1.pdf + - https://www.pwc.com/gx/en/issues/cybersecurity/cyber-threat-intelligence/cyber-year-in-retrospect/yir-cyber-threats-report-download.pdf + - https://www.welivesecurity.com/en/eset-research/romcom-exploits-firefox-and-windows-zero-days-in-the-wild/ +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/deobfuscate_decode_files_or_information.yml b/stories/deobfuscate_decode_files_or_information.yml index 2e93f5198f4..12b590de3a1 100644 --- a/stories/deobfuscate_decode_files_or_information.yml +++ b/stories/deobfuscate_decode_files_or_information.yml @@ -1,26 +1,18 @@ name: Deobfuscate-Decode Files or Information id: 0bd01a54-8cbe-11eb-abcd-acde48001122 -version: 1 -date: '2021-03-24' +version: 2 +creation_date: '2021-03-25' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production -description: Adversaries may use Obfuscated Files or Information to hide artifacts - of an intrusion from analysis. -narrative: An example of obfuscated files is `Certutil.exe` usage to encode a portable - executable to a certificate file, which is base64 encoded, to hide the originating - file.

Analysis on VirusTotal shows multiple detections labeling it as “Trojan.Wiper” or “DiskWiper,” indicating destructive intent and possible use of raw disk access to bypass file-level recovery.

First observed in early 2024 and increasing through 2025, these campaigns use deceptive interfaces that mimic legitimate CAPTCHA systems to trick users into executing malicious commands. narrative: Fake CAPTCHA campaigns represent a sophisticated evolution in social engineering attacks that rely entirely on manipulating user behavior rather than exploiting technical vulnerabilities. These attacks begin with victims landing on malicious websites through phishing emails, malvertising, or compromised legitimate sites. The site presents what appears to be a standard CAPTCHA verification interface with familiar branding from Google reCAPTCHA or Cloudflare. When users interact with the fake CAPTCHA, malicious JavaScript silently copies commands to their clipboard. Users are then instructed to perform additional verification steps such as pressing Windows+R followed by Ctrl+V, unknowingly pasting and executing malicious commands. These commands typically download and run additional malware using PowerShell scripts that operate in hidden windows. Common payloads include information stealers (Lumma, Redline, Vidar, PureLog), Remote Access Trojans (NetSupport, XWorm, AsyncRAT, Quasar), and multi-stage payloads that can deploy multiple malware families from a single infection. references: -- https://urlhaus.abuse.ch/ -- https://www.proofpoint.com/us/blog/threat-insight/security-brief-clickfix-social-engineering-technique-floods-threat-landscape -- https://reliaquest.com/blog/using-captcha-for-compromise/ -- https://attack.mitre.org/techniques/T1204/001/ -- https://github.com/MHaggis/ClickGrab -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://urlhaus.abuse.ch/ + - https://www.proofpoint.com/us/blog/threat-insight/security-brief-clickfix-social-engineering-technique-floods-threat-landscape + - https://reliaquest.com/blog/using-captcha-for-compromise/ + - https://attack.mitre.org/techniques/T1204/001/ + - https://github.com/MHaggis/ClickGrab +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/fin7.yml b/stories/fin7.yml index 04e667e2b58..5cfded4ffac 100644 --- a/stories/fin7.yml +++ b/stories/fin7.yml @@ -1,31 +1,20 @@ name: FIN7 id: df2b00d3-06ba-49f1-b253-b19cef19b569 -version: 1 -date: '2021-09-14' +version: 2 +creation_date: '2021-09-14' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production -description: Leverage searches that allow you to detect and investigate unusual activities - that might relate to the FIN7 JS Implant and JSSLoader, including looking for Image - Loading of ldap and wmi modules, associated with its payload, data collection and - script execution. -narrative: FIN7 is a Russian criminal advanced persistent threat group that has primarily - targeted the U.S. retail, restaurant, and hospitality sectors since mid-2015.

However, they primarily rely on living-off-the-land techniques and hands-on-keyboard activity. Initial access is achieved by exploiting known vulnerabilities in public-facing servers and deploying web shells. Following initial access, Flax Typhoon uses command-line tools to establish persistent access over the remote desktop protocol, deploy a VPN connection to actor-controlled network infrastructure, and collect credentials from compromised systems.

These emails, once accessed, lead to a multi-stage cyber operation downloading and executing malicious payloads. Concurrently, Zscaler's "Steal-It" campaign detection revealed striking similarities, hinting at a shared origin - APT28 or Fancy Bear. This notorious group, linked to Russia's GRU, utilizes legitimate platforms like Mockbin, making detection challenging. Their operations underline the evolving cyber threat landscape and stress the importance of advanced defenses. narrative: APT28, also known as Fancy Bear, blends stealth and expertise in its cyber operations. Affiliated with Russia's GRU, their signature move involves spear-phishing emails, leading to multi-tiered cyberattacks. In Ukraine's recent breach, a ZIP archive's execution triggered a series of actions, culminating in information flow redirection via the TOR network. Simultaneously, Zscaler's "Steal-It" campaign pinpointed similar tactics, specifically targeting NTLMv2 hashes. This campaign used ZIP archives containing LNK files to exfiltrate data via Mockbin. APT28's hallmark is their "Living Off The Land" strategy, manipulating legitimate tools and services to blend in, evading detection. Their innovative tactics, coupled with a geofencing focus on specific regions, make them a formidable cyber threat, highlighting the urgent need for advanced defense strategies. references: -- https://cert.gov.ua/article/5702579 -- https://www.zscaler.com/blogs/security-research/steal-it-campaign -- https://attack.mitre.org/groups/G0007/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://cert.gov.ua/article/5702579 + - https://www.zscaler.com/blogs/security-research/steal-it-campaign + - https://attack.mitre.org/groups/G0007/ +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/fortinet_fortinac_cve_2022_39952.yml b/stories/fortinet_fortinac_cve_2022_39952.yml index f972d5030f2..c7541eb5023 100644 --- a/stories/fortinet_fortinac_cve_2022_39952.yml +++ b/stories/fortinet_fortinac_cve_2022_39952.yml @@ -1,23 +1,20 @@ name: Fortinet FortiNAC CVE-2022-39952 id: 2833a527-3b7f-41af-a950-39f7bbaff819 -version: 1 -date: '2023-02-21' +version: 2 +creation_date: '2023-02-21' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: On Thursday, 16 February 2023, Fortinet released a PSIRT that details CVE-2022-39952, a critical vulnerability affecting its FortiNAC product (Horizon3.ai). -narrative: This vulnerability, discovered by Gwendal Guegniaud of Fortinet, allows an unauthenticated attacker to write arbitrary files on the system and as a result obtain remote code execution in the context of the root user (Horizon3.ai). - Impacting FortiNAC, is tracked as CVE-2022-39952 and has a CVSS v3 score of 9.8 (critical). - FortiNAC is a network access control solution that helps organizations gain real time network visibility, enforce security policies, and detect and mitigate threats. - An external control of file name or path vulnerability CWE-73 in FortiNAC webserver may allow an unauthenticated attacker to perform arbitrary write on the system, reads the security advisory. -references: - - https://www.horizon3.ai/fortinet-fortinac-cve-2022-39952-deep-dive-and-iocs/ - - https://viz.greynoise.io/tag/fortinac-rce-attempt?days=30 - - https://www.bleepingcomputer.com/news/security/fortinet-fixes-critical-rce-flaws-in-fortinac-and-fortiweb/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection +narrative: This vulnerability, discovered by Gwendal Guegniaud of Fortinet, allows an unauthenticated attacker to write arbitrary files on the system and as a result obtain remote code execution in the context of the root user (Horizon3.ai).

The group employs advanced techniques including PowerShell infection chains, SSH-based persistence, and custom ransomware payloads to compromise and encrypt victim systems. narrative: Hellcat Ransomware represents a significant threat to organizations across multiple sectors. The group's operations begin with initial access through phishing campaigns and exploitation of public-facing application vulnerabilities, including known CVEs in Palo Alto PAN-OS software (CVE-2024-0012, CVE-2024-9474). Upon gaining access, Hellcat operators deploy sophisticated PowerShell infection chains to establish persistence, evade detection, and install command-and-control infrastructure. A distinctive characteristic of Hellcat's tactics is their use of SSH-based persistence mechanisms. Operators create new SSH users with administrative privileges and install unique SSH keys to maintain long-term access to compromised systems. They also deploy backdoor malware as a backup persistence mechanism if SSH access fails. For command and control, Hellcat leverages SliverC2 and Cobalt Strike frameworks, combined with custom infrastructure including domains like waifu[.]cat for data exfiltration. The group employs SFTP as their primary exfiltration mechanism, moving stolen data to attacker-controlled servers before deploying their custom ransomware payloads. Throughout their operations, Hellcat extensively uses Living-off-the-Land binaries (LOLBAS) and obfuscated PowerShell scripts to evade security controls. They also deploy information-stealing malware like LummaStealer to harvest credentials and sensitive data. Notable victims include Schneider Electric, Telefonica, Pinger, Israel's Knesset, Dell, and CapGemini. The group is led by founding member "Pryx" with other members including "Grep" who have been attributed to several high-profile attacks. Hellcat has demonstrated connections to other ransomware groups including Underground Team and Morpheus, suggesting a broader ecosystem of threat actors sharing tools and techniques. Organizations should implement robust security measures including PowerShell Script Block Logging, Sysmon monitoring, SSH activity monitoring, and EDR solutions to detect and respond to Hellcat ransomware activities. references: -- https://www.bridewell.com/insights/blogs/detail/who-are-hellcat-ransomware-group -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection - cve: - - CVE-2024-0012 - - CVE-2024-9474 + - https://www.bridewell.com/insights/blogs/detail/who-are-hellcat-ransomware-group +cve: + - CVE-2024-0012 + - CVE-2024-9474 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/hermetic_wiper.yml b/stories/hermetic_wiper.yml index f3334cd04ad..cac4176038e 100644 --- a/stories/hermetic_wiper.yml +++ b/stories/hermetic_wiper.yml @@ -1,23 +1,21 @@ name: Hermetic Wiper id: b7511c2e-9a10-11ec-99e3-acde48001122 -version: 1 -date: '2022-03-02' +version: 2 +creation_date: '2022-03-02' +modification_date: '2026-05-13' author: Teoderick Contreras, Rod Soto, Michael Haag, Splunk status: production -description: This analytic story contains detections that allow security analysts to detect and investigate unusual activities - that might relate to the destructive malware targeting Ukrainian organizations also known as "Hermetic Wiper".

FBI is aware of Interlock ransomware encryptors designed for both Windows and Linux operating systems; these encryptors have been observed encrypting virtual machines (VMs) across both operating systems. FBI observed actors obtaining initial access via drive-by download from compromised legitimate websites, which is an uncommon method among ransomware groups. Actors were also observed using the ClickFix social engineering technique for initial access, in which victims are tricked into executing a malicious payload under the guise of fixing an issue on the victim’s system.

Interlock RAT distinguishes itself with a lightweight binary, encrypted communications, and a plugin-based architecture that allows attackers to load new capabilities post-compromise. Interlock employs a multi-stage attack chain, starting by compromising legitimate websites that deliver fake browser updates, such as Google Chrome or MS Edge installers. These fake installers execute a PowerShell backdoor facilitating the execution of multiple tools, and ultimately leading to the ransomware payload delivery. references: -- https://www.cisa.gov/news-events/cybersecurity-advisories/aa25-203a -- https://blog.sekoia.io/interlock-ransomware-evolving-under-the-radar/ -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://www.cisa.gov/news-events/cybersecurity-advisories/aa25-203a + - https://blog.sekoia.io/interlock-ransomware-evolving-under-the-radar/ +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/ivanti_connect_secure_vpn_vulnerabilities.yml b/stories/ivanti_connect_secure_vpn_vulnerabilities.yml index e2a272010e5..7ad94db381f 100644 --- a/stories/ivanti_connect_secure_vpn_vulnerabilities.yml +++ b/stories/ivanti_connect_secure_vpn_vulnerabilities.yml @@ -1,28 +1,28 @@ name: Ivanti Connect Secure VPN Vulnerabilities id: e3b5c3b8-082b-4b4e-b2c9-47ed79e2a5ab -version: 1 -date: '2024-01-16' +version: 2 +creation_date: '2024-01-17' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: The following analytic story addresses critical vulnerabilities CVE-2023-46805 and CVE-2024-21887 in Ivanti Connect Secure and Ivanti Policy Secure Gateways.

Such traffic is abnormal in most enterprise environments and may be embedded with base64-encoded prompts that instruct the malware to generate and execute dynamic Windows commands for reconnaissance and data theft. Detection should also flag execution of AI-generated command chains invoking utilities like systeminfo, net start, tasklist, dsquery, and recursive file copy operations into the %ProgramData%\info\ directory. Additional heuristics include spotting phishing ZIP attachments with .pif binaries disguised as PDF or image viewers, which are commonly used for initial delivery of LameHug. narrative: LAMEHUG is a Python-based infostealer discovered by CERT-UA in 2025 and linked with moderate confidence to APT28. It is distributed through spear-phishing emails impersonating Ukrainian government officials, where malicious ZIP archives contain decoy .pif executables. Once executed, the malware communicates with an LLM hosted on Hugging Face (Qwen 2.5-Coder-32B-Instruct) to dynamically generate Windows commands for reconnaissance, credential harvesting, and document collection. Stolen data is staged locally and later exfiltrated via SFTP or HTTP POST to attacker-controlled servers. LameHug represents a new evolution in malware design, leveraging AI for real-time adaptability, making it harder to detect using static signatures or traditional defensive methods. references: -- https://cert.gov.ua/article/6284730 -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://cert.gov.ua/article/6284730 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/linux_living_off_the_land.yml b/stories/linux_living_off_the_land.yml index acecbea6339..3dc21d4d1cf 100644 --- a/stories/linux_living_off_the_land.yml +++ b/stories/linux_living_off_the_land.yml @@ -1,20 +1,18 @@ name: Linux Living Off The Land id: e405a2d7-dc8e-4227-8e9d-f60267b8c0cd -version: 1 -date: '2022-07-27' +version: 2 +creation_date: '2022-07-27' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: Linux Living Off The Land consists of binaries that may be used to bypass local security restrictions within misconfigured systems. -narrative: Similar to Windows LOLBAS project, the GTFOBins project focuses solely on Unix binaries that may be abused in multiple categories including Reverse Shell, File Upload, File Download and much more. - These binaries are native to the operating system and the functionality is typically native.

It permits remote code execution and it can allow an attacker to leak sensitive data, such as environment variables, or execute malicious software on the target system.' references: -- https://mbechler.github.io/2021/12/10/PSA_Log4Shell_JNDI_Injection/ -- https://www.fastly.com/blog/digging-deeper-into-log4shell-0day-rce-exploit-found-in-log4j -- https://www.crowdstrike.com/blog/log4j2-vulnerability-analysis-and-mitigation-recommendations/ -- https://www.lunasec.io/docs/blog/log4j-zero-day/ -- https://www.splunk.com/en_us/blog/security/log-jammin-log4j-2-rce.html -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Application Security + - https://mbechler.github.io/2021/12/10/PSA_Log4Shell_JNDI_Injection/ + - https://www.fastly.com/blog/digging-deeper-into-log4shell-0day-rce-exploit-found-in-log4j + - https://www.crowdstrike.com/blog/log4j2-vulnerability-analysis-and-mitigation-recommendations/ + - https://www.lunasec.io/docs/blog/log4j-zero-day/ + - https://www.splunk.com/en_us/blog/security/log-jammin-log4j-2-rce.html +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Application Security diff --git a/stories/lokibot.yml b/stories/lokibot.yml index 90bdbf01170..a8e7e39b43f 100644 --- a/stories/lokibot.yml +++ b/stories/lokibot.yml @@ -1,18 +1,18 @@ name: Lokibot id: d8db6b83-85b9-40f1-a6bc-28f6c6e3d487 -version: 1 -date: '2025-09-30' +version: 2 +creation_date: '2025-10-10' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production description: Lokibot is a prevalent information-stealing Trojan that primarily targets Windows and Android devices to pilfer sensitive data, including usernames, passwords, cryptocurrency wallets, and banking information. Detection often hinges on identifying its characteristic behaviors and network communications. It is commonly distributed via phishing emails containing malicious attachments (e.g., Office documents, RAR files) or through compromised websites. Once infected, Lokibot employs keylogging to capture credentials and exfiltrates stolen data to its command-and-control (C2) servers, often using HTTP with a distinct User-Agent string like "Mozilla/4.08 (Charon; Inferno)". Suspicious network traffic, unexpected system activity, or the presence of its specific C2 communication patterns are strong indicators of compromise. Antivirus and endpoint detection solutions are crucial for identifying and mitigating Lokibot infections. narrative: Lokibot's detection narrative often begins with the initial compromise, typically through a user opening a malicious attachment from a phishing email or visiting a compromised website. Once executed, the malware establishes persistence and begins its data-gathering operations, often employing keylogging to capture credentials and other sensitive information. Its presence might first be flagged by endpoint detection and response (EDR) solutions observing unusual process behavior, such as vbc.exe or other legitimate processes making unexpected network connections. Network monitoring tools can then identify suspicious outbound traffic, particularly HTTP requests to known Lokibot command-and-control (C2) servers, often characterized by specific User-Agent strings or patterns. Furthermore, the exfiltration of stolen data to these C2 infrastructures provides a critical detection point, allowing security teams to identify and respond to the compromise before significant data loss occurs. Antivirus signatures and behavioral analysis also play a role in identifying the Lokibot executable itself or its attempts to modify system configurations. references: - - https://www.cisa.gov/news-events/cybersecurity-advisories/aa20-266a -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://www.cisa.gov/news-events/cybersecurity-advisories/aa20-266a +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/lotus_blossom_chrysalis_backdoor.yml b/stories/lotus_blossom_chrysalis_backdoor.yml index 7caecba347a..a7cf2822a7b 100644 --- a/stories/lotus_blossom_chrysalis_backdoor.yml +++ b/stories/lotus_blossom_chrysalis_backdoor.yml @@ -1,7 +1,8 @@ name: Lotus Blossom Chrysalis Backdoor id: 4c58f09f-f76f-4261-bbf8-3be406d2fbad -version: 1 -date: '2026-02-03' +version: 2 +creation_date: '2026-03-16' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: | @@ -24,11 +25,10 @@ references: - https://www.rapid7.com/blog/post/tr-chrysalis-backdoor-dive-into-lotus-blossoms-toolkit/ - https://securelist.com/notepad-supply-chain-attack/118708/ - https://attack.mitre.org/groups/G0065/ -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/lumma_stealer.yml b/stories/lumma_stealer.yml index 09dfbad898d..70a25d6bb19 100644 --- a/stories/lumma_stealer.yml +++ b/stories/lumma_stealer.yml @@ -1,17 +1,12 @@ name: Lumma Stealer id: 6c8f76f6-1272-4c0e-afbd-5a9f58947fa5 -version: 1 -date: '2024-11-13' +version: 2 +creation_date: '2024-11-13' +modification_date: '2026-05-13' author: Michael Haag, Nasreddine Bencherchali, Splunk status: production description: Lumma Stealer is a sophisticated information-stealing malware that has been operating as a Malware-as-a-Service (MaaS) platform since 2022.

While legitimate Inno Setup binaries follow predictable installation patterns, malicious variants exhibit suspicious child process activity—such as launching cmd.exe, powershell.exe, or performing in-memory execution without dropping a visible payload. Analysts may observe payloads being written to temporary directories like %APPDATA%, %TEMP%, or %ProgramData%, followed by obfuscated execution mechanisms. Static analysis of the installer may reveal high-entropy sections, encrypted blobs, or anomalous script content embedded in the setup script.

It infiltrates systems through phishing emails, malicious downloads, or exploited vulnerabilities. Once inside, it encrypts files, appends specific extensions, and drops ransom notes with payment instructions. Medusa may also disable security tools, delete backups, and threaten to leak stolen data. Detection methods include monitoring unusual file encryption activity, identifying changes in file extensions, detecting unauthorized system modifications, and analyzing ransom notes. Advanced cybersecurity solutions use behavior-based detection, machine learning, and endpoint protection to identify and block Medusa ransomware before it executes. Regular updates, network monitoring, and employee awareness are crucial for preventing infections. narrative: The RaaS Medusa variant has been used to conduct ransomware attacks from 2021 to present. Medusa originally operated as a closed ransomware variant, meaning all development and associated operations were controlled by the same group of cyber threat actors. While Medusa has since progressed to using an affiliate model, important operations such as ransom negotiation are still centrally controlled by the developers. Both Medusa developers and affiliates—referred to as “Medusa actors”. Medusa is a ransomware-as-a-service (RaaS) variant first identified in June 2021. As of February 2025, Medusa developers and affiliates have impacted over 300 victims from a variety of critical infrastructure sectors with affected industries including medical, education, legal, insurance, technology, and manufacturing. The Medusa ransomware variant is unrelated to the MedusaLocker variant and the Medusa mobile malware variant per the FBI’s investigation. FBI, CISA, and MS-ISAC encourage organizations to implement the recommendations in the Mitigations section of this advisory to reduce the likelihood and impact of Medusa ransomware incidents. references: -- https://www.cisa.gov/news-events/cybersecurity-advisories/aa25-071a -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://www.cisa.gov/news-events/cybersecurity-advisories/aa25-071a +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/medusa_rootkit.yml b/stories/medusa_rootkit.yml index 303f12b31aa..5d025e0d574 100644 --- a/stories/medusa_rootkit.yml +++ b/stories/medusa_rootkit.yml @@ -1,18 +1,18 @@ name: Medusa Rootkit id: 9b63bd61-16e9-4adf-b40c-652706dfcd72 -version: 1 -status: production -date: '2025-08-05' +version: 2 +creation_date: '2025-08-06' +modification_date: '2026-05-13' author: Raven Tait, Splunk +status: production description: Medusa is a powerful, stealthy, versatile, and, modular rootkit designed to give attackers complete control over Linux systems.

Detected primarily through anomalous network activities, its behavior often involves outbound connections to command-and-control (C2) servers, encrypting and exfiltrating stolen credentials, financial data, and other personal information. Analysts have identified Meduza Stealer leveraging advanced evasion techniques, including dynamic obfuscation, anti-analysis methods, and the use of polymorphic code to bypass detection by traditional antivirus systems. Once deployed, it scans for browser-stored passwords, cryptocurrency wallets, and keylogging opportunities, potentially exploiting unpatched software vulnerabilities. Security tools flag it through heuristic detections, anomalous process executions, or unusual registry modifications. Meduza Stealer's malicious payloads are often distributed via phishing emails, malicious attachments, or trojanized software downloads. Effective defense requires a multi-layered security approach, regular software updates, and employee training to minimize risks posed by this potent cyber threat. narrative: Meduza Stealer is a relatively new entrant in the cybercrime landscape, first identified in early 2023. It quickly gained notoriety among threat actors for its effectiveness and adaptability. Designed as a data-stealing malware, it targets sensitive information such as login credentials, financial details, and cryptocurrency wallets. Its developers market it on underground forums, often touting its advanced features like dynamic obfuscation and anti-analysis mechanisms, making it difficult for traditional antivirus solutions to detect. Meduza Stealer typically spreads through phishing campaigns, malicious email attachments, and trojanized software downloads. Once executed, it infiltrates systems silently, harvesting data from web browsers, password managers, and clipboard activities. It then transmits the stolen information to its command-and-control (C2) servers using encrypted communication channels, further complicating detection and analysis. Security researchers have noted its use of polymorphic code, enabling it to modify its structure with each infection to evade heuristic and signature-based detection methods.Meduza Stealer highlights a growing trend in sophisticated, modular malware that appeals to cybercriminals due to its efficiency and ease of deployment. Effective mitigation strategies include adopting behavioral analysis tools, implementing robust endpoint security solutions, and maintaining user awareness through regular cybersecurity training.

Threat actors exploit a deserialization vulnerability in the WSUS AuthorizationCookie to achieve unauthenticated remote code execution on exposed WSUS servers. The attack leverages publicly accessible WSUS instances on default ports 8530/TCP (HTTP) and 8531/TCP (HTTPS) to send specially crafted POST requests that trigger deserialization attacks, resulting in shell spawning from the WSUS service and IIS worker processes. narrative: On October 23, 2025, Microsoft released an out-of-band security update for CVE-2025-59287, a critical deserialization vulnerability affecting Windows Server Update Services (WSUS). Security researchers at Huntress observed active exploitation starting around October 23, 2025 at 23:34 UTC, where threat actors targeted WSUS instances exposed to the internet on their default ports. The attack chain begins with the adversary sending multiple specially crafted HTTP POST requests to WSUS web service endpoints including /SimpleAuthWebService/SimpleAuth.asmx, /ClientWebService/Client.asmx, and /ReportingWebService/ReportingWebService.asmx. These requests exploit the deserialization vulnerability in the AuthorizationCookie parameter, allowing attackers to achieve unauthenticated remote code execution. Upon successful exploitation, the attack manifests in two distinct process execution chains - wsusservice.exe spawning cmd.exe which subsequently spawns PowerShell, and w3wp.exe (IIS worker process) following a similar pattern. The malicious PowerShell payload, delivered in base64-encoded format using the -ec parameter, executes reconnaissance commands including whoami, net user /domain for Active Directory enumeration, and ipconfig /all for network configuration discovery. The collected data is then exfiltrated to remote webhook services using either PowerShell's Invoke-WebRequest cmdlet with the PUT method or curl.exe with the --data-binary flag. Attackers have been observed using proxy networks to obfuscate their source infrastructure during exploitation attempts. Organizations should immediately apply Microsoft's security update, isolate WSUS servers from direct internet access, and restrict inbound traffic on ports 8530 and 8531 to only authorized management hosts and Microsoft Update servers. references: -- https://www.huntress.com/blog/exploitation-of-windows-server-update-services-remote-code-execution-vulnerability -- https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-59287 -- https://hawktrace.com/blog/CVE-2025-59287-UNAUTH -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection - cve: - - CVE-2025-59287 + - https://www.huntress.com/blog/exploitation-of-windows-server-update-services-remote-code-execution-vulnerability + - https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-59287 + - https://hawktrace.com/blog/CVE-2025-59287-UNAUTH +cve: + - CVE-2025-59287 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/monitor_for_updates.yml b/stories/monitor_for_updates.yml index 41923623901..123043a58c9 100644 --- a/stories/monitor_for_updates.yml +++ b/stories/monitor_for_updates.yml @@ -1,32 +1,22 @@ name: Monitor for Updates id: 9ef8d677-7b52-4213-a038-99cfc7acc2d8 -version: 1 -date: '2017-09-15' +version: 2 +creation_date: '2019-10-16' +modification_date: '2026-05-13' author: Rico Valdez, Splunk status: production -description: Monitor your enterprise to ensure that your endpoints are being patched - and updated.

NaiLaoLocker exhibits typical ransomware behavior, including multi-threaded file encryption using AES-256-CBC, appending a .locked extension to affected files, and dropping customized HTML ransom notes. However, it also includes several unique characteristics, it excludes system-critical files and directories from encryption to maintain host stability and uses SM2, a Chinese elliptic curve encryption standard, to secure the AES keys. The ransomware achieves execution via DLL side-loading, where a legitimate signed binary (usysdiag.exe) is abused to load a malicious DLL (sensapi.dll), which in turn decrypts and executes the core payload. Persistence and stealth are enhanced by mutex creation (Global\lockv7) to avoid re-execution, and the malware attempts to clean up after itself by deleting the loader DLL post-infection. NaiLaoLocker logs activity to a file (lock.log) in the ProgramData directory and makes encrypted files hidden. Analysts should look for unusual DLL loading behavior, AES-encrypted files with .locked extensions, and suspicious command-line or RDP usage in the environment. narrative: The campaign, discovered by Orange Cyberdefense and later analyzed by Fortinet, typically began with the exploitation of CVE-2024-24919, a critical vulnerability in Check Point VPN appliances. After gaining initial access, threat actors deployed post-exploitation tools and malware such as PlugX and ShadowPad before launching NaiLaoLocker in the final stage. The ransomware stands out due to its use of SM2 encryption, rarely seen outside of Chinese cryptographic implementations, and an embedded decryption routine — a feature unusual for ransomware and possibly indicative of a test or decoy build. Despite the presence of an SM2 private key, the decryption function is not operational with the hardcoded values, suggesting either incomplete development or intentional misdirection. This, along with the use of Chinese malware loaders and exploitation of a zero-day, suggests potential links to Chinese state-sponsored actors or at least actors mimicking their TTPs. NaiLaoLocker’s operational design and technical nuances imply it may serve multiple purposes — not only for financial extortion, but also to obscure espionage-related activity under the guise of ransomware. references: -- https://www.fortinet.com/blog/threat-research/nailaolocker-ransomware-cheese -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://www.fortinet.com/blog/threat-research/nailaolocker-ransomware-cheese +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/netsh_abuse.yml b/stories/netsh_abuse.yml index 128d4a00f0a..8aae5287fe7 100644 --- a/stories/netsh_abuse.yml +++ b/stories/netsh_abuse.yml @@ -1,30 +1,22 @@ name: Netsh Abuse id: 2b1800dd-92f9-47ec-a981-fdf1351e5f65 -version: 1 -date: '2017-01-05' +version: 2 +creation_date: '2019-10-16' +modification_date: '2026-05-13' author: Bhavin Patel, Splunk status: production -description: Detect activities and various techniques associated with the abuse of - `netsh.exe`, which can disable local firewall settings or set up a remote connection - to a host from an infected system. -narrative: 'It is a common practice for attackers of all types to leverage native - Windows tools and functionality to execute commands for malicious reasons.

Endpoint detection involves flagging the client32.exe executable running from unusual directories like Downloads or ProgramData instead of its standard Program Files location. Suspicious activity also encompasses renamed binaries with the internal name "client32" communicating with netsupportsoftware.com, or unauthenticated remote control sessions. Furthermore, monitoring for PowerShell execution associated with NetSupport Manager can reveal malicious deployment. These analytics help distinguish legitimate remote support from potential unauthorized access. narrative: NetSupport Manager, a legitimate remote access tool, often finds itself weaponized by adversaries, transforming into a Remote Access Trojan (RAT) for covert access. The narrative of its detection begins by understanding this duality while IT teams use it for benign support, threat actors exploit its capabilities, often via phishing or fake updates, to gain unauthorized control. The tell-tale signs emerge when this legitimate tool operates outside its normal parameters. For instance, observing client32.exe running from unusual directories like Downloads or ProgramData, rather than its secure Program Files location, immediately raises a red flag. Similarly, the presence of clear-text HTTP traffic containing CMD=ENCD commands, instead of the expected secure HTTPS, signals malicious intent. Furthermore, renamed binaries still internally identifying as "client32" communicating with netsupportsoftware.com, or unauthenticated remote control sessions, paint a clear picture of abuse. These anomalies, coupled with suspicious PowerShell execution, allow detection analytics to differentiate legitimate remote assistance from a stealthy intrusion, enabling defenders to uncover the adversary's presence references: - - https://www.linkedin.com/posts/mauricefielenbach_cybersecurity-incidentresponse-dfir-activity-7394805779448418304-g0gZ?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAuFTjIB5weY_kcyu4qp3kHbI4v49tO0zEk - - https://thedfirreport.com/2023/10/30/netsupport-intrusion-results-in-domain-compromise/ - - https://www.esentire.com/blog/evalusion-campaign-delivers-amatera-stealer-and-netsupport-rat -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://www.linkedin.com/posts/mauricefielenbach_cybersecurity-incidentresponse-dfir-activity-7394805779448418304-g0gZ?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAuFTjIB5weY_kcyu4qp3kHbI4v49tO0zEk + - https://thedfirreport.com/2023/10/30/netsupport-intrusion-results-in-domain-compromise/ + - https://www.esentire.com/blog/evalusion-campaign-delivers-amatera-stealer-and-netsupport-rat +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/network_discovery.yml b/stories/network_discovery.yml index 7d260e5bd3a..06f4f4ac469 100644 --- a/stories/network_discovery.yml +++ b/stories/network_discovery.yml @@ -1,23 +1,20 @@ name: Network Discovery id: af228995-f182-49d7-90b3-2a732944f00f -version: 1 -date: '2022-02-14' +version: 2 +creation_date: '2022-02-14' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production -description: Leverage searches that allow you to detect and investigate unusual activities - that might relate to the network discovery, including looking for network configuration, settings such as IP, MAC address, - firewall settings and many more. -narrative: Adversaries may use the information from System Network Configuration Discovery during automated discovery to shape follow-on behaviors, - including determining certain access within the target network and what actions to do next. +description: Leverage searches that allow you to detect and investigate unusual activities that might relate to the network discovery, including looking for network configuration, settings such as IP, MAC address, firewall settings and many more. +narrative: Adversaries may use the information from System Network Configuration Discovery during automated discovery to shape follow-on behaviors, including determining certain access within the target network and what actions to do next. references: -- https://attack.mitre.org/techniques/T1016/ -- https://www.welivesecurity.com/wp-content/uploads/2021/01/ESET_Kobalos.pdf -- https://researchcenter.paloaltonetworks.com/2018/09/unit42-xbash-combines-botnet-ransomware-coinmining-worm-targets-linux-windows/ -tags: - category: - - Malware - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://attack.mitre.org/techniques/T1016/ + - https://www.welivesecurity.com/wp-content/uploads/2021/01/ESET_Kobalos.pdf + - https://researchcenter.paloaltonetworks.com/2018/09/unit42-xbash-combines-botnet-ransomware-coinmining-worm-targets-linux-windows/ +category: + - Malware +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/njrat.yml b/stories/njrat.yml index 2f52c8e678c..9363b1f4cb9 100644 --- a/stories/njrat.yml +++ b/stories/njrat.yml @@ -1,26 +1,19 @@ name: NjRAT id: f6d52454-6cf3-4759-9627-5868a3e2b2b1 -version: 2 -date: '2023-09-07' +version: 3 +creation_date: '2023-09-13' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production -description: NjRat is a notorious remote access trojan (RAT) predominantly wielded by malicious operators to infiltrate and wield remote control over compromised systems. - This analytical story harnesses targeted search methodologies to uncover and investigate activities that could be indicative of NjRAT's presence. - These activities include tracking file write operations for dropped files, scrutinizing registry modifications aimed at establishing persistence mechanisms, - monitoring suspicious processes, self-deletion behaviors, browser credential parsing, firewall configuration alterations, spread itself via removable drive and an array of other potentially - malicious actions. -narrative: NjRat is also known as Bladabindi malware that was first discovered in the wild in 2012.

Discovered by NetSPI in 2023, this vulnerability capitalizes on the unchanged syncing capability of form objects, despite previous patches aimed at securing script code in custom forms. This technical blog delves into the discovery and weaponization of CVE-2024-21378, enhancing the Outlook penetration testing tool, Ruler, to exploit this flaw. A forthcoming pull request will provide a proof-of-concept code, aiding organizations in mitigating this security risk. narrative: CVE-2024-21378 is a weakness in Microsoft Outlook that lets hackers execute code remotely if they can authenticate themselves. Researchers at NetSPI found this issue in 2023. The problem started with a technique from 2017 by Etienne Stalmans at SensePost, who found a way to run code using VBScript in Outlook forms. Microsoft tried to fix it by only allowing approved script code in custom forms, but they didn't fix the main issue, which is how these forms sync. To exploit this vulnerability, you need to know how Outlook forms sync, using something called MAPI, and how they use certain properties and attachments when they're set up for the first time. Hackers can mess with these properties and attachments to run their own code. They do this by tricking the form's setup process, changing registry keys and files to get past Outlook's security. To show how this could be done, researchers modified Ruler, a tool for testing Outlook's security. They changed it so it could sync a harmful form with the right properties to run a specific type of file, a COM compliant native DLL. This not only showed that CVE-2024-21378 could be exploited but also that it could affect a lot of companies since so many use Microsoft Outlook. The discovery and the way it was exploited remind us that we always need to be on the lookout for security risks and work hard to protect against them. The cybersecurity world is always watching for the next big threat that could put our digital world at risk. As companies rush to fix this issue, it's a reminder of how important it is to stay ahead of these threats. references: -- https://www.netspi.com/blog/technical/red-team-operations/microsoft-outlook-remote-code-execution-cve-2024-21378/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection - cve: - - CVE-2024-21378 + - https://www.netspi.com/blog/technical/red-team-operations/microsoft-outlook-remote-code-execution-cve-2024-21378/ +cve: + - CVE-2024-21378 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/papercut_mf_ng_vulnerability.yml b/stories/papercut_mf_ng_vulnerability.yml index 5f2c746e720..39830bf48c6 100644 --- a/stories/papercut_mf_ng_vulnerability.yml +++ b/stories/papercut_mf_ng_vulnerability.yml @@ -1,32 +1,31 @@ name: PaperCut MF NG Vulnerability id: 2493d270-5665-4fb4-99c7-8f886f260676 -version: 1 -date: '2023-05-15' +version: 2 +creation_date: '2023-05-15' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: The FBI has issued a joint advisory concerning the exploitation of a PaperCut MF/NG vulnerability (CVE-2023-27350) by malicious actors, which began in mid-April 2023 and has been ongoing.

It then attempts to dismount volumes and overwrites critical NTFS structures and boot sector, with random data, leaving the system unbootable and data irrecoverable. narrative: PathWiper is a destructive malware campaign that surfaced during the conflict in Ukraine, designed with a single purpose, to render systems unusable. The operation begins quietly, leveraging a legitimate remote administration tool to deliver a malicious script (uacinstall.vbs). This script then drops and executes a disguised binary such as sha256sum.exe, masking its true intent. Once triggered, PathWiper systematically scans all available storage, including local drives, connected volumes, and even offline network shares. It dismounts volumes to bypass file locks and launches parallel threads to overwrite the very foundations of the NTFS file system—the master boot record, file table, logs, and boot sector. By corrupting these core structures with random data, PathWiper ensures that recovery is nearly impossible. Unlike earlier wipers, which indiscriminately destroyed data, PathWiper demonstrates a more deliberate approach, validating storage labels before carrying out its attack. This precision suggests a sophisticated adversary with both access and intent to maximize disruption. The campaign highlights how destructive malware can masquerade behind legitimate tools, evade casual detection, and inflict lasting operational damage on its targets. references: -- https://blog.talosintelligence.com/pathwiper-targets-ukraine/ -tags: - category: - - Data Destruction - - Malware - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://blog.talosintelligence.com/pathwiper-targets-ukraine/ +category: + - Data Destruction + - Malware + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/petitpotam_ntlm_relay_on_active_directory_certificate_services.yml b/stories/petitpotam_ntlm_relay_on_active_directory_certificate_services.yml index 1b8fe735fe7..4f15cc1149c 100644 --- a/stories/petitpotam_ntlm_relay_on_active_directory_certificate_services.yml +++ b/stories/petitpotam_ntlm_relay_on_active_directory_certificate_services.yml @@ -1,34 +1,24 @@ name: PetitPotam NTLM Relay on Active Directory Certificate Services id: 97aecafc-0a68-11ec-962f-acde48001122 -version: 1 -date: '2021-08-31' +version: 2 +creation_date: '2021-09-01' +modification_date: '2026-05-13' author: Michael Haag, Mauricio Velazco, Splunk status: production -description: PetitPotam (CVE-2021-36942,) is a vulnerablity identified in Microsofts - EFSRPC Protocol that can allow an unauthenticated account to escalate privileges - to domain administrator given the right circumstances. -narrative: In June 2021, security researchers at SpecterOps released a blog post and - white paper detailing several potential attack vectors against Active Directory - Certificated Services (ADCS).

Unlike traditional ransomware, PromptLock employs a locally hosted AI language model, specifically OpenAI's gpt-oss:20b, accessed via the Ollama API, to dynamically generate malicious Lua scripts in real time. These scripts are compatible across multiple platforms, including Windows, Linux, and macOS. During an infection, PromptLock autonomously determines which files to target for exfiltration or encryption based on predefined prompts, allowing it to adapt its behavior to the environment. The malware utilizes the SPECK 128-bit encryption algorithm and is written in Golang. While ESET considers PromptLock a proof of concept, its capabilities highlight the potential for AI to significantly enhance the sophistication and adaptability of ransomware attacks. narrative: In August 2025, ESET researchers uncovered PromptLock, a proof-of-concept ransomware that represents a new frontier in cyber threats. Unlike conventional ransomware, PromptLock leverages generative artificial intelligence to autonomously create malicious scripts tailored to its environment. Using a locally hosted AI language model accessed through the Ollama API, it generates Lua scripts on the fly, enabling it to adapt dynamically to different operating systems, including Windows, macOS, and Linux. The malware can identify and target files for encryption or exfiltration based on contextual prompts, demonstrating a level of adaptability previously unseen in ransomware. Written in Golang and employing SPECK 128-bit encryption, PromptLock exemplifies how AI can enhance both the sophistication and evasiveness of malicious software. While currently a proof of concept, its discovery underscores the emerging risk of AI-driven cyberattacks and highlights the need for vigilant, forward-looking cybersecurity measures. references: - - https://x.com/ESETresearch/status/1963209716684718315 - - https://arxiv.org/pdf/2508.20444 -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://x.com/ESETresearch/status/1963209716684718315 + - https://arxiv.org/pdf/2508.20444 +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/proxynotshell.yml b/stories/proxynotshell.yml index ac8d66c6665..02019dfb34d 100644 --- a/stories/proxynotshell.yml +++ b/stories/proxynotshell.yml @@ -1,23 +1,23 @@ name: ProxyNotShell id: 4e3f17e7-9ed7-425d-a05e-b65464945836 -version: 1 -date: '2022-09-30' +version: 2 +creation_date: '2022-09-30' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: Two new zero day Microsoft Exchange vulnerabilities have been identified actively exploited in the wild - CVE-2022-41040 and CVE-2022-41082. narrative: Microsoft is investigating two reported zero-day vulnerabilities affecting Microsoft Exchange Server 2013, 2016, and 2019.

The binary creates a working directory under %TEMP% using the RP_<GUID> prefix, mounts an embedded ISO image through the Windows Virtual Disk API, and stages a malicious payload disguised as wermgr.exe. A distinctive hallmark of the exploit is creation of an NTFS alternate data stream named :WDFOO on that file. The PoC also writes EICAR-like content to trigger an on-access scan by MsMpEng.exe. + + To win the race, RoguePlanet uses opportunistic oplocks, directory junctions, and volume shadow copy paths. It opens handles against shadow-copy-resolved paths such as ...\wermgr.exe:WDFOO, requests oplocks, and coordinates file supersede and rename operations while Defender is actively scanning the staged content. A named pipe at \\.\pipe\RoguePlanet is used to synchronize the final SYSTEM-context stage. When the race succeeds, the elevated instance launches an interactive console in the originating user session. + + From a detection standpoint, the most durable observables are Sysmon Event ID 15 records showing :WDFOO alternate data streams on wermgr.exe under RP_* temp directories, MsMpEng.exe touching those same paths, and the initial RoguePlanet.exe process writing ADS content. Secondary signals include creation of RP_* directories, virtual disk attach activity, reparse-point manipulation, and a user-context process later spawning SYSTEM-integrity children. + + ShieldBreak is a related proof-of-concept published by NightmareEclipse that exploits the same underlying weakness in Defender's scanning pipeline, targeting Windows Server 2025 rather than client builds. A low-privileged executable creates a working directory under C:\ShieldBreak_{GUID}\, registers a fake cloud storage provider, and creates a cloud file placeholder named BERLIN with a stream ADS. It loads mpclient.dll, Defender's own client API library, and directs Defender to scan a path resolved through the object manager under \BaseNamedObjects\Restricted\, hydrating the placeholder on demand. + + ShieldBreak wins its race through symbolic link manipulation rather than oplocks: an object-manager symlink initially resolves the scan target to the working directory, then is swapped to resolve through a CLFS path so that a locked Defender artifact file (BERLIN.blf) is produced instead. A second symbolic link, created over a local administrative share targeting 127.0.0.1, redirects that locked file to \Windows\System32\phoneinfo.dll, so the subsequent hydration writes the attacker's payload directly into a privileged system directory. The exploit then fabricates a Windows Error Report under the WER ReportQueue directory and manually executes the QueueReporting scheduled task, causing wermgr.exe to load phoneinfo.dll -- a classic phantom-DLL hijack target -- which steals a SYSTEM token and spawns an elevated shell. + + This analytic story groups detections that surface alternate data stream abuse, suspicious Defender-adjacent file and module-load activity, Windows Error Reporting abuse, and privilege escalation patterns consistent with RoguePlanet, ShieldBreak, and similar Windows Defender bypass research. Security teams should treat any matching activity as high priority, validate patch and Defender configuration status, and isolate affected endpoints pending vendor guidance. +references: + - https://github.com/MSNightmare/RoguePlanet/tree/main + - https://attack.mitre.org/techniques/T1068/ + - https://attack.mitre.org/techniques/T1564/004/ + - https://attack.mitre.org/techniques/T1211/ + - https://car.mitre.org/analytics/CAR-2020-08-001/ + - https://www.cyderes.com/howler-cell/rogueplanet-windows-zero-day + - https://www.picussecurity.com/resource/blog/rogueplanet-anatomy-of-the-nightmare-eclipse-microsoft-defender-zero-day#from-rce-to-lpe:-the-smb-and-vhdx-origin-story + - https://www.threatlocker.com/blog/nightmareeclipse-releases-new-poc-shieldbreak-exploits-same-weakness-as-rogueplanet + - https://www.hexacorn.com/blog/2016/06/02/beyond-good-ol-run-key-part-40/ + - https://secret.club/2020/07/01/diagtrack.html +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/router_and_infrastructure_security.yml b/stories/router_and_infrastructure_security.yml index f24e6c02fa4..6edd6f10ca2 100644 --- a/stories/router_and_infrastructure_security.yml +++ b/stories/router_and_infrastructure_security.yml @@ -1,30 +1,21 @@ name: Router and Infrastructure Security id: 91c676cf-0b23-438d-abee-f6335e177e77 -version: 1 -date: '2017-09-12' +version: 2 +creation_date: '2019-10-16' +modification_date: '2026-05-13' author: Bhavin Patel, Splunk status: production -description: Validate the security configuration of network infrastructure and verify - that only authorized users and systems are accessing critical assets.

The group gained notoriety following their September 2025 attack on Jaguar Land Rover, causing three weeks of production shutdown and £50M+ weekly losses. narrative: Scattered Lapsus$ Hunters represents a dangerous collaboration between Scattered Spider (UNC3944), Lapsus$, and Shiny Hunters - three threat actor groups that combine sophisticated social engineering expertise with advanced technical capabilities. Their September 2025 cyberattack on Jaguar Land Rover demonstrated the catastrophic potential of targeting critical supply chain infrastructure, resulting in a three-week production shutdown, tens of millions in weekly losses, and thousands of jobs at risk across the automotive supply chain. The group's attack methodology begins with sophisticated initial access through voice phishing (vishing), SMS phishing (smishing), and SIM swapping to compromise credentials and bypass multi-factor authentication. They employ advanced MFA bypass techniques including MFA fatigue attacks through repeated push notifications, SIM swapping to intercept SMS codes, and adversary-in-the-middle attacks on authentication flows. Once inside a network, they leverage legitimate remote management tools (AnyDesk, TeamViewer, ScreenConnect) to maintain persistence and evade detection, following a living-off-the-land approach that minimizes custom malware. For credential access, the group employs tools like Mimikatz for credential dumping, targets LSASS memory, extracts browser-stored credentials, and steals OAuth tokens and session cookies. They excel at lateral movement using RDP, Pass-the-Hash and Pass-the-Ticket techniques, and internal spearphishing. The group demonstrates deep understanding of cloud environments, targeting Azure AD, AWS, GCP, and O365 with techniques to disable MFA, create privileged accounts, assign administrative roles to service principals, and modify authentication policies. Data exfiltration occurs through cloud storage services (MEGA, Google Drive), file sharing platforms, and custom exfiltration channels. The impact phase includes stopping critical services, deploying ransomware, system shutdowns to maximize disruption, and data destruction. Previous notable attacks attributed to the constituent groups include Lapsus$ breaches of Microsoft, Nvidia, Okta, Samsung, and Ubisoft (2022), and Scattered Spider attacks on MGM Resorts and Caesars Entertainment (2023). The group targets telecommunications, retail, technology, manufacturing, and critical infrastructure sectors. Organizations should implement phishing-resistant MFA (FIDO2/WebAuthn), monitor RMM tool deployment, enable comprehensive logging, deploy EDR solutions, train employees on advanced social engineering tactics, segment critical production systems, and maintain offline backups of critical data. The detections in this analytic story cover the full attack lifecycle including MFA manipulation, unauthorized remote access software, credential theft, session hijacking, privilege escalation, defense evasion, data exfiltration, and production system disruption. references: -- https://www.wired.com/story/jlr-jaguar-land-rover-cyberattack-supply-chain-disaster/ -- https://wpsites.ucalgary.ca/jacobson-cpsc/2025/10/02/inside-the-jaguar-land-rover-cyberattack/ -- https://claroty.com/blog/5-security-takeaways-from-the-jaguar-land-rover-cyberattack -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://www.wired.com/story/jlr-jaguar-land-rover-cyberattack-supply-chain-disaster/ + - https://wpsites.ucalgary.ca/jacobson-cpsc/2025/10/02/inside-the-jaguar-land-rover-cyberattack/ + - https://claroty.com/blog/5-security-takeaways-from-the-jaguar-land-rover-cyberattack +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/scattered_spider.yml b/stories/scattered_spider.yml index 6cc86e1c6b5..e0b41e4c672 100644 --- a/stories/scattered_spider.yml +++ b/stories/scattered_spider.yml @@ -1,46 +1,28 @@ name: Scattered Spider id: 3df97513-d898-4168-927a-ed3595d6ea41 -version: 2 -status: production -date: '2026-01-22' +version: 3 +creation_date: '2025-07-31' +modification_date: '2026-05-13' author: Michael Haag, Splunk +status: production description: > - Detects tactics, techniques, and procedures (TTPs) associated with Scattered Spider (UNC3944, Octo Tempest, Storm-0875), - a sophisticated cybercriminal group targeting large enterprises through advanced social engineering and legitimate tool abuse. - This analytic story provides comprehensive detection coverage for their complete attack chain, from initial social engineering - campaigns through data exfiltration and ransomware deployment.

This analytic story is designed to detect possible mitre attack tatics and technique related to SnappyBee malware. narrative: SnappyBee emerged as a highly evasive malware designed for data theft and espionage. Initially spotted in targeted phishing campaigns, it quickly gained notoriety for its stealth and adaptability. Cybersecurity researchers found that SnappyBee disguises itself as legitimate software, infecting systems through malicious email attachments, compromised websites, and software cracks. Once activated, it burrows deep into the system, modifying registries and injecting code into trusted processes to remain undetected. Advanced evasion techniques, such as polymorphic encryption and sandbox detection, make traditional signature-based security ineffective. SnappyBee’s primary goal is to steal credentials, keystrokes, and network data, transmitting them to remote attackers. Continuous monitoring and proactive threat intelligence remain crucial to counter this evolving cyber menace. references: -- https://www.trendmicro.com/en_nl/research/24/k/earth-estries.html -tags: - category: - - Data Destruction - - Malware - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://www.trendmicro.com/en_nl/research/24/k/earth-estries.html +category: + - Data Destruction + - Malware + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/sneaky_active_directory_persistence_tricks.yml b/stories/sneaky_active_directory_persistence_tricks.yml index e89a019084c..f69d788dab6 100644 --- a/stories/sneaky_active_directory_persistence_tricks.yml +++ b/stories/sneaky_active_directory_persistence_tricks.yml @@ -1,37 +1,27 @@ name: Sneaky Active Directory Persistence Tricks id: f676c4c1-c769-4ecb-9611-5fd85b497c56 -version: 2 -date: '2024-03-14' +version: 3 +creation_date: '2022-08-29' +modification_date: '2026-05-13' author: Dean Luxton, Mauricio Velazco, Splunk status: production -description: Monitor for activities and techniques associated with Windows Active Directory persistence techniques. -narrative: Persistence consists of techniques that adversaries use to keep access to systems across restarts, changed credentials, and other interruptions that could cut off their access. - Active Directory is a centralized and hierarchical database that stores information about users, computers, and other resources on a network.

StealC abuses browser SQLite databases and encryption APIs to decrypt stored passwords, enabling account takeover and further compromise. The malware often runs silently in user context, evading detection through minimal footprint, obfuscation, and rapid data exfiltration to command-and-control servers. Detection typically involves monitoring unauthorized access to browser profile directories, suspicious process behavior interacting with browser credential stores, and outbound network traffic to known StealC infrastructure. narrative: StealC emerged as a malware-as-a-service information stealer designed to provide cybercriminals with an easy and low-cost way to harvest sensitive user data. First observed in the wild in the early 2020s, specifically in 2023, it gained popularity due to its simplicity, reliability, and focus on browser-stored information. StealC primarily targets credentials, cookies, and session data from widely used browsers, enabling account hijacking and follow-on attacks.

This technique involves modifying the Dll and FuncName Registry values that point to the dynamic link library (DLL) providing a SIP's function, which retrieves an encoded digital certificate from a signed file. By pointing to a maliciously-crafted DLL with an exported function that always returns a known good signature value, an adversary can apply an acceptable signature value to all files using that SIP. This can also enable persistent code execution, since these malicious components may be invoked by any application that performs code signing or signature validation. narrative: In user mode, Windows Authenticode digital signatures are used to verify a file's origin and integrity, variables that may be used to establish trust in signed code. The signature validation process is handled via the WinVerifyTrust application programming interface (API) function, which accepts an inquiry and coordinates with the appropriate trust provider, which is responsible for validating parameters of a signature. Because of the varying executable file types and corresponding signature formats, Microsoft created software components called Subject Interface Packages (SIPs) to provide a layer of abstraction between API functions and files. SIPs are responsible for enabling API functions to create, retrieve, calculate, and verify signatures. Unique SIPs exist for most file formats and are identified by globally unique identifiers (GUIDs). Adversaries may hijack SIP and trust provider components to mislead operating system and application control tools to classify malicious (or any) code as signed. -references: - - https://attack.mitre.org/techniques/T1553/003/ - - https://github.com/SigmaHQ/sigma/blob/master/rules/windows/registry/registry_set/registry_set_sip_persistence.yml - - https://specterops.io/wp-content/uploads/sites/3/2022/06/SpecterOps_Subverting_Trust_in_Windows.pdf - - https://github.com/gtworek/PSBits/tree/master/SIP - - https://github.com/mattifestation/PoCSubjectInterfacePackage - - https://pentestlab.blog/2017/11/06/hijacking-digital-signatures/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection +references: + - https://attack.mitre.org/techniques/T1553/003/ + - https://github.com/SigmaHQ/sigma/blob/master/rules/windows/registry/registry_set/registry_set_sip_persistence.yml + - https://specterops.io/wp-content/uploads/sites/3/2022/06/SpecterOps_Subverting_Trust_in_Windows.pdf + - https://github.com/gtworek/PSBits/tree/master/SIP + - https://github.com/mattifestation/PoCSubjectInterfacePackage + - https://pentestlab.blog/2017/11/06/hijacking-digital-signatures/ +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/suspicious_aws_bedrock_claude_activities.yml b/stories/suspicious_aws_bedrock_claude_activities.yml new file mode 100644 index 00000000000..90940a5a5b1 --- /dev/null +++ b/stories/suspicious_aws_bedrock_claude_activities.yml @@ -0,0 +1,20 @@ +name: Suspicious AWS Bedrock Claude Activities +id: c155d248-406d-48c7-9dd4-1c35607242e0 +creation_date: '2026-07-06' +modification_date: '2026-07-06' +version: 1 +author: Rod Soto, Splunk +status: production +description: This analytic story provides detection coverage for prompt injection, jailbreak attempts and other suspicious activities targeting AWS Bedrock Claude AI services.

VoidLink is a sophisticated, modular C2 framework written in Zig that targets cloud and containerized infrastructure with 30+ plugins, multiple rootkit capabilities (LD_PRELOAD, LKM, eBPF), and adaptive evasion mechanisms. The framework demonstrates commercial-grade development with Chinese-affiliated origins and is designed for long-term persistence, credential theft, and data exfiltration in AWS, GCP, Azure, Alibaba, and Tencent cloud environments. Monitor for cloud metadata service abuse, container escape attempts, systemd/cron persistence, LD_PRELOAD hijacking, kernel module loading, SSH lateral movement, and Linux-specific defense evasion techniques including log tampering and rootkit deployment. VoidLink's plugin-based architecture and cloud-first tradecraft make it particularly dangerous in modern containerized and Kubernetes environments. narrative: VoidLink represents a significant evolution in Linux malware targeting cloud-native infrastructure. Discovered by Check Point Research in December 2025, this framework showcases advanced capabilities specifically designed for cloud and container environments. The malware can detect which cloud provider it's running on (AWS, GCP, Azure, Alibaba, Tencent), identify if it's in a Docker container or Kubernetes pod, and adjust its behavior accordingly. VoidLink's modular plugin system, inspired by Cobalt Strike's Beacon Object Files (BOF), allows operators to dynamically load over 30 specialized modules at runtime for reconnaissance, credential access, persistence, privilege escalation, and data exfiltration. The framework employs multiple rootkit mechanisms including user-mode LD_PRELOAD hijacking, kernel-level LKM rootkits, and modern eBPF-based hiding techniques. Its command and control infrastructure supports HTTP/HTTPS, DNS tunneling, ICMP tunneling, and P2P mesh communication between compromised hosts. VoidLink's operational security features include runtime code encryption, self-deletion upon tampering detection, and adaptive evasion that modifies behavior based on detected security products. The framework's cloud-first design includes dedicated modules for cloud metadata harvesting, container secret extraction, Kubernetes privilege escalation, and automated credential theft from cloud environments. Detection requires comprehensive visibility across Linux endpoints, container runtimes, Kubernetes audit logs, and cloud provider activity logs. Key detection opportunities include monitoring for cloud metadata service access (169.254.169.254), systemd service file creation, cron job manipulation, LD_PRELOAD environment variable usage, kernel module loading, SSH key modifications, and suspicious process execution patterns within containers. Organizations running containerized workloads in cloud environments should prioritize detection of container escape attempts, Kubernetes RBAC abuse, and cloud credential theft as VoidLink specifically targets these attack vectors for initial access and privilege escalation. references: -- https://research.checkpoint.com/2026/voidlink-the-cloud-native-malware-framework/ -- https://attack.mitre.org/techniques/T1574/006/ -- https://attack.mitre.org/techniques/T1053/006/ -- https://attack.mitre.org/techniques/T1611/ -- https://attack.mitre.org/techniques/T1552/005/ -- https://attack.mitre.org/techniques/T1014/ -tags: - category: - - Malware - - Cloud Security - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://research.checkpoint.com/2026/voidlink-the-cloud-native-malware-framework/ + - https://attack.mitre.org/techniques/T1574/006/ + - https://attack.mitre.org/techniques/T1053/006/ + - https://attack.mitre.org/techniques/T1611/ + - https://attack.mitre.org/techniques/T1552/005/ + - https://attack.mitre.org/techniques/T1014/ +category: + - Malware + - Cloud Security +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/volt_typhoon.yml b/stories/volt_typhoon.yml index 495436b753f..3abd1a9382e 100644 --- a/stories/volt_typhoon.yml +++ b/stories/volt_typhoon.yml @@ -1,30 +1,28 @@ name: Volt Typhoon id: f73010e4-49eb-44ef-9f3f-2c25a1ae5415 -version: 1 -date: '2023-05-25' +version: 2 +creation_date: '2023-05-25' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production description: This analytic story contains detections that allow security analysts to detect and investigate unusual activities that might relate to the "Volt Typhoon" group targeting critical infrastructure organizations in United States and Guam.

Authentication certificates can be both stolen and forged. For example, AD CS certificates can be stolen from encrypted storage (in the Registry or files), misplaced certificate files (i.e. Unsecured Credentials), or directly from the Windows certificate store via various crypto APIs.With appropriate enrollment rights, users and/or machines within a domain can also request and/or manually renew certificates from enterprise certificate authorities (CA). This enrollment process defines various settings and permissions associated with the certificate. Abusing certificates for authentication credentials may enable other behaviors such as Lateral Movement. Certificate-related misconfigurations may also enable opportunities for Privilege Escalation, by way of allowing users to impersonate or assume privileged accounts or permissions via the identities (SANs) associated with a certificate. These abuses may also enable Persistence via stealing or forging certificates that can be used as Valid Accounts for the duration of the certificate's validity, despite user password resets. Authentication certificates can also be stolen and forged for machine accounts.

This response would flow through to the client's local DNS server, which if not patched for CVE-2020-1350, would cause the buffer overflow. The detection searches in this Analytic Story use wire data to detect the malicious behavior. Searches for Splunk Stream and Zeek are included. The Splunk Stream search correlates across stream:dns and stream:tcp, while the Zeek search correlates across bro:dns:json and bro:conn:json. These correlations are required to pick up both the DNS record types (SIG and KEY) along with the payload size (>65KB). references: -- https://research.checkpoint.com/2020/resolving-your-way-into-domain-admin-exploiting-a-17-year-old-bug-in-windows-dns-servers/ -- https://support.microsoft.com/en-au/help/4569509/windows-dns-server-remote-code-execution-vulnerability -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection + - https://research.checkpoint.com/2020/resolving-your-way-into-domain-admin-exploiting-a-17-year-old-bug-in-windows-dns-servers/ + - https://support.microsoft.com/en-au/help/4569509/windows-dns-server-remote-code-execution-vulnerability +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/windows_drivers.yml b/stories/windows_drivers.yml index 64313d67de9..a71cd93e279 100644 --- a/stories/windows_drivers.yml +++ b/stories/windows_drivers.yml @@ -1,25 +1,22 @@ name: Windows Drivers id: d0a9323f-9411-4da6-86b2-18c184d750c0 -version: 1 -date: '2022-03-30' +version: 2 +creation_date: '2022-04-22' +modification_date: '2026-05-13' author: Michael Haag, Splunk status: production description: Adversaries may use rootkits to hide the presence of programs, files, network connections, services, drivers, and other system components. -narrative: A rootkit on Windows may sometimes be in the form of a Windows Driver.

When a user connects to a system using the native RDP client (mstsc.exe), Windows creates several files that can later be used as forensic evidence. These include Default.rdp in the user’s Documents folder, which stores recent connection details such as the last server accessed and user preferences, as well as bitmap cache files (*.bmc, cache*.bin) in the Terminal Server Client cache directory, which can contain fragments of the remote system’s graphical environment. Together, these artifacts help investigators confirm that RDP activity occurred, identify which hosts were accessed, and sometimes even reconstruct portions of what the attacker saw on screen. Because of their forensic value, attackers often attempt to remove them. Common evasion methods include manually deleting the files, running cleanup scripts, disabling RDP caching features, or using non-standard RDP clients that do not generate artifacts. This detection looks for signs of RDP usage followed by suspicious cleanup activity, surfacing post-access OPSEC behavior that frequently precedes or accompanies lateral movement, privilege escalation, or data theft. Detecting this pattern is key to exposing stealthy attacker behavior in interactive intrusions. references: -- https://medium.com/@bonguides25/how-to-clear-rdp-connections-history-in-windows-cf0ffb67f344 -- https://thelocalh0st.github.io/posts/rdp/ -tags: - category: - - Adversary Tactics - product: - - Splunk Enterprise - - Splunk Enterprise Security - - Splunk Cloud - usecase: Advanced Threat Detection \ No newline at end of file + - https://medium.com/@bonguides25/how-to-clear-rdp-connections-history-in-windows-cf0ffb67f344 + - https://thelocalh0st.github.io/posts/rdp/ +category: + - Adversary Tactics +product: + - Splunk Enterprise + - Splunk Enterprise Security + - Splunk Cloud +usecase: Advanced Threat Detection diff --git a/stories/windows_registry_abuse.yml b/stories/windows_registry_abuse.yml index 9d7c90ceb5c..a4e3cc342a1 100644 --- a/stories/windows_registry_abuse.yml +++ b/stories/windows_registry_abuse.yml @@ -1,27 +1,19 @@ name: Windows Registry Abuse id: 78df1df1-25f1-4387-90f9-c4ea31ce6b75 -version: 1 -date: '2022-03-17' +version: 2 +creation_date: '2022-03-17' +modification_date: '2026-05-13' author: Teoderick Contreras, Splunk status: production -description: Windows services are often used by attackers for persistence, privilege escalation, - lateral movement, defense evasion, collection of data, a tool for recon, credential dumping and - payload impact.

Rapid7 has observed active exploitation of these vulnerabilities. Affected versions are prior to 8.7.4 and 8.8.2. Immediate action is advised - upgrade to WS_FTP Server version 8.8.2. For those unable to update, disabling the Ad Hoc Transfer module is suggested as a temporary measure. This comes in the wake of increased scrutiny following the Cl0p ransomware attack on MOVEit Transfer in May 2023. narrative: Two critical vulnerabilities have been identified in WS_FTP Server, a widely-used secure file transfer solution. The first, CVE-2023-40044, is a .NET deserialization flaw that targets the Ad Hoc Transfer module of WS_FTP Server versions earlier than 8.7.4 and 8.8.2. This flaw allows an attacker to execute arbitrary commands on the server's operating system without needing authentication. The second vulnerability, CVE-2023-42657, is a directory traversal flaw that allows attackers to perform unauthorized file operations outside of their authorized WS_FTP folder. In severe cases, the attacker could escape the WS_FTP Server file structure and perform operations on the underlying operating system. Both vulnerabilities have been observed being exploited in the wild and immediate action for mitigation is strongly advised. Updating to WS_FTP Server version 8.8.2 is recommended.
