This rule detects the creation of a scheduled task named 'GlobalProtectVPNUpdate' using schtasks.exe, which has been identified as a technique used to facilitate the execution of malicious payloads masquerading as legitimate GlobalProtect VPN components. It also monitors for the subsequent execution of 'GlobalProtect.exe' when initiated by Windows background services like taskeng.exe or svchost.exe, which is indicative of persistence and unauthorized code execution.
Detects the creation of scheduled tasks using the 'schtasks.exe' utility that reference suspicious paths (AppData/Local or Roaming) or specific executables often associated with suspicious activity (Launcher.exe, GapiUpdate.exe) in conjunction with 'DeviceSetupManager'. Additionally, it includes a hash-based detection for a specific known malicious file artifact.

Additionally, it includes a hash-based detection for a specific known malicious file artifact.
Detects the creation of a scheduled task using schtasks.exe or reg.exe that is configured to run at system logon (/sc onlogon) using potentially malicious or persistence-related filenames such as client32.exe or NSM789508.
Detects the creation of a scheduled task using schtasks.exe or reg.exe that is configured to run at system logon (/sc onlogon) using potentially malicious or persistence-related filenames such as client32.exe or NSM789508.
Detects the creation of a scheduled task using 'schtasks.exe' where the initiating process is a script interpreter such as 'mshta.exe' or 'powershell.exe'. This behavior is often associated with the execution of malicious payloads or the establishment of persistence.
Detects evidence of persistence mechanisms associated with the StyleSmuggler implant. The rule monitors for malicious crontab entries and file system activity related to gvfsd-user, .gvfsd, and /tmp/.kw_ artifacts.
This rule detects the use of the LockAppHost process to execute suspicious commands associated with tampering with security configurations, including Windows Defender settings, service management (sc.exe), and task scheduling. Adversaries may abuse this process to bypass security controls, disable real-time monitoring, or maintain persistence.
This rule monitors for potential persistence and malicious activity by aggregating three distinct detection signals: COM hijacking attempts via the InprocServer32 registry key, the creation of scheduled tasks using specific suspicious naming conventions, and the identification of named mutexes indicative of specific malware presence.
Detects the creation of scheduled tasks using the 'schtasks.exe' utility, a technique often used by the CRPx0 ransomware to establish persistence on a system. The rule specifically monitors for the '/create' command-line argument while excluding common, benign updater processes such as those from Microsoft Edge, Google, and OneDrive.
Detects the creation or modification of crontab files, as well as the execution of crontab commands, that involve suspicious paths (e.g., /tmp, /var/tmp, /dev/shm, hidden files) or command obfuscation techniques such as base64 encoding. This behavior is often associated with the establishment of persistence by adversaries.
This rule detects the use of the LockAppHost process to execute suspicious commands associated with tampering with security configurations, including Windows Defender settings, service management (sc.exe), and task scheduling. Adversaries may abuse this process to bypass security controls, disable real-time monitoring, or maintain persistence.
Detects the creation of a scheduled task named 'Windows Update ALPHV' using the schtasks.exe utility. This task is associated with the OpnKey ransomware, which uses this name to masquerade as a legitimate Windows Update task while running with SYSTEM privileges to maintain persistence.
Detects the creation of a scheduled task using schtasks.exe or reg.exe that is configured to run at system logon (/sc onlogon) using potentially malicious or persistence-related filenames such as client32.exe or NSM789508.

This rule detects the creation of scheduled tasks using names that masquerade as legitimate update services for Microsoft Edge, OneDrive, or Windows. Adversaries often use these names to hide persistence mechanisms within the Task Scheduler to maintain system access.

Detects direct unauthorized modifications to Linux crontab files or the addition of specific known malicious cron job patterns. It specifically monitors for file changes in '/var/spool/cron' and correlates them with 'crontab -e' process executions to identify manual versus automated or malicious modifications. Additionally, it checks for specific hardcoded malicious patterns commonly associated with known threat activity.
