Detects the creation of scheduled tasks using the 'schtasks.exe' utility where the command line contains suspicious patterns such as execution of common scripting engines (PowerShell, wscript, cscript), use of common staging directories (temp, appdata, programdata), or naming conventions that mimic legitimate Windows system tasks.
Detects the creation of scheduled tasks using the 'schtasks.exe' utility where the command line contains suspicious patterns such as execution of common scripting engines (PowerShell, wscript, cscript), use of common staging directories (temp, appdata, programdata), or naming conventions that mimic legitimate Windows system tasks.
Detects the creation of scheduled tasks using the 'schtasks.exe' utility with either system-level privileges ('/ru SYSTEM') or persistent triggers ('/sc onlogon' or '/sc onstart'). The rule filters out commonly trusted parent processes, highlighting potential persistence mechanisms established by unauthorized or unusual processes.
Detects the creation of scheduled tasks (via Event ID 4698 or schtasks.exe) involving suspicious action paths, encoded PowerShell commands, LOLBins, or tasks configured to run as SYSTEM by non-administrator users, which is a common persistence mechanism for malware.
Detects the creation of scheduled tasks using Event ID 4698 or command-line execution of schtasks.exe. The rule specifically looks for tasks created in suspicious paths such as AppData or ProgramData, or tasks configured to run with highest privileges and/or marked as hidden, which are common indicators of persistence mechanisms used by adversaries.
Detects the execution of native Windows utilities such as vssadmin, wmic, wbadmin, and bcdedit used to delete volume shadow copies, the backup catalog, or disable system recovery boot policies. This activity is a common precursor to ransomware encryption to prevent data restoration.
Detects the creation of scheduled tasks using the 'schtasks.exe' utility where the task is configured to run in the security context of the SYSTEM account or executes suspicious binaries like PowerShell, mshta, or other living-off-the-land binaries. This behavior is indicative of potential persistence mechanisms employed by adversaries.
Detects Microsoft Office applications or scripting engines spawning schtasks.exe to create or modify a scheduled task that executes as the SYSTEM user upon system startup or login. This behavior is highly indicative of persistence mechanisms used by malicious documents or scripts.
This rule detects persistence establishment via Scheduled Task creation shortly (within 15 minutes) after a suspicious PowerShell process execution. The PowerShell execution matches the 'ClickFix' pattern, characterized by hidden/bypass window styles and the invocation of remote download or execution cmdlets (e.g., IEX, IRM).
Detects the creation of scheduled tasks using schtasks.exe that involve suspicious arguments (such as encoded commands, execution from volatile directories like Temp/AppData, or run-once triggers) shortly after a file has been downloaded into a temporary or user-writable directory. This pattern is commonly indicative of an adversary establishing persistence for downloaded malware.
Detects the creation of scheduled tasks using schtasks.exe that execute common script interpreters (powershell.exe, wscript.exe, mshta.exe, cscript.exe) from user-writable or temporary directories (Temp, AppData, ProgramData, Users\Public). This activity often indicates an attempt to establish persistence or run malicious scripts.
Detects the execution of control.exe with suspicious command-line arguments involving WebDAV paths (DavWWWRoot) and file extensions like .cpl or .dll, initiated by Windows task-related processes (svchost, taskeng, schtasks). This pattern is indicative of potential malicious payload loading or proxy execution where a scheduled task is used to trigger a secondary malicious component.
Detects the execution of control.exe with suspicious command-line arguments involving WebDAV paths (DavWWWRoot) and file extensions like .cpl or .dll, initiated by Windows task-related processes (svchost, taskeng, schtasks). This pattern is indicative of potential malicious payload loading or proxy execution where a scheduled task is used to trigger a secondary malicious component.
Detects the execution of control.exe with suspicious command-line arguments involving WebDAV paths (DavWWWRoot) and file extensions like .cpl or .dll, initiated by Windows task-related processes (svchost, taskeng, schtasks). This pattern is indicative of potential malicious payload loading or proxy execution where a scheduled task is used to trigger a secondary malicious component.
Detects the creation of a scheduled task using 'schtasks.exe' that involves suspicious command-line patterns, specifically tasks pointing to potentially volatile directories (temp, appdata, programdata) or tasks executing PowerShell/CMD with common obfuscation/execution arguments such as encoded commands, hidden window styles, or base64 decoding.
Detects the creation of scheduled tasks, recurring jobs, or webhook subscriptions by a user identity flagged as an AI_AGENT. This activity is monitored for persistence, especially when the event lacks a descriptive context or targets external networks, suggesting potential unauthorized agent behavioral drift or malicious persistence.
Detects the manual enablement of network discovery services (fdrespub, fdPHost, SSDPSRV, upnphost) and the associated Windows Firewall rules. This activity is a known tactic used by Gentlemen ransomware to facilitate lateral movement and network share enumeration by making the compromised host visible to others and allowing it to discover peers.
Detects the creation of scheduled tasks using schtasks.exe or PowerShell cmdlets that execute with SYSTEM privileges, or tasks that reference common temporary directories or persistence triggers (logon, idle). This behavior is frequently associated with ransomware, malware persistence, or staged payload execution.
Detects the creation of a Windows scheduled task where the task name contains the string 'keyroll', often associated with credential rotation or suspicious persistence mechanisms.
Detects the VelvetCake malware installation and operational pattern, which utilizes a scheduled task named 'OneDriveUpdateScheduler' to execute PowerShell scripts ('update1.ps1' or 'update2.ps1'). These scripts periodically retrieve modules or payloads from external infrastructure, specifically hardcoded C2 IPs or a dedicated GitHub repository.
Detects the creation of a scheduled task intended to masquerade as 'MicrosoftEdgeUpdateTask' using either schtasks.exe or PowerShell. The rule specifically monitors for tasks being registered in AppData/Roaming directories, which is a common indicator of persistence by malicious actors attempting to mimic legitimate Microsoft Edge update processes.
