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 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 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.
The rule detects correlation between the creation of persistence-related Registry keys (specifically Windows Run keys or Browser Native Messaging hosts) and the execution of the schtasks.exe utility to create or manage a task related to 'psychedelicloveUtils'. This pattern suggests an adversary attempting to maintain persistence by linking Registry-based autostart mechanisms with a scheduled task.

This pattern suggests an adversary attempting to maintain persistence by linking Registry-based autostart mechanisms with a scheduled task.
Detects persistence attempts using common Windows auto-start registry keys or scheduled tasks where the initiating process is unsigned or has an invalid signature. The rule focuses on binaries executing from suspicious, user-writable directories (e.g., Temp, AppData, Downloads) and specifically targets persistence mechanisms involving the 'SecurityHealthService.exe' filename.

Detects the creation of a Windows scheduled task via schtasks.exe where the initiating process is located in common user-writable temporary or non-standard directories (e.g., AppData, Temp, or Public folders). This behavior is often indicative of malicious persistence mechanisms being established by a dropper or stage-one malware payload.
Detects the creation of a Windows scheduled task via schtasks.exe where the initiating process is located in common user-writable temporary or non-standard directories (e.g., AppData, Temp, or Public folders). This behavior is often indicative of malicious persistence mechanisms being established by a dropper or stage-one malware payload.
Detects a behavioral chain where a process establishes persistence using a 'WindowsUpdate' Registry Run key or a scheduled task, followed within five minutes by an outbound network connection from the same process. The rule specifically excludes cases where a ZIP file was written to disk, identifying potential in-memory staging for exfiltration.
This rule detects potentially malicious activities involving the creation of suspicious scheduled tasks or the use of system binaries (rundll32.exe and control.exe) to execute commands, often associated with lateral movement or persistence. It looks for schtasks.exe commands creating tasks with specific deceptive names, and rundll32.exe or control.exe executing from remote network paths or suspicious command line arguments.
This rule detects potentially malicious activities involving the creation of suspicious scheduled tasks or the use of system binaries (rundll32.exe and control.exe) to execute commands, often associated with lateral movement or persistence. It looks for schtasks.exe commands creating tasks with specific deceptive names, and rundll32.exe or control.exe executing from remote network paths or suspicious command line arguments.
This rule detects potential persistence via scheduled tasks that masquerade as legitimate network components (e.g., 'System Health Monitor'), as well as abnormal use of WebDav via rundll32.exe or net.exe in the context of the Star Blizzard (COLDRIVER) campaign. It monitors for task creation/updates, schtasks command lines, registry artifacts related to task scheduling, and suspicious WebDav network utility usage, while excluding common security tool processes.
Detects the creation of scheduled tasks using 'schtasks.exe' or 'Register-ScheduledTask' where the task command path is located in suspicious directories such as AppData, Temp, or ProgramData, or where the task is configured to run under the SYSTEM account. This behavior is commonly used by adversaries for persistence.
Detects the creation of scheduled tasks using schtasks.exe that exhibit behaviors associated with common remote execution tools (e.g., Impacket's atexec.py) or staging from insecure directories like Temp, ProgramData, or network shares. These patterns are frequently used by threat actors, including INC Ransom, for lateral movement and remote execution of malicious payloads.
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.
This rule monitors for suspicious persistence mechanisms associated with 'Agta Backup' software, specifically looking for the creation of new Windows services, the addition of scheduled tasks, and the manipulation of processes related to 'Credential Guard.exe' within Agta Backup directories. It also tracks the presence of specific file artifacts within the application's install directories, which could indicate unauthorized installation or persistence attempts.
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.
