Detects the creation of a Windows scheduled task using 'schtasks.exe' with the 'Highest' run level, configured to execute either 'powershell.exe' or 'wscript.exe'. This pattern is consistent with persistence mechanisms observed in Operation Poisson, where attackers establish elevated, automated execution of scripts.

Detects the creation of scheduled tasks using schtasks.exe that point to high-risk directories (Temp, AppData, ProgramData) or utilize obfuscated PowerShell commands (encoded parameters). This behavior is often associated with adversary persistence or initial execution.

Detects the creation of suspicious cron jobs related to Node.js or npm processes, specifically looking for indicators of post-installation scripts or recurring tasks that might suggest malicious activity, such as supply chain compromise or persistence mechanisms.

Detects the creation of a scheduled task using 'schtasks.exe' with specific command-line arguments that indicate an attempt to establish persistence. The rule looks for 'schtasks.exe' creating a task named 'Runtime Broker' that executes a program from a suspicious path within 'C:\ProgramData\Microsoft\Windows\Runtime\'. This pattern is often used by adversaries to maintain access to a system.

This rule detects the creation or modification of scheduled tasks (EventID 4698 or 4699) where the command line for the task contains references to scripting languages like PowerShell, cmd, or VBScript. It then groups these events by computer and user, flagging if two or more such tasks are created by the same user on the same computer, which could indicate malicious activity.

This rule detects the creation of scheduled tasks using the 'schtasks.exe' utility with command-line arguments indicating persistence triggers ('onlogon', 'onstart') or elevation to the 'SYSTEM' account. Adversaries commonly use these methods to ensure malicious code executes automatically upon system startup or with high privileges to facilitate further exploitation.

This rule detects the creation of scheduled tasks using schtasks.exe that exhibit characteristics associated with the SharkLoader malware. Specifically, it identifies tasks using suspicious names like 'OneDrive Standalone Update Task' or those referencing components dropped in %APPDATA% directories (e.g., \xwreg\, \xgdf\), or tasks masquerading as 'SystemSettings.exe' or 'KasperskyLab' directories.

Detects the creation of scheduled tasks using schtasks.exe that exhibit suspicious characteristics. This includes tasks referencing external URLs, those containing base64-encoded or obfuscated command strings, and tasks pointing to binaries or scripts in user-writable paths (e.g., AppData, Temp). The rule specifically targets tasks intended to run with SYSTEM privileges or those using common persistence triggers, while excluding known legitimate administrative software.

Detects the creation of scheduled tasks named 'RageGuard' or utilizing 'win_guard' binary paths in suspicious directories (Temp, AppData, ProgramData), correlated with concurrent registry modifications to Winlogon (Shell/Userinit) or Image File Execution Options (Debugger) using the same binary, indicative of the TrymeLocker ransomware persistence mechanism.

Detects the creation of scheduled tasks using schtasks.exe that point to the ProgramData directory, which is a common persistence location for malware like SystemBC. The rule excludes common, benign software installers and updaters that frequently use this directory to avoid false positives.

Detects the creation of scheduled tasks (schtasks.exe) spawned by common scripting or social engineering-related parent processes (PowerShell, Cmd, WScript, MSHTA). The rule specifically looks for payloads associated with common attack patterns, such as downloading remote content or executing encoded commands, which indicates potential persistence or payload delivery activities.

Detects the creation of scheduled tasks using schtasks.exe where the task action executes a scripting engine or living-off-the-land binary (LOLBin). This behavior is often indicative of adversaries attempting to establish persistence or execute code using native system tools to evade detection.

Detects the creation of a LaunchAgent property list (.plist) file on macOS that uses a spoofed Apple namespace label (com.apple.system.services.activity). This behavior is characteristic of the Gaslight malware family attempting to establish persistence.

This rule detects the creation or modification of scheduled tasks using utilities like schtasks.exe or at.exe that are followed by the execution of script-based interpreters (PowerShell, CMD, or WScript). This pattern is commonly indicative of an attacker establishing persistence by scheduling malicious scripts to run automatically.

This rule detects potential persistence mechanisms and execution associated with Amadey or StealC malware. It identifies the creation of scheduled tasks (`schtasks.exe /create`) targeting suspicious directories or known Amadey/StealC paths, as well as Task Scheduler Event ID 4698 (task created) referencing these paths. Additionally, it looks for direct execution of 'nudwee.exe' (an Amadey component) and shell processes (`cmd.exe`, `powershell.exe`) spawned by scheduled tasks from suspicious locations or referencing Amadey/StealC paths.

Detects the creation of scheduled tasks using the 'schtasks' utility, initiated by suspicious parent processes (browsers, scripting engines, or common tools) or utilizing suspicious task actions (PowerShell, VBScript, etc.) in user-writable directories. Additionally, it flags tasks with high-frequency scheduling or persistence triggers paired with encoded or hidden command-line arguments, which are common indicators of malicious activity such as malware execution or persistence mechanisms.

Detects a post-compromise reconnaissance burst associated with BeepRAT, where a process running from a suspicious directory (AppData, Temp, or ProgramData) executes five or more system discovery commands within a 60-second window, following the creation of a scheduled task on the same host.

Detects the BeepRAT malware using the Tiny C Compiler (tcc.exe) to execute shellcode directly from memory. The rule identifies TCC execution from non-standard directories (specifically within %LOCALAPPDATA%\TCC) using specific flags (-nostdlib -run), and correlates this activity with the creation of an elevated scheduled task named 'WindowsUpdateTempFileCleanUp' used for persistence.

Detects suspicious command-line activity related to the abuse of Group Policy Objects, including unauthorized GPO creation/linking, modification of GPO registry settings, forced GPO updates, and the staging of files or scheduled tasks within NETLOGON or SYSVOL directories, commonly associated with ransomware deployment or domain persistence.
