Detects the creation of a scheduled task named 'WindowsUpdateTempFileCleanUp' or suspicious scheduled task naming conventions associated with the BeepRAT malware. The rule specifically monitors for the execution of a TCC loader chain, often masquerading or leveraging configurations located within the %LOCALAPPDATA%\TCC directory to maintain persistence with high privileges.
Detects remote LSASS memory dumping using the built-in comsvcs.dll MiniDump functionality, invoked by rundll32.exe. This activity is consistent with tools like lsassy, which leverage techniques such as SMB service creation, WMI, scheduled tasks, and DCOM/MMC to execute the dump remotely. The rule monitors for command lines containing comsvcs.dll and MiniDump, targeting the LSASS process or staging files in the Windows Temp directory.
Detects the creation of scheduled tasks using the Windows schtasks utility where the task action points to a file located in common user-writable directories such as AppData, Temp, Users\Public, or Downloads. This behavior is frequently associated with persistence mechanisms used by malware and backdoors.

Detects the creation of scheduled tasks using schtasks.exe where the command originates from or references the C:\ProgramData\ directory. This pattern is consistent with the SystemBC (Coroxy) malware's persistence mechanism, where a randomly named executable is staged in ProgramData and configured for execution via Task Scheduler.
Detects the Payouts King malware creating, running, or deleting specific scheduled tasks named \Mozilla\UpdateTask or \Mozilla\ElevateTask, as well as indirect execution of these tasks via cmd.exe redirection.
Detects the creation of scheduled tasks (via schtasks.exe or at.exe) that include command-line arguments referencing virtualization artifacts (qemu, .qcow2, .vmdk, TPMProfiler) or specific database/dll files (vault.db, bisrv.dll). This pattern is often indicative of persistence mechanisms used by malware or threat actors to manage virtualized environments, exfiltrate data, or deploy components.
Detects suspicious activities related to the execution of qemu-system-x86_64, including scheduled task creation referencing 'TPMProfiler', execution under the SYSTEM account, and outbound network communication to known malicious IP addresses on specific ports (22, 32567, 22022).
This rule monitors for indicators of Impacket toolset usage across multiple data sources, including named pipe access (Event 5145), service creation (Event 7045), scheduled task creation (Event 4698), and process execution (Event 1). It flags suspicious activity associated with modules like secretsdump, wmiexec, psexec, and smbexec, aggregating findings by source host and user to evaluate the breadth of potential unauthorized activity.
This rule detects the creation of scheduled tasks using 'schtasks.exe' or PowerShell's 'Register-ScheduledTask' cmdlet. The detection focuses on command lines that include indicators of suspicious activity, such as encoded commands, hidden window styles, or placement in temporary or application data directories, specifically when the initiating process is not a signed Microsoft binary.
Detects persistence mechanisms associated with the MYRA RAT. This includes Linux/macOS crontab modification using specific schedules or shell profile writes initiated by node/npm processes, as well as Windows scheduled task creation or task manipulation via schtasks.exe initiated by node/npm processes.
Detects the creation of Windows Scheduled Tasks using either 'schtasks.exe' or 'powershell.exe' (via 'Register-ScheduledTask') with specific persistence flags, such as 'ONLOGON', 'ONSTART', 'SYSTEM' privileges, or 'HighestAvailable' execution levels. This behavior is commonly used by adversaries for persistence or privilege escalation.
This rule detects potential lateral movement activities by monitoring for the execution of 'psexec', 'wmiexec', or 'schtasks' commands within a short timeframe on the same computer. A count of 2 or more such command executions within an hour is flagged as suspicious, indicating potential adversary activity.
