Detects the creation of a scheduled task named 'OneDriveUpdateScheduler' and the subsequent execution of 'update1.ps1' or 'update2.ps1' by 'explorer.exe'. This behavior is associated with the Konni/VelvetCake malware families, which use this technique to maintain persistence and C2 connectivity.

Detects the creation of a scheduled task via schtasks.exe initiated by wscript.exe or cscript.exe where the task configuration or execution occurs within common user-writable directories (e.g., AppData, Temp, Downloads). The rule specifically flags behavior involving multiple task invocations in a short time frame, which is indicative of persistence mechanisms used by scripts.

Detects creation of the 'keyroll' scheduled task used to relaunch the Sauron Loader DLL side-loading chain. Requires the schtasks.exe command line to both reference the 'keyroll' task name AND explicitly reference the ProgramData\keyroll path or rnpkeys.exe (ruling out unrelated tasks that happen to be named 'keyroll', e.g. legitimate key-rotation automation), and requires an INNER join corroborating an actual rnpkeys.exe relaunch from that path within 24h — a lone task-creation event with no follow-on relaunch no longer alerts.

Detects a suspicious sequence of events where a process creates a scheduled task named 'WindowsUpdate' followed by execution of 'netsh' commands to dump wireless profiles or clear keys within a 15-minute window. This behavioral pattern is often associated with credential-stealing malware attempting to establish persistence and harvest sensitive information.

Detects the creation of scheduled tasks using schtasks.exe or Event ID 4698, specifically filtering for tasks that execute PowerShell, WScript, or JavaScript files. This behavior is indicative of potential persistence mechanisms, such as those observed in the LausivLoader.

105
This rule detects the creation or registration of scheduled tasks using common scripting engines (PowerShell, WScript, CScript) or specific task name patterns (MicrosoftEdgeUpdateTaskCore, PhotoStudio.js) often associated with malicious persistence or execution. It monitors command lines for flags such as /create, /sc onlogon, or /ru system that suggest non-standard or unauthorized task creation patterns.

Detects the execution of 'ReportDump.exe' from within the 'C:\ProgramData' directory when initiated by system processes associated with scheduled tasks (svchost.exe, taskeng.exe, schtasks.exe) containing 'Schedule' in the command line. This behavior is indicative of potential persistence mechanisms or malicious file execution using legitimate Windows scheduling utilities.

301
This rule monitors for coordinated persistence efforts by detecting the occurrence of at least two out of three specific persistence techniques (registry run key modification, scheduled task creation, or WMI-based script execution) on the same device within a 30-minute window. It explicitly filters out activities from signed binaries or those occurring in standard system/application directories, focusing on potentially malicious artifacts originating from user-writable locations.

Detects suspicious PowerShell activity involving compression commands (e.g., Expand-Archive) within APPDATA, correlated with the execution of hypersnap.exe with hidden window arguments, and the creation of persistence via scheduled tasks. This pattern is indicative of automated staging or malicious tool execution and persistence setup.

Detects suspicious behavior where an identical executable (same path and SHA256) is launched twice within a short window (60 minutes) following a system reboot, utilizing two distinct persistence methods: one triggered via the Task Scheduler (under svchost.exe -k netsvcs) and one via a user logon autostart mechanism (spawned by explorer.exe).

Detects the creation of scheduled tasks initiated by the WinGet DSC configuration processes, specifically ConfigurationRemotingServer.exe or WindowsPackageManagerServer.exe. This activity is indicative of the abuse of the 'ScheduledTask' resource within a WinGet configuration file to establish persistence via a logon-triggered task.

Detects the creation of a suspicious scheduled task named 'MicrosoftMusicLibrariesPackageTaskMachine' and the execution of 'codeflush.exe' involving 'settingenv.cat'. These activities are associated with persistence and defense evasion techniques often used by malicious actors.

Detects the creation or execution of a scheduled task named 'MicrosoftMusicLibrariesPackageTaskMachine' and the invocation of specific associated file names 'codeflush.exe' or 'settingenv.cat', which are indicators of persistence used by the threat actor APT37.

Detects the execution of the Chisel C2 tool by matching its unique command-line grammar, specifically the 'client' subcommand combined with reverse remote ('R:') configurations. This detection strategy is resilient against binary renaming and infrastructure rotation by focusing on the tool's required argument structure rather than static IOCs like filenames or C2 addresses. It is specifically useful for identifying unauthorized remote tunnels used for persistence and data exfiltration.

Detects the creation of scheduled tasks using schtasks.exe or PowerShell that reference specific task names associated with potentially suspicious activity or persistence (e.g., PlutonAgentScheduler, EnterpriseMgmtServicesScheduler). The rule specifically looks for tasks being placed or modified within 'microsoft' or 'pluton' directories or paths, which may indicate an attempt to masquerade as legitimate system services.

Detects MayaBot's scheduled-task persistence chain by correlating two signals on the same device within a 60-minute window: (1) schtasks.exe creating a daily task referencing a hidden batch script (update.bat/backup.bat/firewall-update.bat) under AppData\Local, spawned from wscript.exe/cscript.exe/cmd.exe, and (2) cmd.exe launching a hidden-window PowerShell process referencing the same batch scripts under AppData\Local. Requiring both signals together, anchored to the AppData\Local path, sharply reduces false positives compared to alerting on either behavior alone.

Detects instances where PowerShell scripts are executed via the Windows Task Scheduler from within potential staging directories (ProgramData with randomized folder names). The rule identifies execution that uses common PowerShell obfuscation flags (e.g., -EncodedCommand) and requires secondary hardening bypass flags (e.g., -WindowStyle hidden), followed by correlated network activity to a specific suspicious C2 domain.

Detects the execution of MicrosoftIME.exe or the creation of scheduled tasks referencing it from non-standard directories such as User, Temp, or AppData folders. This behavior is indicative of masquerading or persistence mechanisms where a malicious process mimics the legitimate Microsoft Input Method Editor (IME) binary.
