Remote Task Creation via ATSVC Named Pipe

SigmaHQ Detections@sigmaHQ

•updated Oct 23, 2025•0•35

This rule detects the remote creation of scheduled tasks by monitoring access to the 'ATSVC' named pipe within the IPC$ share. Specifically, it looks for Event ID 5145, indicating a detailed file share access, where the ShareName is '\\*\IPC$', the RelativeTargetName is 'atsvc', and the AccessList contains 'WriteData'. This activity is characteristic of tools like 'at.exe' or direct API calls used to schedule tasks remotely.
