This analytic identifies an on demand run of a Windows Schedule Task through shell or command-line. This technique has been used by adversaries that force to run their created Schedule Task as their persistence mechanism or for lateral movement as part of their malicious attack to the compromised machine.

How To Implement

To successfully implement this search, you need to be ingesting logs with the process name, parent process, and command-line executions from your endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the Sysmon TA. Tune and filter known instances where renamed schtasks.exe may be used.

Required field

  • _time
  • Processes.process
  • Processes.process_id
  • Processes.process_name
  • Processes.parent_process_name
  • Processes.dest
  • Processes.user

Kill Chain Phase

  • Exploitation

Known False Positives

Administrators may use to debug Schedule Task entries. Filter as needed.
