What it detects

This rule detects schtasks.exe creating a scheduled task whose action runs a command shell, PowerShell or another script interpreter or a payload from a user-writable path. Scheduled Task abuse is a top persistence and execution technique in the Red Canary Threat Detection Report, letting adversaries survive reboots and run code on a trigger. Detecting task creation that wraps an interpreter or suspicious path surfaces the persistence attempt as it is registered.
