What it detects

This rule detects scheduled task hosts launching rundll32 powershell or cmd with a payload located under AppData Roaming or AppData Local Temp which is how GootLoader maintains persistence and execution. Interpreters spawned by the task scheduler from user writable directories are a strong indicator of GootLoader activity.
