Question

During a Windows engagement, you established persistence using a scheduled task, a Run registry key, and a WMI event subscription. The engagement is ending and the client requires the environment restored to its pre-test state. Which approach best ensures complete cleanup of your persistence mechanisms?

Accepted Answer

Consult the activity log you maintained throughout testing to identify each artifact created, then systematically remove the scheduled task, the registry Run key value, and the WMI event subscription, verifying each removal

Answer

Delete only the scheduled task, since it is the most easily detected mechanism, and leave the others for the client's blue team to find as a detection exercise

Answer

Run a commercial anti-malware scan on the host and assume it will remove all traces of your implants automatically

Answer

Reboot the host to clear all in-memory implants and consider the persistence removed
