What “unauthorized…

Monitoring Group Policy for backdoors

October 31, 2025
Monitoring Group Policy for Backdoors (GPO Tampering Detection & Response) Group Policy is one of the most powerful configuration channels in Active Directory—and that’s exactly why attackers love it. If a threat actor gains the ability to edit a Group Policy Object (GPO) (or its SYSVOL content), they can push “legitimate” settings that…
