Description

The following analytic identifies the execution of `auditpol.exe` with the "/resourceSACL" flag, and either the "/clear" or "/remove" command-line arguments used to remove or clear the global object access audit policy. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity can be significant as it indicates potential defense evasion by adversaries or Red Teams, aiming to limit data that can be leveraged for detections and audits. If confirmed malicious, this behavior could allow attackers to bypass defenses, and plan further attacks, potentially leading to full machine compromise or lateral movement.

  • False positives should be rare to non existent. Any activity detected by this analytic should be investigated and approved or denied.
