The detection rule focuses on monitoring and identifying instances where the Windows Code Integrity service blocks the loading of an image due to a revoked certificate. This can occur when a previously trusted executable or image has had its certificate revoked for security reasons, such as being flagged as potentially malicious. It is especially critical for safeguarding against privilege escalation attacks, as the loading of compromised or unauthorized images can allow attackers to gain elevated permissions on a system. This rule utilizes event ID 3036, which is generated when Code Integrity blocks the loading of an image.
