This detection rule focuses on identifying instances where the Windows Code Integrity service blocks the loading of images or drivers that do not conform to specified authenticode signing levels or violate established code integrity policies. Specifically, it targets events logged with Event ID 3077, which indicates that an image or driver was prevented from loading due to policy violations. The rule is particularly relevant for incidents involving privilege escalation attacks, as attackers may try to load malicious drivers or images to gain elevated privileges on a Windows system. This is an essential security measure aimed at maintaining the integrity of the system by enforcing strict code security standards. In the event of a blocked load, security teams should investigate the causes behind these events, which could indicate attempts at unauthorized changes to the system.
