Group Policy Abuse for Privilege Addition
Detects modifications to Group Policy Object (GPO) attributes, specifically 'gPCMachineExtensionNames', that are indicative of adding privileges to user accounts or adding users as local administrators. This is identified by the presence of specific GUIDs ('827D319E-6EAC-11D2-A4EA-00C04F79F83A' or '803E14A0-B4FB-11D0-A0D0-00A0C90F574B') within the 'AttributeValue' field of EventID 5136. These GUIDs are associated with Group Policy extensions that can be abused for privilege escalation.
