What it detects

This rule flags registry writes that set EnableLUA to DWORD 0 under the Policies\System path, indicating an attempt to disable User Account Control. Disabling UAC can reduce protections around elevation prompts and facilitate privilege escalation. The detection relies on Windows registry set telemetry capturing the TargetObject path and the written DWORD value.
