What it detects
This rule identifies attempts to back up the DPAPI Domain Master Key using Windows Security auditing. Attackers may use DPAPI key material access to enable decryption of protected credentials or sensitive data across a domain. It relies on Windows Security Event ID 4692 telemetry emitted by the source system generating the event rather than the Domain Controller.
