What it detects
This rule detects ntdsutil being used to create an installation from media (IFM) copy of the Active Directory database, a credential-access technique observed in BlackSuit ransomware intrusions. Dumping NTDS.dit gives operators every domain hash for offline cracking and full domain compromise, making this a critical detection.
Reporting behind it
Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
