What it detects

This rule detects use of ntdsutil to create an install from media snapshot which extracts the Active Directory database and this technique was used during the NetSupport intrusion to steal the domain credential store and this matters because IFM creation dumps every domain hash in one operation and is almost never run by legitimate operators outside of controlled domain controller provisioning.
