What it detects

This rule detects creation of an ntds.dit Active Directory database copy under a C drive audit Active Directory path. During the Anubis ransomware intrusion the operators exfiltrated domain credentials by copying the NTDS database into an audit directory and archiving it, an activity that does not occur during normal operations.
