What it detects

This rule detects command-line references to the NTDS.dit Active Directory database being copied or dumped, a credential-theft step seen in CitrixBleed post-exploitation. Attackers extract NTDS.dit to harvest domain credential hashes for offline cracking and further compromise. Because access to this file outside of backup or DC maintenance is rare, it is a strong indicator of domain credential theft.
