Attackers commonly attempt to exfiltrate this file to perform offline credential recovery. This activity often involves native binaries like ntdsutil, which can be misused to create an Install from Media (IFM) set, or simple file system operations to copy the database file. Additionally, offensive security tools such as NTDSDumpEx or PowerShell-based scripts are frequently deployed in compromised environments. Defenders must monitor for unauthorized execution of these tools or suspicious process behavior that interacts with the NTDS.DIT file path.
