NtdsAudit

NtdsAudit is a credential-dumping tool used to extract domain user password hashes from Microsoft Active Directory data, specifically by operating on copies of the NTDS.dit database together with the SYSTEM registry hive. In the provided reporting, Chimera is explicitly documented using NtdsAudit via the command msadcs.exe "NTDS.dit" -s "SYSTEM" -p RecordedTV_pdmp.txt --users-csv RecordedTV_users.csv to dump password hashes of domain users. The same reporting states that Chimera gathered the SYSTEM registry and NTDS.dit files from target systems and used ntdsutil to copy the Active Directory database before using NtdsAudit. The tool is therefore associated with credential access against Windows domain controllers and Active Directory environments. High-confidence indicators from the content include the tool name NtdsAudit, execution via msadcs.exe, and the referenced output artifacts RecordedTV_pdmp.txt and RecordedTV_users.csv. The only threat actor directly associated with this tool in the provided content is Chimera.
