One Stolen Active Directory File Can Expose Credentials for an Entire Windows Domain
Trellix warns that stealing a domain controller's NTDS.dit and SYSTEM hive can expose an entire Windows domain's credentials.
Trellix describes how theft of a domain controller's NTDS.dit database and SYSTEM registry hive can expose NTLM hashes, Kerberos keys, and password history for a Windows domain. Because the live database is locked, attackers commonly copy it from a Volume Shadow Copy and process it offline with tools such as Impacket or DSInternals. The write-up covers phishing or trojanized-installer access, credential theft from LSASS, pass-the-hash or pass-the-ticket movement, and SMB or HTTPS exfiltration. Recommended response includes isolation, privileged-account resets, and rotating KRBTGT twice to limit Golden Ticket reuse.

A single stolen Active Directory database can turn a limited Windows intrusion into a domain-wide credential compromise. Threat actors that obtain the NTDS. dIT file from a domain controller, along with its corresponding SYSTEM registry hive, can extract password hashes, Kerberos keys, and password-history data for domain identities offline.
