Cached Domain Credentials

Adversaries may attempt to access cached domain credentials used to allow authentication to occur in the event a domain controller is unavailable.

On Windows Vista and newer, the hash format is DCC2 (Domain Cached Credentials version 2)hash, known as MS-Cache v2 hash. The number of default cached credentials varies and can be altered per system. This hash does not allow pass-the-hash style attacks, and instead requires Password Cracking to recover the plaintext password.

With SYSTEM access, tools/utilities such as Mimikatz, Reg, and can be used to extract the cached credentials.

Note: Cached credentials for Windows Vista are derived using PBKDF2.


We can achieve this as well with mimkatz using the lsadump::cache module and retrieve the hashes.
