Sub-technique of: T1003
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, also 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.
On Linux systems, Active Directory credentials can be accessed through caches maintained by software like System Security Services Daemon (SSSD) or Quest Authentication Services (formerly VAS). Cached credential hashes are typically located at /var/lib/sss/db/cache.[domain].ldb for SSSD or /var/opt/quest/vas/authcache/vas_auth.vdb for Quest. Adversaries can use utilities, such as tdbdump, on these database files to dump the cached hashes and use Password Cracking to obtain the plaintext password.
With SYSTEM or sudo access, the tools/utilities such as Mimikatz, Reg, and secretsdump.py for Windows or Linikatz for Linux can be used to extract the cached credentials.
Note: Cached credentials for Windows Vista are derived using PBKDF2.
Platforms: Windows, Linux
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
List credentials currently stored on the host via the built-in Windows utility cmdkey.exe Credentials listed with Cmdkey only pertain to the current user Passwords will not be displayed once they are stored
Supported Platforms: windows
cmdkey /list
If Atomic Red Team tests are not applicable, manually verify the technique by:
Identify Attack Surface: Determine if the target environment is susceptible to Cached Domain Credentials by examining the target platforms (Windows, Linux).
Assess Existing Defenses: Review whether mitigations for T1003.005 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
Consider adding users to the "Protected Users" Active Directory security group. This can help limit the caching of users' plaintext credentials.
Limit credential overlap across accounts and systems by training users and administrators not to use the same password for multiple accounts.
Ensure that local administrator accounts have complex, unique passwords across all systems on the network.
Consider limiting the number of cached credentials (HKLM\SOFTWARE\Microsoft\Windows NT\Current Version\Winlogon\cachedlogonscountvalue)
Do not put user or admin domain accounts in the local administrator groups across systems unless they are tightly controlled, as this is often equivalent to having a local administrator account with the same password on all systems. Follow best practices for design and administration of an enterprise network to limit privileged account use across administrative tiers.
