T1003.002 Security Account Manager Mappings

Adversaries may attempt to extract credential material from the Security Account Manager (SAM) database either through in-memory techniques or through the Windows Registry where the SAM database is stored. The SAM is a database file that contains local accounts for the host, typically those found with the <code>net user</code> command. Enumerating the SAM database requires SYSTEM level access.

A number of tools can be used to retrieve the SAM file through in-memory techniques:

Alternatively, the SAM can be extracted from the Registry with Reg:

  • <code>reg save HKLM\sam sam</code>
  • <code>reg save HKLM\system system</code>

Creddump7 can then be used to process the SAM database locally to retrieve hashes.(Citation: GitHub Creddump7)

Notes:

  • RID 500 account is the local, built-in administrator.
  • RID 501 is the guest account.
  • User accounts start with a RID of 1,000+.
