T1550.002 / ATT&CK
Use Alternate Authentication Material: Pass the Hash
15 rules across 3 sources.
From MITRE ATT&CK 19.2
Adversaries may “pass the hash” using stolen password hashes to move laterally within an environment, bypassing normal system access controls. Pass the hash (PtH) is a method of authenticating as a user without having access to the user's cleartext password. This method bypasses standard authentication steps that require a cleartext password, moving directly into the portion of the authentication that uses the password hash.
When performing PtH, valid password hashes for the account being used are captured using a Credential Access technique. Captured hashes are used with PtH to authenticate as that user. Once authenticated, PtH may be used to perform actions on local or remote systems.
Adversaries may also use stolen password hashes to "overpass the hash." Similar to PtH, this involves using a password hash to authenticate as a user but also uses the password hash to create a valid Kerberos ticket. This ticket can then be used to perform Pass the Ticket attacks.

Detection Strategy for T1550.002 - Pass the Hash (Windows)
Windows Analytic 1144
Detects anomalous NTLM LogonType 3 authentications that occur without accompanying domain logon events, especially from lateral systems or involving built-in administrative tools. Monitors for mismatches between source user context and system being accessed. Correlates LogonSession creation, NTLM authentications, and process/service initiation to identify suspicious use of stolen password hashes for remote access or service logon without password entry. Detects overpass-the-hash by combining Kerberos ticket issuance with NTLM-based lateral movement.
