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.(Citation: Stealthbits Overpass-the-Hash)

| PR.PS-02.01 | Patch identification and application | Mitigates | T1550.002 | Pass the Hash |
Comments
This diagnostic statement is related to the implementation of a patch management program. Applying patches and upgrades for products and systems provided by vendors mitigates the risk of adversaries exploiting known vulnerabilities. An example of this for Pass the Hash is to update software by applying patch KB2871997 to Windows 7 and higher systems, limiting the default access of accounts in the local administrator group.

Comments
This control's "Reduce lateral movement path risk to sensitive entities" recommendation can lead to protecting sensitive accounts against Pass-the-Hash and Pass-the-Ticket attacks by recommending running the Lateral-Movement-Paths report to understand and identify exactly how attackers can move laterally through the monitored network to gain access to privileged identities. Because this is a recommendation, its score has been capped as Partial.

Comments
Defender for Identity LMPs are visual guides that help you quickly understand and identify exactly how attackers can move laterally inside your network. The purpose of lateral movements within the cyber-attack kill chain are for attackers to gain and compromise your sensitive accounts using non-sensitive accounts. Compromising your sensitive accounts gets them another step closer to their ultimate goal, domain dominance. To stop these attacks from being successful, Defender for Identity LMPs give you easy to interpret, direct visual guidance on your most vulnerable, sensitive accounts.
