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)

Microsoft Defender security alerts explain the suspicious activities detected by Defender for Identity sensors on your network, and the actors and computers involved in each threat. Alert evidence lists contain direct links to the involved users and computers, to help make your investigations easy and direct.
Defender security alerts are divided into the following categories or phases, like the phases seen in a typical cyber-attack kill chain. Learn more about each phase, the alerts designed to detect each attack, and how to use the alerts to help protect your network using the following links:
Reconnaissance and discovery alerts
Persistence and privilege escalation alerts
Credential access alerts
Lateral movement alerts

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.
