Adversaries may “pass the ticket” using stolen Kerberos tickets to move laterally within an environment, bypassing normal system access controls. Pass the ticket (PtT) is a method of authenticating to a system using Kerberos tickets without having access to an account's password. Kerberos authentication can be used as the first step to lateral movement to a remote system.

how MITRE says to see it
Detection Strategy for T1550.003 - Pass the Ticket (Windows)
- Detects unauthorized Kerberos ticket injection by correlating service ticket (TGS - 4769) requests with absent corresponding account logons (4624) and prior Ticket Granting Ticket (TGT - 4768) activity.
what reduces it
- M1027 Password Policies. Ensure that local administrator accounts have complex, unique passwords.
- M1018 User Account Management. Do not allow a user to be a local administrator for multiple systems.
- M1026 Privileged Account Management. Limit domain admin account permissions to domain controllers and limited servers. Delegate other admin functions to separate accounts.
- M1015 Active Directory Configuration. To contain the impact of a previously generated golden ticket, reset the built-in KRBTGT account password twice, which will invalidate any existing golden tickets that have been created with the KRBTGT hash and other Kerberos tickets derived from it. For each domain, change the KRBTGT account password once, force replication, and then change the password a second time.
