Unconstrained Kerberos Delegation

T1558 · MITRE ATT&CK

On a compromised Windows computer or service host whose Active Directory principal has unconstrained Kerberos delegation, a user who authenticates to that service and is permitted to be delegated may leave a TGT in the host's LSASS ticket cache. An operator with sufficient authorized local access can inspect or export that ticket for credential access. The configuration does not itself force authentication, and the exported ticket does not reveal the user's password or NTLM hash.
