Kerberos Relay

T1557 · MITRE ATT&CK

Kerberos relay forwards a victim's service-ticket AP-REQ to a service that can accept that service principal, enabling access without obtaining the victim's plaintext password. This entry's worked flow is HTTP relay to AD CS Web Enrollment using multicast name-resolution poisoning or an optional WebDAV coercion. Kerberos-over-DNS and Kerberos-over-SMB are separate variants with different prerequisites; a successful AD CS enrollment can yield a certificate that may then be used with PKINIT to request a TGT.
