Description
This module creates an SMB server and relays the Kerberos AP-REQ passed to it (for example from a coerced host, CVE-2026-20929) to an AD CS Web Enrollment HTTP endpoint to gain an authenticated connection. Once that connection is established, the module makes an authenticated request for a certificate based on a given template.
Unlike NTLM, a Kerberos AP-REQ is a complete, self-contained credential bound to the SPN the victim was coerced into requesting, so there is no challenge/response and the relay is a single request. The captured AP-REQ can only be relayed to the service matching that SPN.
