CEH v13 describes relay attacks as credential forwarding techniques where attackers trick systems into authenticating to malicious servers, capturing hashes, and relaying them to privileged services. The described scenario aligns exactly with the PetitPotam attack, a known MS-EFSRPC abuse method that forces Windows domain controllers to perform NTLM authentication to attacker-controlled hosts. CEH discusses how relay attacks combined with Active Directory Certificate Services (AD CS) misconfigurations can allow attackers to request privileged certificates, effectively gaining domain administrator privileges without cracking hashes or accessing LSASS. CRIME (Option B) targets TLS compression and is unrelated. Browser token theft (Option C) applies to web sessions, not domain controllers. Session donation (Option D) is not part of Windows authentication hijacking. Thus, the scenario clearly represents a PetitPotam NTLM relay attack.
