New NTLM Relay Attack Lets Attackers Take Control Over Windows Domain - The Hacker News

A new kind of Windows NTLM relay attack dubbed DFSCoerce has been uncovered that leverages the Distributed File System (DFS): Namespace Management Protocol (MS-DFSNM) to seize control of a domain.

"By relaying an NTLM authentication request from a domain controller to the Certificate Authority Web Enrollment or the Certificate Enrollment Web Service on an AD CS system, an attacker can obtain a certificate that can be used to obtain a Ticket Granting Ticket (TGT) from the domain controller," the CERT Coordination Center (CERT/CC) noted, detailing the attack chain.
