SMB Relay Attack

In this recorded demonstration, we break down how an SMB Relay Attack works in an Active Directory environment. Watch step by step as we intercept NTLM authentication traffic and relay it to a target system that lacks SMB signing. This penetration testing technique allows attackers to bypass password cracking entirely and gain unauthorized access or a remote shell. Discover how these attacks are executed using tools such as Responder and ntlmrelayx, and, most importantly, learn the critical defensive configurations (such as enforcing SMB signing) needed to secure your network.
