Which method provides lateral movement within a network during a pass-the-ticket attack?

• A. Intercepting network traffic
• B. Using stolen credentials
• C. Compromising the TGT
• D. Exploiting software vulnerabilities

Answer: (C)

In a pass-the-ticket attack scenario, the technique that enables lateral movement within a network is the compromising of the Ticket Granting Ticket (TGT). A TGT is part of the Kerberos authentication protocol, which is commonly used in enterprise environments. When an attacker successfully obtains the TGT, they can impersonate a legitimate user across the network without needing to re-enter a password. This ability to leverage the ticket allows the attacker to access various network resources and services as if they were the legitimate user. The compromise of the TGT effectively negates the need for the attacker to gather further credentials or exploit additional vulnerabilities for access, as they can use the stolen ticket to authenticate directly to other services within the network. This method highlights the importance of securing Kerberos tickets and monitoring for unusual access patterns that may indicate lateral movement due to an attack. Other methods, such as intercepting network traffic, using stolen credentials, or exploiting software vulnerabilities, do not directly relate to lateral movement specifically facilitated by the use of Kerberos tickets. Each of these methods can play a role in broader attack strategies, but compromising the TGT is uniquely suited to facilitating lateral movement through existing authentication mechanisms.
