Which attack technique is likely used in a simulated relay attack?

In a simulated relay attack, the primary technique involved is closely aligned with how data is intercepted and manipulated between parties in a communication. The correct answer is centered on the methodology where authentication tokens or credentials are compromised and reused without direct access to the user’s password.

A simulated relay attack typically mimics a real relay attack, where the attacker intercepts the authentication process between a client and a server. In this scenario, a Pass-the-Hash attack is particularly relevant. This technique specifically allows an attacker to use a stolen hash of a user's password to authenticate themselves to a server without needing the plain-text password.

In the context of a relay attack, the attacker presents valid credentials or hashes to the target system, tricking it into thinking the connection is legitimate. This operates on the premise that as long as the hash is valid and connected to a trusted session, the attacker can gain unauthorized access.

In contrast, options such as Session fixation or SQL Injection focus on other vectors of attack that do not share the same mechanics as a relay scenario. Session fixation relates to setting a user's session ID, while SQL Injection involves manipulating a web application's database queries, neither of which mirrors the operational details of a relay attack as closely as a Pass-the-Hash attack does
