relay attack

A relay attack (also known as the two-thief attack) in computer security is a type of hacking technique related to man-in-the-middle and replay attacks. In a classic man-in-the-middle attack, an attacker intercepts and manipulates communications between two parties initiated by one of the parties. In a classic relay attack, communication with both parties is initiated by the attacker who then merely relays messages between the two parties without manipulating them or even necessarily reading them.
