WebMar 16, 2024 · A replay attack is an attack in which the adversary records a communication session and replays the entire session, or some portion of the session, at a later point in time. The replayed message(s) may be sent to the same verifier as the one that participated in the original session, or to a different verifier. The goal of the replay attack may be … WebDec 2, 2024 · A session replay attack is a passive type of man-in-the-middle attack that fools the network servers into thinking they are communicating with valid clients. When this happens, the server or receiver gets the message twice — once from the true sender and once from the attacker. This is the reason for the name “replay attack.”.

A replay attack (also known as a repeat attack or playback attack) is a form of network attack in which valid data transmission is maliciously or fraudulently repeated or delayed. This is carried out either by the originator or by an adversary who intercepts the data and re-transmits it, possibly as part of a spoofing attack by IP packet substitution.
