A replay attack (also known as playback attack) is a form of network attack in which valid data transmission is maliciously or fraudulently repeated or delayed.[1] 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. This is one of the lower-tier versions of a man-in-the-middle attack. Replay attacks are usually passive in nature.
