Replay Attack

Sometimes known as a man in the middle attack, a replay attack is a type of security issue in which a third party intercepts data transmissions with the purpose of making use of that data in some manner. Typically, this type of attack involves copying and possibly altering the data in some manner before releasing it for delivery to the intended recipient. This method can be used to collect login credentials or other information that is intended to be proprietary, and use that information to gain unauthorized access to additional data.
