An attack where a user gets between the sender and receiver of information and sniffs any information being sent. In some cases, users may be sending unencrypted data, which means the man-in-the-middle (MITM) can obtain any unencrypted information. In other cases, a user may be able to obtain information from the attack, but have to unencrypt the information before it can be read. In the below picture is an example of how a man-in-the-middle attack works. The attacker intercepts some or all traffic coming from the computer, collects the data, and then forwards it to the destination the user was originally intending to visit.
