The Evil Twin attack is a wireless attack that involves an attacker turning their wireless card into an "evil twin" access point with the same name and MAC address. The attacker attempts to get the target to connect to the Evil Twin router, instead of the Good Twin router. This enables a man-in-the-middle attack.
