What man-in-the-middle attack is a danger for 802.11 WLANs?
Answer: The most dangerous man-in-the-middle attack for 802.11 WLANs is the evil twin access point. An evil twin access point is simply a PC that has software that allows it to masquerade as a legitimate access point. The evil twin will pass traffic to legitimate access points transparently, retaining copies of important data sent from the host and a legitimate access point. Evil twin access points can intercept messages during and after security setup, allowing the evil twin to have the necessary keys to decrypt all traffic during a specific session.
