802.11 Man-in-the-Middle Attack Using Channel Switch Announcement

This paper presents a Wi-Fi Evil Twin, Man in the Middle attack (MiTM), which utilizes channel switch announcement (802.11h). The proposed technique examines and demonstrates through measurements the feasibility to perform a successful MiTM attack, when the target receives a lower received signal strength from the rogue access point (AP), compared to the received signal strength received by the legitimate AP. The above signal strength condition can allow the execution of a successful MiTM attack from relatively longer distances, since the rogue AP does not have to compete, signal strength wise, with the legitimate AP. Initial results suggest that the attack can be successfully performed. Furthermore, the attack is specific to a target and does not disrupt the operation of other targets, making the attack stealthy. � 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
