The only app that is able to countermeasure “Man In The Middle” attacks on Android platform – Wifi Protector. Protects your phone from tools like FaceNiff, Cain & Abel, ANTI, ettercap, DroidSheep, NetCut, and all others that try to hijack your session via ARP spoofing / ARP poisoning. WifiKill can’t take you offline with this app installed. The “Immunity” feature is the only one that requires root, all other features work without root access.
