Today you have Faceniff that is used to hijack popular social networking websites like Twitter and Facebook. Your Facebook profile might be at risk just like the Firesheep (for firefox hacking). However, this should work on private networks as well as open, WEP, WPA-PSK, WPA2-PSK and WPA-3. When the WiFi is not using the EAP only, then it is possible to hijack sessions. It allows you to intercept and smell profiles of web sessions via WiFi with which your phone is connected. FaceNiff is an android app used for highjacking sessions.
