Faceniff - Pwning Facebook was never so easy! This is by far one of my favorite apps! Faceniff is a Session Hijacker like Firesheep or hamster/ferret but BETTER. No more need to use cain and able and firesheep to hijack. Also who would suspect a cell phone as a hacking tool? Devlish Faceniff will sniff the network and display active sessions and Hijack them! It can hijack the following - 
FaceBook
Twitter
Youtube
Amazon
VKontakte
Tumblr
MySpace
Tuenti
MeinVZ/StudiVZ
blogger
Nasza-Klasa
