A hacker called Bartosz Ponurkiewicz has released a simple Android app called Faceniff (Facebook + Sniff), which allows you to hijack the Facebook profile of anyone on same wireless network as you. Think Firesheep, but running on something you can slip in your pocket and carry anywhere. Oh, and it’s “for educational use only” 😉 Understand?
The interesting thing about Faceniff is that it works with WPA2-PSK encrypted networks (as well as the lower grade WAP protocol). So it doesn’t matter how strong your wireless encryption is, it’s still susceptible to inside attacks. All you need is a rooted Android phone with Faceniff installed.
