I would take this post as more of a warning for all who have a facebook account to make sure they lock it down before you have anyone on your Wi-Fi hacking into it and exploiting it. The FaceNiff app will actually creep into secure networks as well running WPA, WEP, and WPA2, so its really best to lock your facebook down too by setting your account access to use ‘https’. The developer Bartosz Ponurkiewicz lets us know that this not only works with facebook, but also Twitter, YouTube and Nasza-Klasa (a Polish Facebook clone). He also states that more site login support will be on the way.
In the video below, you’ll see how easy it is for someone to use this app and gain access to your facebook page with nothing but an Android device, making this a good secret weapon for your prankster friends, or even a revengeful tool for your enemies. Check it out. Also, instructions to lock your facebook page can be found here.
