Forum Thread: How to Hack Fb Account

Here's an article on what I believe you're looking for.

You should try pishing: Copying the Facebook login, then changing a bit of the code sothat the entered credentials are saved in a text-file and then hosting it somewhere. You can also use the Social Engineering Toolkit that comes with Metasploit, but can be downloaded for any Linux (dont know about Windows, but could be).

--> Its illegal, dont do it.
