The hacker Dr.FarFar claimed that he changed the Timeline Cover Photo of Mark Zuckerberg’s Facebook account.

Hacker Dr.FarFar explained that he used the “Report abuse” option on Zuckerberg’s Cover image, and choosed, “I don’t like this photo of me” and then “I used Fiddler2 Debugger Program to edit the request”.

With all this demonstration, it’s still not sure to say that the Facebook account was hacked, an error could occur.
