Now, a Palestinian hacker managed to break the privacy on Facebook and was able to post on non friends Facebook timeline. He was able to post links, statuses and photos. The hacker did a small test on a Sarah Gooden's timeline but later the hacker reported the vulnerability details to Mark Zuckerberg by posting on his timeline.

When he didn't got any proper response from Facebook team when he reported initially, Khalil was forced to post the vulnerability details to Mark Zuckerberg's timeline, he was contacted by Ola okelola, a Software Engineer at Facebook. The seriousness of the vulnerability was not much cared by Facebook.

After Facebook fixed the vulnerability, the team did not list the hacker's name on Facebook Whitehat thanks page due to a reason mentioned by the Facebook team. Usually, when someone reports a vulnerability to Facebook, they are paid with $500 but this time, they did not pay Khalil though the vulnerability was very much serious as it concerned about the privacy of a Facebook user.

When the hacker Khalil demanded for the credits, he was said that he violated the Facebook website Terms of Service and so he won't be getting paid.

The hacker Khalil still has to be paid by Facebook considering the seriousness of the vulnerability he reported to Facebook. His actions which made him to post on Mark Zuckerberg's timeline was that, he was not properly recognized initially when he reported the vulnerability details to Facebook team thrice.

The hacker who broke the privacy settings also made a video regarding how he posted links, status and photos to Facebook users who are not in their friend list.
