Facebook has fixed a serious security bug that could have been exploited by hackers to delete any video shared by anyone on their wall. The bug was discovered by the security researcher Dan Melamed. Facebook rewarded the bug hunter $10,000 under its bug bounty program. A similar issue was discovered in June 2016 by the Indian security researcher Pranav Hivarekar who demonstrated that was able to delete videos by exploiting a security issue that exists in the recently introduced video comment feature. The expert also discovered that was possible to disable commenting on any video.”]
