Thought Your Facebook Friends List was Private? Think Again!
PARIS, Nov. 22, 2013 /PRNewswire/ -- Researchers from the Quotium Seeker Research Center identified a security flaw in Facebook privacy controls. The vulnerability allows attackers to see the friends list of any user on Facebook. This attack is carried out by abusing the 'People You May Know' mechanism on Facebook, which is the mechanism by which Facebook suggests new friends to users.
With attacks being on the rise, Facebook is often targeted by hackers for the information it possesses. Users rely on Facebook to maintain their privacy to the best of Facebook's ability.
FB responded that: "If you don't have friends on Facebook and send a friend request to someone who's chosen to hide their complete friend list from their timeline, you may see some friend suggestions that are also friends of theirs. But you have no way of knowing if the suggestions you see represent someone's complete friend list." However, research of this issue has shown that most of the friends list, often hundreds of friends, is available to the attacker. In any case, even a partial friends list is a violation of user-chosen privacy controls.
Since this vulnerability renders the privacy control to hide friend's lists from other users irrelevant, we hope Facebook will change its mind and this flaw will be addressed.
