Pitt study shows how Facebook’s mutual-friends feature
creates security risks, privacy concerns
The mutual-friends feature on social networks such as
Facebook, which displays users’ shared friendships, might not be so “friendly.”
Often revered for bringing people together, the
mutual-friends feature on Facebook actually creates myriad security risks and
privacy concerns according to a University of Pittsburgh study published in
Computers & Security. The study demonstrates that even though users can
tailor their privacy settings, hackers can still find private information
through mutual-friends features.
