How to Know if Your Facebook Data Was Leaked to Cambridge Analytica

The numbers in the Cambridge Analytica Facebook scandal just keep climbing, from an original 55 million to a new estimate of nearly 87 million account holders who have had their data breached. This is because the quiz, "This Is Your Digital Life," collected data not only from Facebook users who completed it, but from all their Facebook friends as well. Facebook has barred the personality quiz from the platform and sent a message to all account holders who took the quiz, but if you'd like to make sure your data wasn't also breached, there's a way to find out. Let's check and see if our Facebook accounts have been compromised by Cambridge Analytica; it's easy to do right from your iPhone.

It's reasonable to assume that even if your account wasn't breached by this particular quiz, your data has been or is currently being mined by other Facebook apps and games. I highly recommend following this tip to see how many apps you've allowed to access your Facebook account, and deleting all but the ones you really need.
