Cambridge Analytica might have accessed private Facebook messages
Facebook just began notifying people if their information was accessed by Cambridge Analytica today. Soon after, the social media company created a Help Center page that you can check to see if you were one of the affected members who logged into quiz app This Is Your Digital Life. Apparently, doing so not only shared your News Feed, timeline and posts, but also your private messages.
Facebook confirmed to Wired that the app used a read_mailbox permission, which, unlike other sensitive permissions that Facebook phased out a in April of 2015, didn’t fully deprecate until October of that same year.
Wired reports that while users would have needed to give their permission for the app (and hence Cambridge Analytica) to access their message inboxes, the request would have likely been hidden in with a bunch of other permission requests, which users may have missed when “agreeing” to share their data. Facebook says that a total of 1,500 people gave This Is Your Digital Life permission, though the total of actual users affected is unknown. The problem goes beyond those that granted permission to share; if you in some way messaged with any of those users, you might be also impacted.
