Millions Affected By Facebook Breach
A cybersecurity expert is calling the latest Facebook security breach "among the worst kinds out there".
On Friday, Facebook announced it had discovered a security issue affecting almost 50 million accounts.
It said hackers exploited a vulnerability affecting its "View As" feature, which lets you see what your profile looks like to someone else.
David Shipley, CEO of Beauceron Security in Fredericton, said the attackers stole "access tokens" — digital keys which keep people logged into Facebook.
