A security flaw is exposing the passwords of millions of Facebook users. Researchers at Krebs say the passwords of as many 600 million users were stored in plain text accessible to employees of Facebook. For its part, the social media giant said it has fixed a glitch that caused passwords to be stored on its internal network. Facebook added it had not uncovered any signs of misuse. The passwords that were exposed could date back to 2012. But to be on the safe side, go ahead and change your passwords anyway.
