Yahoo Says 500 Million User Accounts Hacked by 'State-Sponsored Actor'

Yahoo announced that the account information of least 500 million users was stolen by hackers two years ago. In a statement, Yahoo said user information — including names, email addresses, telephone numbers, birth dates, passwords, and in some cases security questions — was compromised in 2014 by what it believed was a “state-sponsored actor.” It did not name the country involved.
