Facebook ups login security, outs hacker with 1.5M accounts
Facebook says it has discovered the identity of "Kirllos," the hacker who claimed to be selling 1.5 million Facebook logins on the black market last month. It turns out that Kirlios didn't quite have as many accounts as he originally claimed, though he did manage to sell a number of credentials to third parties. Facebook has also updated its login system to make it more secure for users who want to make sure they maintain control of their accounts.
