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.
Facebook has not published Kirllos’ identity, but says that he is based in
Russia and the company has alerted local law enforcement to his activities. "We
have determined Kirllos’ identity through IP addresses, online accounts, and
other information and believe that he’s very likely a low-level actor," Facebook
Spokesman Simon Axten told ComputerWorld.
