LinkedIn is moving quickly to deal with a possible data release from a 2012 security breach, which could include 117M passwords. A hacker is reportedly looking to sell the user data on Dark Web marketplace TheRealDeal for 5 bitcoins (about $2,200). "We've begun to invalidate passwords for all accounts created prior to the 2012 breach that haven't updated their password," said May Chow of LinkedIn's corporate communication.
