A hacker has stolen the login information for 200 million Yahoo accounts and is now selling them on the black market on TheRealDeal. The price is he asking is 3 bitcoins, or €1,618. The hacker, called peace_of_mind (ironically) stated that he stole the Yahoo credentials from LinkedIn and Tumblr users, as well as MySpace. Back in 2012, Yahoo reported a breach, but of only 450,000 accounts. A hacking group called D33ds Company had claimed responsibility, however Yahoo said that most of the stolen passwords were invalid.

Peace_of_mind has posted a sample of the stolen Yahoo database, which includes user e-mail addresses, along with passwords that have been hashed using the MD5 algorithm. Those passwords could easily be cracked using a MD5 decrypter available online. The database also contains backup e-mail addresses, as well as the users’ birth dates. DG News Service tried several e-mail addresses from the stolen records and noticed that Yahoo’s login page recognised them and then asked for a password. However, other e-mails addresses were no longer valid.

Yahoo has not yet confirmed the breach, but users are advised to change their passwords.
