Over 25 Million Accounts Stolen After Mail.ru Forums Hacked

An anonymous reader writes: Over 25 million accounts associated with forums hosted by Russian internet giant Mail.ru have been stolen by hackers. Two hackers carried out attacks on three separate game-related forums in July and August. One forum alone accounted for almost half of the breached data -- a little under 13 million records; the other two forums making up over 12 million records. The databases were stolen in early August, according to breach notification site LeakedSource.com, which obtained a copy of the databases. The hackers' names aren't known, but used known SQL injection vulnerabilities found in older vBulletin forum software to get access to the databases. An analysis of the breached data showed that hackers took 12.8 million accounts from cfire.mail.ru; a total of 8.9 million records from parapa.mail.ru, and 3.2 million accounts from tanks.mail.ru. The hackers were able to obtain usernames, email addresses, scrambled passwords, and birthdays.
