A security incident has launched a full-on investigation over at Wargaming. They say that some of their World of Tanks players' personal information may have been compromised and are now asking that all players change their passwords.
Wargaming is sure that no financial information was accessed, but they believe that some password hashes and email addresses have got out. They've launched a global campaign to increase account security, and are giving those that follow through with a reset 300 Gold.
If you are one of the tens of millions that play World of Tanks, please go change your passwords now.
