Diablo 3 was yesterday the subject of a major hacker attack that has resulted in stolen accounts. The attack was the reason that many European servers were closed for up to four hours.
It grants Blizzard to Eurogamer.net, now that many gamers have complained about the lack of information on the official Battle.net forum.
At the forum, you can see several posts from people who have hacked their account with the result that all gold and all items are removed and transferred to others. Blizzard has backups of the characters from before the hacker attack and is currently working. to roll back the changes. The publisher can not guarantee that some accounts will not be lost forever.
I initially went the rumors on Battle.net forum that the long downtime was due to a SQL attack on Diablo database, but this is neither confirmed nor denied by Blizzard's side.
Reportedly, the hackers could get into accounts that would otherwise be protected by the Blizzard Mobile Authenticator.
