While the game producer hasn’t let out any information about the number of unauthorized logins they have discovered Blizzard has noted that they are contacting users whose accounts have shown such activity. The recent violations have been observed in those accounts which are not using added security provided by the ‘authenticator’.
“We’re in the process of notifying any account holders who were not using an authenticator and whose account showed signs of unauthorized access (e.g., logging in from an unusual IP address). If you are among this group, you will receive an email describing how to reset your account”, reads the warning on World of Warcraft website.
As a precautionary measure Blizzard has blocked access to World of Warcraft auction house via the mobile app temporarily. If users, whose accounts have been hacked, contact customer support they will have their stolen in-game items and gold restored, the game producer has promised.
World of Warcraft has been in the news lately with entire cities found dead after an in-game hack in October last year followed by recent news that the online game has lost over 1.3 million users in 2013 alone.
