has just posted an "important security update" to its official site. The studio responsible for World of Warcraft
, Diablo III
, and StarCraft
revealed that its security team "found an unauthorized and illegal access" into Blizzard's internal network.
While Blizzard president Mike Morhaime explains that no financial data (like credit card details, real names, and billing addresses) were compromised as a result of the security breach, he does admit that emails, answers to security questions, and encrypted Battle.net passwords of North American players (and others outside of China) were accessed.
"Based on what we currently know, this information alone is NOT enough for anyone to gain access to Battle.net accounts," wrote Morhaime, but the company is still investigating the breach and recommends that all players change their passwords "as a precaution."
