[ALERT!] Battle.net has been hacked, change your passwords
Hey g1s, it looks you should change that ol' password if you have a Battle.net account. The President of Blizzard, Mike Morhaime just released a "security update" alerting users that the North American servers have had their "cryptographic" passwords stolen along with some other information. NA servers "generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia".
"In the coming days, we'll [Blizzard] be prompting players on North American servers to change their secret questions and answers through an automated process." No financial information appears to be compromised, but it would probably be a good idea to change that password anyway. You can read the rest of the letter on Blizzard's site.
