Blizzard Network Breached; Change Your Battle.Net Passwords
"Some data was illegally accessed, including a list of email addresses for global Battle.net users, outside of China. For players on North American servers (which generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia) the answer to the personal security question, and information relating to Mobile and Dial-In Authenticators were also accessed. Based on what we currently know, this information alone is NOT enough for anyone to gain access to Battle.net accounts."The part where it says, "answer to the personal security question" were accessed should be EXTREMELY ALARMING. This combined with an email addresses is usually enough to get your password reset on lots of sites. I believe this will reset your password on Google (assuming you're not using 2 factor).
