Harmonix' network of Rock Band and Dance Central websites went down over the weekend to investigate an intrusion into their network. No evidence of any compromised user account details have yet been found, but at the time of writing, the sites are still closed and passwords have been suspended.
"We are investigating an apparent attack on our servers that we detected this week," reads an email from the Harmonix team.
"The security of your Harmonix user information is very important to us. We’ve taken the sites down while we investigate this incident and determine how our systems and the information we maintain may have been compromised. At this time, we have not found that any of our users’ information has been published or misused. None of our sites maintain any credit card information, social security numbers, or financial account numbers for any of our users."
"As a precaution, we have disabled your Harmonix password. We’ll send you a notification when the sites are back up. When you log back in, we will require all users to reset their passwords. If you have been using your old Harmonix password on other sites, we recommend that you change those passwords too."
The take home message: change your passwords as soon as normal service is resumed. We'll bring you more on this story as it develops.
