Bethesda posted on their blog today stating that over the weekend, their website suffered an attack from an external source.
Here is the post in full:
Over the past weekend, a hacker group attempted an unlawful intrusion of our websites to gain access to data. We believe we have taken appropriate action to protect our data against these attacks. While no personal financial information or credit card data was obtained, the hackers may have gained access to some user names, email addresses, and/or passwords. As a precaution, we recommend that all our fans immediately change passwords on all our sites — including our community forums and the statistics site we maintain for Brink players.
If your username/email address/password is similar to what you use on other sites, we recommend changing the password at those sites as well. As we don’t know what further plans the hackers may have, we suggest that you keep an eye out for suspicious emails and account activity.
We regret any inconvenience that these attacks on us cause for you. These attacks will be evaluated to determine if there are any additional protections we might take that would be prudent.
Just last week Epic, Codemasters, and Nintendo were among those that were hacked. It looks like we’ll be seeing a lot of this trend for a good while.
