Electronic Arts’ BioWare studio posted an Q&A answering questions about a cyber attack after sending customers e-mails detailing a hack on one of the company’s decade-old servers for forums supporting its online game, Neverwinter Nights.

The company said that information such as names, phone numbers, CD keys, usernames, encrypted passwords, e-mail and mailing addresses and birthdates may have been compromised, along with any other information gamers may have associated with their EA acounts.

“We immediately took appropriate steps to protect our consumers’ data and launched a thorough ongoing evaluation of the breach,” the company told customers. “We have determined that no credit card data was compromised from the servers, nor did we ever have or store sensitive data like Social Security numbers.”

The company automatically reset the passwords of all customers who may have been affected, and encouraged its customers to change any common usernames, e-mail addresses or passwords on other accounts.

No group has taken credit for the attack as of time of writing.

EA may be making a particular effort at assuring customers its networks are secure, having just launched Origin, an online gaming and mobile platform similar to Valve’s Steam.
