Sony has warned last month that hackers stole password, birthday and other data about users of its PlayStation Network that connected PlayStation 3 (PS3) consoles to online games, films and more.

PlayStation Network and Qriocity streaming music service were turned off on April 20 in the wake of an "external intrusion,"  Sony spokesman Patrick Seybold has said at the time.

While the cyber attack is still being investigated, Sony said it believed that PlayStation Network and Qriocity service users' names, addresses, birthdates, passwords, and email addresses were swiped.

"While there is no evidence at this time that credit card data was taken, we cannot rule out the possibility," Sony said in an email message being sent out to PlayStation Network and Qriocity users.

"It is also possible that your profile data, including purchase history and billing address (city, state, zip), and your PlayStation Network/Qriocity password security answers may have been obtained."

Sony shut off PlayStation Network and Qriocity to investigate the breach and bolster defenses.

"We have a clear path to have PlayStation Network and Qriocity systems back online, and expect to restore some services within a week," Seybold said.

Players were still able to take part in games offline on consoles, but lost the ability to challenge others on the Internet, stream movies, or get other services.

PlayStation Network launched in November of 2006 and boasts about 75 million registered users worldwide.

Millions of accounts all over the world were hacked.
