Sony believes hackers obtained user account information, including home addresses, email addresses, birth dates, usernames and passwords, in an attack that has shut down the PlayStation Network for nearly a week.
The hackers may have also stolen credit card numbers, though Sony says there is no evidence to suggest this. Credit card security codes have not been compromised
in either case.

Sony encourages all PSN and Qriocity users to be wary of scams, review account statements and monitor credit reports.
“We strongly recommend that you log on and change your password,” Sony said in a blog post that details ways to protect users against possible identity theft. “Additionally, if you use your PlayStation Network or Qriocity user name or password for other unrelated services or accounts, we strongly recommend that you change them, as well.”
The company expects to have both networks back online with at least partial service within a week.
