Sony said Wednesday the personal information on all 77 million users of its PlayStation Network services around the world may have been accessed by a hacker, potentially including credit card numbers. Sony called on users to regularly monitor their credit card bills.
Sony said it ”cannot rule out the possibility” that credit card data was compromised as a result of the breach. The affected systems are the online network for PlayStation game players and the music and video service Qriocity. This is possibly the worst-ever case of an information leak involving a Japanese company.
There is no evidence so far that credit card information was leaked, but Sony urged users of PlayStation Network or Qriocity to change their user names and passwords of other digital accounts if they are the same as those for the Sony services.
