Sony has issued an official statement on the recent PlayStation Network downtime attributing the issues to the “possibility of unauthorized access to personal information on the PlayStation Store through PCs.” Sony indicates that a small possibility that password may have been changed, making it possible to view personal information and use the PlayStation Wallet.
“PlayStation Network accounts do not display entire credit card numbers, so any unauthorized access to your PlayStation Network account is very unlikely to compromise your credit card number,” Sony said.
We have taken immediate measures to rectify this issue and system security is restored.
We have investigated the extent of unauthorized access and possible alteration of passwords that could have occurred before corrective measures were taken, and are directly contacting customers who may have been affected by this incident. In order to verify that your account is intact, we strongly suggest that PlayStation®Network users sign in to the service. If you can successfully sign in with your pre-set password, your account is not affected by this incident.
Im glad I wasnt affected!
