The leaking of 77 million PSN account has attracted the attention of The U.S. Department of Homeland Security and FBI. The personal data that may have fallen into the hands of hackers are likely also will expose other external data, such as business and financial information, and government institutions information.
As reported earlier that Sony states that the possibility of user data such as name, address, date of birth, email address, login name and password may have been leaked because these data are not encrypted in the PSN network itself. Even so the Sony states that the Credit Card data is stored encrypted, and there is no evidence that these data has leaked, but of course it does not make things better.
Good news for users of the PSN is that Friends Lists and PlayStation Trophies are expected to remain intact when the service return.
