Sony executives also apologized for the breach, and they're conducting a thorough and ongoing investigation into the matter and once the PlayStation Network is restored online, users will have to change their account passwords before being able to log into the service. The update will require users to change their passwords on the PS3 on which the account was activated, or through e-mail validation.
To thank customers for their patience and loyalty, Sony announced they would offer PlayStation Network users 30 days free membership in the PlayStation Plus service, which provides access to exclusive games, beta trials for games and other nice stuff.
Current subscribers to the PlayStation Plus service, don't worry. You will receive an additional 30 days for free. :)
