Five questions for Sony about PSN breach

[KeepItReal]

After a week of PlayStation users wondering why they couldn't access PlayStation Network, Sony dropped the bomb yesterday: someone had gained access illegally to the personal information of more than 75 million of its users, forcing the company to shut down PlayStation Network and rebuild it, along with the related media download service Qriocity.

Sony had issued a few brief updates late last week and over the weekend acknowledging the service's outage and then an "external intrusion," but it didn't explain the consequences until yesterday.

The information exposed includes customer names; addresses; e-mail addresses; birthdays; PlayStation Network and Qriocity passwords and usernames; as well as online user handles. Sony says there is "no evidence" that credit card information was compromised, but the company advised customers to monitor their credit cards for erroneous charges anyway.

Who did this and how were they able to access our information?
Why did it take a week to inform customers their credit card information may have been exposed?
Have you contacted law enforcement?
How is Sony compensating customers?
