on the PlayStation Blog, and while some information it contains seems to reiterate things we already know -- "some services" will return within a week, you should monitor your credit card(s) -- new details have been brought to light.
First off, Sony is "working on a new system software update that will require all users to change their password once PlayStation Network is restored." It's also been confirmed that PSN is being physically rebuilt as a result of last week's intrusion. SCEA PR director Patrick Seybold states in the FAQ that the company is "moving our network infrastructure and data center to a new, more secure location, which is already underway."
Also revealed: While "the entire credit card table was encrypted" and there remains "no evidence that credit card data was taken," PSN's personal data table "was not encrypted, but was, of course, behind a very sophisticated security system." Not sophisticated enough, apparently.
