As for the leak itself, Sony says that all personal data was not encrypted but was located "behind a very sophisticated security system" which apparently was unable to prevent the infiltration. Credit card data was encrypted and there is still no evidence that such data has been stolen. That's according to Sony, of course, and it goes against the numerous stories that have surfaced about sudden credit card fraud, including an incident with 1UP contributor Steve Watts. It's possible these occurrences are coincidental; it's difficult to say with any degree of certainty that they are a direct result of the PSN breach.
