Gamespot also reports that several financial companies, including MasterCard, WellsFargo and American Express, have witnessed "no unauthorized activity relating to Sony."
Sony's Patrick Seybold passed along the positive news: "The entire credit card table was encrypted and we have no evidence that credit card data was taken. The personal data table, which is a separate data set, was not encrypted, but was, of course, behind a very sophisticated security system that was breached in a malicious attack."
Sony's PlayStation Network is still offline while it's rebuilt with a higher level of security. The company saw its shares drop 4.5% today on the Tokyo exchange to $27.71.
