It's E3 week and that means that top executives make the rounds to as many media outlets as possible. Sony's Kaz Hirai is no exception, speaking to a number of publications in North America and Europe this week. In an interview with the BBC, Hirai admits that Sony has not been able to catch whoever breached the PlayStation Network's security in late April, and it is not exactly sure what they might have taken. All they really know is that they accessed user data and took some of it.
".. With regard to the 100 million [compromised] accounts, we do know the information was accessed, we don't know however what part of the 100 million accounts were taken from our servers," Hirai told the BBC. "For example, it might be 100 million first names, it might be 100 million last four digits of a phone number, it could be the entire account information, we just don't know, but I think the people that intruded our systems were very good in hiding their tracks as they left our systems, so we may not know for a very long time or we may never know."
Sony has fully restored all of its services, excluding Japan, and claimed during e3 this week that activity on the PlayStation Network was back up to 90 percent of what it had been before the security breach.
