You won't be surprised by the reason: an attempt by hackers to "test a massive set of sign-in IDs and passwords" against Sony's network database. Some of the affected accounts showed "additional activity prior to being locked" and are being investigated. On the flip-side, Sony's Chief Information Security Officer, Philip Reitinger, stressed that most of the hackers' details resulted in failed logins and in any case credit card details are not at risk. Users are being told to expect an email if they've been affected, which will contain further instructions. Has Sony finally realized the value of timely communication?
