The ICO found that the company was to blame for security failings and that the hack could have been prevented. According to David Smith, ICO's director of data protection, Sony stored a lot of personal customer information and "should have known better." Smith said the security measures in place "were simply not good enough." Sony said it plans to appeal the fine. In a statement, Sony said it was the victim of a "focused and determined criminal attack" and that the personal data accessed is unlikely to have been used fraudulently. The hack exposed personal data of about 100 million PSN accounts and resulted in the shutdown of the network for several weeks. At the time, Sony apologized for the incident and offered a "Welcome Back" promotion that included free games to PSN users. The chatter on Main Street (a.k.a.
