Manus, not sayin anon is involved (nor have I ever), but you can't really claim with certainty that everyone involved with the group had nothing to do with it considering only an idiot would admit to this and take responsibility. Now it's just as, if not more, likely that the culprit was either smart or lucky enough to time this with anon's various threats to Sony so far. In fact, I'd put my money on that simply because this is a more sophisticated attack than anon are known for.

Either way though, it really doesn't matter at this point to customers who did it as much as it does taking steps to protect themselves.
