So the last one we successfully managed to isolate, our customer they had more than one PC with multiple infections. It’s not Playstation’s, but Windows machines that are infected with I assume some malware that is trying to log into PSN.

So I should try again to get them to tell me what an "Account Takeover Attempt" is? They ignored my last request.


It's easy to explain DMCA or spam to an end-user, but it's difficult to explain to some soccer mom that her kids are doing something to make Sony mad, when I can't explain to them what Sony is mad about.
