They sort of have a point: The only reason they're able to do this (launch DDOS attacks) is because there are hundreds of millions of computers around the world that are infected with malware they are able to exploit. That's a huge general security problem that no one ever talks about--until PSN goes down for months.
These security failures, these threats and attacks are the only things that ever draw significant attention to cyber security.
The unfortunate thing is that that significant attention is seemingly not enough to get anyone to change their security habits.
American entities have been forced to up various components of their infrastructure because of groups like this--and yet American internet infrastructure is still way behind the rest of the world's.
That Asia's internet is so much better than ours is a terrifying prospect. What are we going to do when China decides to launch a real DDOS attack against large American networks--an attack empowered by, you know, fiber?
I'm not saying that Whatever Squad are heroes. I'm saying that, unfortunately, they're the villains American internet security needs.
