A PR story? Those are usually meant to give good PR, not make your platform look insecure and unstable. I don't see how it would be in Sony's interests to pretend the widely publicized Amazon outage had nothing to to with its problems and instead make up a story about how its security had been breached.

We may see it differently, from my point of view its much easier for Sony to blame this on anon as a) there is a known conflict already and its very simple to point the finger b) it hides the fact that a critical part of there system is on a 3rd party service with no contingency plan / backups..

I haven't read anywhere about security breached all I've seen is DDOS and thats exactly what anon are known for.
