The thought that a few, decently intelligent , disgruntled *individuals* , coupled with the 'destructive' nature of the attacks I think scares the crap out of govvies. Call it cyber-vandalism, -terrorism, or -war, the act of public destruction and 'outing' is what has made this attack a 'game changer.' State funded threat actors have been spying for years. They've mostly - the stuxnets aside - have stopped short of destruction that they're all capable of, and 'just' xfilled credit cards, or secret formulas.
Think what the Target attackers could have wrought by bricking the POS terminals.
So if you're a govvie, it's natural to presume that a whacky - but funded - state threat actor is behind this, as the thought of a handful of individuals is just too scary.
Do any /. ers know what security product stuff that Sony deployed (which missed all of this )? I'd love to know their host based AV and HIPS, and their network FW, IPS, 'APT ' detectors/protectors.
