and you know this how?
Because most major infrastructure existed well before the internet and is not dependent on it in any way shape or form. The technology is often simply not that sophisticated, they can simply unplug whatever connectivity exists and get things back up again should any attack cause an issue. Besides how stupid would you have to be to have mission critical infrastructure dependent on the web with no redundancy. You think they are actually that silly?
if cyber weapons are capable of messing with the PLC controllers that manage centrifuge speeds inside a nuclear plant then they are capable of messing with all sorts of control systems. the future is here now believe it or not, its far beyond a case of "lol my windows box got hacked", we're talking electricity grids, power plants, transport systems, water management, telecommunications systems and any other piece of critical social infrastructure you can conceive of being vulnerable to engineered and targetted cyber weapons.
LOL... only if they run windows, which the Chinese don't.
Like I said causing problems is one thing but disabling is another thing altogether. The future was here a while back... and these issues have been thought through, trust me.
they don't need to invade, occupy or even land troops on the mainland. there's no point occupying china, just ruin their infrastructure and let it collapse under its seething mass of humanity. but the whole china vs US armchair general games are just theorycrafting and is purely a matter of opinion so lets not get into a 10 page diatribe ridden derail on what if's.
Yeah look, you are severely overestimating the damage they can do and underestimating the ability to recover. They have a good level of redundancy in major infrastructure and can normally operate in isolation if needs be. Anyone with any sense would make sure this is the case, to think that they would allow national infrastructure to completely vulnerable is a cyber fantasy. The cyber security industry are great ones for over selling the threats.
anyway the US is setting up the arab world for its next world war. the arab spring will lead to islamist takeovers throughout the middle east and voila, instant enemy! /tinfoil hat
start with this really good article and google the rest to your hearts content.
They assume that Stuxnet destroyed about 10% of Irans centrifuges, not quite what you call disabling but certainly a disruption, which is what I reckon is the most they would achieve. For a cyber attack to be effective it would have to be a part of a strategic offense that involves other forms of attack that take advantage of whatever outage the cyber crew can create.
