Hackers plan to blow up international trade

What the neutron bomb could not do, hackers hope malware will, judging from Wall Street Journal reports that Chinese, Russian and other cyber-spies have left viruses and Trojans all over the electricity grid, just in case of a hot war with the US.

Downtime reckons this could be the Pyrrhic victory of all time, seeing as knocking out the power would also knock out the internet, which we all now depend on, and then how would they be able to confirm orders for their oil and refrigerators to us? By yak-mail?

On the other hand, perhaps they were left by greenies who despaired that America would kick its CO2 habit.
