Cyberwar storm clouds are gathering

CYBERSPACE. Some call it the new domain of war, after land, sea, air and space. The 2010 Stuxnet cyberattack on Iran's uranium enrichment plant, suspected to have come from Israel or the US, seemed to confirm this status.

Stuxnet raised the spectre of cyber-sabotage. The recently discovered Duqu trojan, which contains some Stuxnet code, is built to steal information about computers controlling industrial plants. IT security analysts such as Symantec suspect Duqu came from the same source as Stuxnet, and may be seeking vulnerable points for future sabotage.
