“Stuxnet”, the cyber virus which attacked the Iranian Bushehr nuclear plant, has hit China as well. Already 6 million single-user computers and 1,000 business computers in the “Celestial Empire” have been infected. The danger presented by Stuxnet consists of its ability to infiltrate in large industrial facilities, such as the German industrial colossal Siemens, allowing the authors of the virus to assume control of key systems such as pumps, motors, alarms and valves.
