Stuxnet's Secret Twin (4,176 words)
by Ralph Langner, Foreign Policy
Stuxnet is a pretty nasty nasty customer, especially if you happen to be a centrifuge used in the enrichment of uranium. Amazingly, the story of the first publicly acknowledged cyber weapon keeps getting more and more interesting. Ralph Langner has spent the last several years poring over code and other details of Stuxnet's history and discovered there was an earlier version of the virus, that was even more destructive than the one unleashed on Iran's nuclear facilities. Instead of putting the centrifuge's motors in overdrive, it over pressurized them by closing valves designed to allow gas out. It sounds like a perfectly logical avenue of attack, until you realize that the potential for truly catastrophic failure would have quickly blown Stuxnet's cover.
