http://www.wired.com/threatlevel/2010/11/stuxnet-clues/ By Kim Zetter Threat Level Wired.com November 15, 2010 New and important evidence found in the sophisticated “Stuxnet” malware targeting industrial control systems provides strong hints that the code was designed to sabotage nuclear plants, and that it employs a subtle sabotage strategy that involves briefly speeding up and slowing down physical machinery at a plant over a span of weeks. “It indicates that [Stuxnet's creators] wanted to get on the system and not be discovered and stay there for a long time and change the process subtly, but not break it,” says Liam O Murchu, researcher with Symantec Security Response, which published the new information in an updated paper (.pdf) on Friday. The Stuxnet worm was discovered in June in Iran, and has infected more than 100,000 computer systems worldwide. At first blush it appeared to be a standard, if unusually sophisticated, Windows virus designed to steal data, but experts quickly determined it contained targeted code designed to attack Siemens Simatic WinCC SCADA systems. SCADA systems, short for “supervisory control and data acquisition,” are control systems that manage pipelines, nuclear plants, and various utility and manufacturing equipment. Researchers determined that Stuxnet was designed to intercept commands sent from the SCADA system to control a certain function at a facility, but until Symantec’s latest research it was not known what function was being targeted for sabotage. Symantec still has not determined what specific facility or type of facility Stuxnet targeted, but the new information lends weight to speculation that Stuxnet was targeting the Bushehr or Natanz nuclear facilities in Iran as a means to sabotage Iran’s nascent nuclear program.
