Stuxnet

2010

First spotted in June 2010, Stuxnet is a new kind of worm aimed at industrial control computers running software from Germany's Siemens (SI). Its robust capabilities and a high concentration of infections in Iran led to speculation by security researchers in Germany and the U.S. that it had been created by a nation-state—the U.S. or Israel being the most likely candidates—and was aimed at sabotaging Iran's nuclear program.
