F-secure Q&A analysis of stuxnet computer worm effects Siemens Process Controllers

Apparently the stuxnet worm did most harm in the ultra-centrifuges plant at Natanz in Iran.

(New York Times) - In early 2008 the German company Siemens cooperated with one of the United States' premier national laboratories, in Idaho, to identify the vulnerabilities of computer controllers that the company sells to operate industrial machinery around the world -- and that American intelligence agencies have identified as key equipment in Iran's enrichment facilities.

Siemens says that program was part of routine efforts to secure its products against cyberattacks. Nonetheless, it gave the Idaho National Laboratory -- which is part of the Energy Department, responsible for America's nuclear arms -- the chance to identify well-hidden holes in the Siemens systems that were exploited the next year by Stuxnet.
