The writer of this [[malware]] is not known, but the complexity of it and the amount of research which went into it suggests to most that it was designed by an organization or government. It uses not one or even two but a total of four [[zero day exploits]] (vulnerabilities which had not yet been found) which implies a powerful entity was behind it.<ref>http://www.symantec.com/connect/blogs/stuxnet-using-three-additional-zero-day-vulnerabilities</ref> Since the [[United States]] and [[Israel]] would probably be at the greatest risk if [[Iran]] does achieve nuclear capabilities, it is generally suspected that one or both of these governments where involved.
