In June 2010 a security company VirusBlokAda detected this [[malware]] and gave it the name "Rootkit.Tmphider."<ref>http://www.wilderssecurity.com/threads/rootkit-tmphider.276994/#post-171213</ref> Symantec then named it "W32.Temphid," but later changed the title again to "W32.Stuxnet."  Unlike some other malware like [[Conficker]], Stuxnet did not give itself a name.  Instead, the name was derived from common references in the worm. The first part of the name, "stu," comes from the ".stub" file extension, and the second part, "xnet", comes from the "MrxNet.sys" file.<ref>http://www.abc.net.au/science/articles/2011/10/26/3348123.htm</ref>

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 five [[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.
