Now, having said that, Siemens and other industrial controls builders use Windows (I presume Windows CE) because HMI devices (which are sometimes also PLCs) are becoming highly graphical in nature, and it becomes easier to develop system screens with "drag and drop" technology than it is to try and code those screens in hex. If the user wants a screen changed or added, it's a 30 second affair instead of an 8 hour task.
The article does not say that this worm had anything to do with Windows, only that the Siemens HMI device was running Windows. It did say that someone had to duplicate a Siemens industrial network to research the worm. What this means to me is that the worm was developed to spread over one of the proprietary industrial networking protocols, probably by someone with some decent Siemens experience.
