We've noticed that the slide showing the Stuxnet disassembly doesn't support Werner and Leder's comments regarding the worm and Windows 9x
It appears they misunderstood the code they were looking at. But another quote earlier in the story is more relevant anyway:
either the worm couldn't find any old Windows boxes, or perhaps the Iranian boffins were used to Windows 95 and 98 falling over anyway
Really, who would be surprised by a blue screen from a Windows 95 box?
