From slashdot earlier today:

“Numerous Stuxnet related stories continue to flow through my bin today, so brace yourself: Unsurprisingly, Iran blames Stuxnet on a plot set up by the west designed to infect its nuclear facilities. A Symantec researcher analyzed the code and put forth attack scenarios. A threatpost researcher writes about the sophistication of the worm. Finally, Dutch multinationals have revealed that the worm is also attacking them. We may never know what this thing was really all about.”
