Stuxnet More Subtle than First Thought?

Remember the flap over Stuxnet? The alleged computer worm that may have deliberately targeted the Iranian nuclear program? (If not, click the link.) While the usual suspects (the US and Israel) plead that they know nothing (nothing!) this report in Wired suggests Stuxnet was a very subtle program aimed at introducing gradual, undetectable changes into a system.

The technical details are way beyond me, so I merely refer you to the article, since we've dealt with this story before. It does sound increasingly like Iran may have been the target.
