The story behind Stuxnet, the malware targeted at an Iranian nuclear processing station, has been known in general since last fall when a team of researchers at Symantec released this document, which we covered at the time in our article here. But seeing is believing. I had a chance to attend a special briefing at Symantec’s headquarters in Mountain View, Calif. where Patrick Gardner, a director in their security group, actually showed us what was involved. It was a real thrill.
