As long as the lights were still on, though, the geek squads stayed focused on trying to figure out exactly what this worm intended to do. They were joined by a small citizen militia of amateur and professional analysts scattered across several continents, after private mailing lists for experts on malicious software posted copies of the worm’s voluminous, intricate code on the Web. In terms of functionality, this was the largest piece of malicious software that most researchers had ever seen, and orders of magnitude more complex in structure. (Malware’s previous heavyweight champion, the Conficker worm, was only one-twentieth the size of this new threat.) During the next few months, a handful of determined people finally managed to decrypt almost all of the program, which a Microsoft researcher named “Stuxnet.” On first glimpsing what they found there, they were scared as hell.
An interesting (not too technically-intimidating) look at the American(?)/Israeli(?)/Iranian(???) piece of mischief besetting the world's computers (or some small subset thereof).
