Tech News World: Stuxnet: Dissecting the Worm

"Security researchers are scratching their heads trying to determine the origin of the Stuxnet worm, a piece of malware that targets large industrial control systems. Judging by the way it's constructed, the information it targets and some of the organizations that have been hit, the worm may have been created by a national government. Others, however, have their doubts." ~ Richard Adhikari

Apparently this was a piece of malware that is two fold. One side was a Trojan while the other was a rootkit. Both are fairly nasty alone. This particular piece of malware was aimed at SCADA systems, which are basically infrastructure systems such as power, manufacturing, etc.
