There is now a "cyber super weapon" designed to destroy a specific real-world target, The Christian Science Monitor reports in a fascinating piece:
The cyber worm, called Stuxnet, has been the object of intense study since its detection in June. As more has become known about it, alarm about its capabilities and purpose have grown. Some top cyber security experts now say Stuxnet's arrival heralds something blindingly new: a cyber weapon created to cross from the digital realm to the physical world to destroy something.
At least one expert who has extensively studied the malicious software, or malware, suggests Stuxnet may have already attacked its target and that it may have been Iran's Bushehr nuclear power plant, which much of the world condemns as a nuclear weapons threat.
