I can't think of any examples in the defense side of the house, but certainly viruses can exhibit these emergent properties. The slammer worm did nothing explicitly malicious to any machines. It spread in memory only, not touching disk, and did not attempt to phone home or otherwise do explicitly malicious actions. However, it did take down much of the internet, in what, 11 minutes? The emergent result of it's spread was catastrophic failure. Based on what I understand of emergent behavior, this fits the bill. I'd be interested to hear if you disagree. Viruses communicating with one another, autonomously, would be a very interesting area of study. I believe some vague doomsday articles are out there on this topic. cheers, tim _______________________________________________ Full-Disclosure - We believe in it.
