Malicious Distributed Computing
Jeremy Erwin writes "In this whitepaper, Brandon Wiley suggests a possible design for a "superworm", a coordinated network of worm nodes. Typically worms are designed to infect as many hosts as possible, but as overly rapid growth can lead to early detection, this is a suboptimal strategy. The worm, dubbed Curious Yellow uses communication between worm nodes to ensure optimal infection rates."
if you meet the virus during distribution, kill it.
Infect hosts, get them all in something like an IRC channel, give the signal....
Just wait until that kind of worm goes out... :)
