And that's why it's a good idea to research the bacteria/moulds etc which live in and near Chernobyl. Life 'finds' a way, and thanks to the random changes/evolution of the lifeforms there, some very interesting and potential mutations can have popped up there.

We'll have to go look, though.

Brandon Wiley proposed a scenario in which a future internet would be consumed by the warfare between several (black or white) worms that feature node-coordinated efforts to prevent detection and removal. For those too lazy to read the link, "Curious Yellow" is basically a modular worm in which zero-day exploits can be added as they are discovered allowing for unchecked growth across the 'net. The worm can then work with other nodes to attack targets by dropping all their traffic, or by subtly modified whatever they receive. The best way to fight such a worm is with fire, a similarly designed "white" worm that goes around patching hosts as quickly as it can.

IMO, remote exploits are rare enough that I don't see this ever happening. On the other hand, with enough infected bot nodes to work with the data mining potentials of some of the more sophisticated extant work networks does worry me...
