writes "I am not an expert with internet worms like Code Red. However, I am curious if it would be possible to create a friendly worm/virus/whatever that would fight the original by using the same security holes. For instance, I read that Code Red II opens a back door. Why not have another virus that exploited the back door, closed it, then started sending itself to other servers for a certain period of time? "
The submittor raises an interesting question - is this possible? I would guess so, in theory. And while we're working on Code Red, can we send a large man to the home of my latest Sircam senders and politely "ask" them to stop clicking on virii?
