Let's be very specific: They only people who would thank anyone for such a stunt would be the clueless admin who can't install the patch on their own. Now, obviously, there are lots of those. OK, cut to the chase, here's my list of reasons hy this is bad, to be trotted out whenever someone suggests a "nice" worm: -What about the traffic it takes up? -What about the boxes that don't patch properly, don't make it back after reboot, or took down etrade in the middle of a trading day? -How does your worm know when it's done? -Maybe I don't want my box patched, the patch broke my app -How do I tell your good worm apart from the original bad worm, or the other worm which looks like the good worm, but is really a bad worm? -How about people like us who track attack data, and you just skewed the heck out of it? When does www1.whitehouse.gov get to come back? If there's still *A* worm around on the 1st, which one is it? -Do we really want an Internet-sized game of corewars? -Why stop at patching? Don't clueless NT admins deserve to have the hard drives reformatted until they learn how to apply patches? (and if you're no good at spotting sarcasm, please be sure to send me flames.) Having done my usual lecturing, I will say that this is the first time I've even been willing to entertain the idea of a good worm... I just don't know what else can fix a problem of this scale. You will never, ever come to agreement on how it should be done. Either some government will decide for you, or some hacker who is willing to take one for the team. I'm not real comfortable with either of those two setting policy for the Internet. Ryan
