There is some interesting commentary on The Register and even better detail on ">Light Blue Touch Paper about a proposed ban in the UK against dissemination and the eventual use of hacking tools. So if you run a site out of the UK with worm code on your site, that can be used to commit a crime, you should pay attention to whether this law is passed or not.
I suppose it’s not dissimilar from putting a handgun in a schoolyard although it’s really hard to tell intent in either case. Often times the research done on this site and others of it’s kind are academic and are helping to solve the problems. Granted that same information can empower less scrupulous types, so that’s at least partially the intent of the law. However, I would bet money that this does little, if anything, to stop the proliferation of exploitation materials. This will no doubt simply force hackers to move their equipment offshore or go more underground - which could be bad for investigators, and for researchers alike.
