My good friend, Jesper Johansson, just did something that's really hard to do - make the front page of www.microsoft.com, with his "Anatomy of a Hack" paper. Go take a look...

In a few days this'll be replaced with something else, in which case, you should go direct to the paper http://www.microsoft.com/technet/technetmag/issues/2005/01/AnatomyofaHack/default.aspx
