Duane LaFlotte, the guy you want on YOUR side when it comes to hacking servers, has a great article on DevSource. In it he walks you through the devious mind of a hacker. The article required the following legal disclaimer "LEGAL DISCLAIMER: Please do not go hacking sites because "Duane told me to do it." I said, just look at the site, don't hack the site."

If you ever get a chance to see Duane and Patrick Hynds (both of Critical Sites which specializes in defending your networks) do their hacking presentation together, you really ought to try to see it. I'll have to find out where the next performance is.
