I'm interested in this challenge as well, but also have some concerns. I actually find the idea of playing a real malware very attractive, but my understanding is that the people who do this usually do it in isolated environments on boxes that can be wiped and reloaded from scratch. I am not in that position. As interesting as it is, I really can't risk jacking one of my machines.
I am also concerned about the statement above that the software only runs on Windows XP. I don't have an XP box anymore.
I guess I could install it on my GF's dad's computer. It is XP and he installs malware on a regular basis anyway.
