After way too many hours of experimentation, we have just posted a writeup of our findings to the Macworld site: http://www.macworld.com/news/2006/02/17/leapafollow/index.php This isn't a technical analysis, as Andrew Welch of Ambrosia has done, but rather, a user-centric analysis: what happens when Leap-A is installed on a system. How do apps get infected? How does it try to spread? How do I get rid of it if I do have it? We found a few surprises, including the fact that the iChat spread is limited to Bonjour networks, and that only apps you own are infected. As others have pointed out, it takes some effort to get this thing on your system, and it won't spread on its own. Still, it serves as a good reminder to be aware of what you're downloading and installing. Sometimes, being the first to grab that latest shareware app may not be a good thing! :) -rob.
