I just picked up a comment made today on a post Randy made about the comparative security of Macs and PCs. Since the original post goes back to 2006, it seems a pity to bury the comment on a page most people won't get to.
In fact, since the comment reproduces an article in PC World, we can't really reprint it, but it's certainly worth looking at the original article, if you're interested in Mac security.
Briefly, the story is about the efforts of Dai Zovi and Charlie Miller to add utilities to the Metasploit toolkit that will "improve" its value to researchers interested in OS X exploits.
