So far, there has been no proof that the worm exists or even works. The "guy?" has been criticized, not just by Mac fans, but security professionals and even newspaper reports for being irresponsible. Then supposedly, as a security expert and researcher, the "guy?" has his website hacked, the decides to pack his bag and go hide. But not before spreading a ton of misinformation and accusations. All just enough to keep people in a tizzy, and legitimate his claim as a Mac OS X author, when he still hasn't provided proof.
I say the title should read, "Author of the Alleged Mac OS X Worm, Claims Death Threats" It's far more accurate.
