Of course there are still OSX.2.1 boxes out there... but I could write a virus that infects Windows 95 also... We are not talking about unupdated operating systems here. You keep changing the heighth of the bar... virus, now exploit, now exploit on one build of an early release...
Actually it is you that keeps changing the bar. Early on you acted is if Mac was invincible. Just go back and read it. Now that you finally see the vulnerability, you go back to parsing the challenge. As far as virus vs. exploit. I'm sure the grandma that has a hacker control her machine doesn't care if it was a virus or an exploit. It's all the same. But if you read my earlier comments that exploit is pretty easily changed to a virus. Just script the exploit to install itself on the mac and now it will attack other machines trying to update.
Also I'm not the same guy you're referring to. I didn't mix your name up until after you changed my screen name. So I guess as you try to point your finger, you end up with 4 pointing back at you.
I'm not going to rahash what is already posted. Just re-read the entire thread and you'll see where you act as if OS X is impossible to exploit via a virus. I've proven it can be done and now you say well it doesn't count because it's an old flavor (although it's still out in the field).
