Wouldn’t it just be cool to be the first and wipe out an entire talking point?
Not really. The virus here can be done easily on any machine that someone idiot is willing to steal programs and install them not knowing if they had a virus or not.
The talking point you are referring to is being able to attack a Mac over the wire without the need of a user installing a trojan. And that was already defeated with the first version of Mac OS X when the man in the middle attack was found to be viable against their update website.
Once again Mac is just too small a footprint to worry about.
It might be the first time, but a second time... then it isn’t the first!
