Macs have a completely different OS structure than PCs. Isn't that what has saved them from all the viruses that have been written for and have plagued Microsoft users for all these years? i.e., copy this or that file to windows/system folder. This malware would appear to know Macs. I agree with some previous posters. I always thought that either there weren't enough Macs for the evil little 16 year olds that sit in their bedrooms and write viruses to be interested in or that they were maliciously written by Apple-snobs out of envy.

The malware is written for OS X, but still requires a user to intentionally install it.

I mean, I could write a program in about 5 minutes that starts deleting files anywhere on a machine, for pretty much any OS you can name. The trick would be in getting someone to install it and let it run.

> Macs have a completely different OS structure than PCs.

There are three main lines of attack on any computer:

1. The Operating System
2. The Applications (apps have software bugs more than OSes because they change more and faster)
3. The User (i.e. social engineering attack)

The operating system under Mac OS-X is Unix. It's the most secure OS in common use, period, having been around for about three decades and well-debugged. It's the standard for OS security, this side of proprietary DOD embedded OSes.

Application attacks are easier, but apps are a moving target.

Most attacks, and so far, ALL Mac related attacks, go after the User, who is the weakest link.

No surprises there.
