Macs have always been susceptible to viruses. It's just that there are none that run on Mac OS X. Did you read the title of the article you linked? "New Trojans Use Old Tricks to Infiltrate Macs" A trojan is not a virus.Mac's finally susceptible to Viruses!?/URL]
Thoughts?
don't be fooled into thinking that you are protected by Mac OS X itself, which will ask for an administrator's username and password to install software. You won't see any prompt for credentials when this malware installs, as it is a userland Trojan.
Neither the /tmp/ nor /$HOME/Library/LaunchAgents folders on Mac OS X require root privileges - meaning that software applications can run in userland with no difficulties, and even open up network sockets to transfer data.
There have been trojans in the past that didn't require an admin password. It's nothing new.Sophos Naked Security Info on the Trojan.

Are Macs finally susceptible to viruses?
We always have been. The reason Macs don't get viruses is because there aren't hardly any... virus makers develop for Windows mainly. If A virus guy made one for Mac, it would do its job.
Any what? Viruses, virus makers, Macs?

If you're talking about Mac OS X viruses, there are zero, and there never has been one in the wild.Viruses. There aren't hardly any Full blown or even publicly known viruses out there that I know of.

And the Hacker could possibly install adware and spyware on your Mac.
So on OS X its not out of question for malicious software to get installed.
