Not exactly news. Macs have never been immune to this kind of threat, they're just significantly harder to exploit successfully compared to Windows.
And if you look at the article, they state that the threat level is low, someone would have to actually install this on the system while sitting at the computer.
I'm not really sure why this is even news. It's a very low level threat. Wake me when someone develops a "drive by" installation method like you frequently find with Internet Explorer on Windows. When little to no user interaction is required, you'll know it's time to start shoring up the castle defenses.
