I find this whole thing to be questionable. This "virus" is supposed to attack PC, Mac, and Linux. Yet there is almost no information on how it did this. There were some routers attacked as well. If this attacked Mac it would be all over the news, and are far as Linux, which Distros were attacked.
I al going to rate this one up there with the Y2K scare.
The end result may be over-stated but the threat is real. As far as I know Mac and Linux should be fine. I work in the IT world and have spoken to many experts about this and all agree it is very real.
