That may be the answer to your question right there. It happens on Windows systems every day; it's not news. It has to be something interesting like Morto which is special because it uses DNS for command/control and does not currently exploit a code vulnerability to propogate (it just tries to log in like any other remote terminal user would).

Apple gets it pretty bad too. Every blunder that conflicts with the Apple utopian marketing message.

I'm actually surprised by the lack of "nah nah" comments by other OS fans.
