Found this news over at macintouch Opener, a new report, covers in much more detail the Mac malware noted yesterday. It's a very nasty piece of work ("rootkit"), designed to surreptitiously "crack" and control your computer, using Mac OS X features to maximum advantage and hiding from such programs as Little Snitch. It may not yet have an effective way to infect other Macs across a network, and may not yet be widespread "in the wild", but it's craftily designed to extract and transmit critical information from any computer on which it runs. Readers describe the program's origins and offer tips for identifying it. Don't know the accuracy of this, but it sounds like it could be the first real example of a mac virus.
