A Trojan horse program called “iBotnet,” which was first reported in January, targets Macintosh machines, but only those of users who download a pirated version of the iWork suite of productivity programs. So far, iBotnet has infected only a few thousand machines, in comparison with the Conficker.c worm, which has infected about 10 million computers running Windows.

Experts say that Mac users at large should not be alarmed by the Trojan, given the limited scope of the attack. The iBotnet program is called a “botnet” because the infected Macs become part of a network that is controlled by the author(s) of iBotnet.

The CNN article above gives several additional links about iBotnet. The article states that the technology research firm Gartner estimates that only about 7.4% of computer users use Macintosh (which, if you have been following this percentage for a number of years, is UP substantially!). :-)

One concern raised in the CNN article is that iBotnet may be an evolutionary step in malware for the Mac, upon which other authors of malware can build.
