First trojan horse or worm reported for Mac OSX

From MacWorld, the first trojan horse or worm is reported for Mac OSX. Should the Mac ppl be alerted?

Well, the trojan horse/worm has not yet to be determined as a disruptive virus yet. It just spreads itself thru the bundled chat program iChat in Mac OSX. No real damage to data or anything being detected yet from it. So I guess we dont need to be alerted yet.

Well, I guess with the recent attension Apple is getting for it's iPod and the Intel iMac, Macbook Pro series, ppl are really expected Mac OSX could be the next big thing. That's y hackers are starting to develop stuffs like virus and worms for the once virus-free OS.

Beware Bill Gate! Apple is coming!
