First virus for Apple Mac OS X found: OSX/Leap.A

The virus, named OSX/Leap.A (also known as OSX/Oompa-A) spreads via instant messaging systems. The OSX/Leap.A worm spreads via the iChat instant messaging system, forwarding itself as a file called latestpics.tgz to contacts on the infected users' buddy list. When the latestpics.tgz archive file is opened on a computer it disguises its contents with a JPEG graphic icon in an attempt to fool people into thinking it is harmless. And oh yes, I can confirm that this virus is not heavily in-the-wild yet as Apple Mac OS X is not commonly used in Europe and some other parts of the world.
