End of the Innocence?

Is this the end of the age of innocence for Apple users?

A malicious computer worm has been found that targets Apple Computer Inc.'s Mac OS X operating system, believed to be the first such virus aimed specifically at the Mac platform.

The worm is called OSX/Leap-A, according to a posting on the Web site of antivirus software company Sophos, which said the worm is spread via instant messaging programs.

The worm attempts to spread via Apple's iChat instant messaging program, which is compatible with America Online's popular AIM instant messaging program, according to the Sophos Web site.

Apple products have generally avoided being targeted by malicious code, virii, trojan horses, which is the bane of many PC users.

UPDATE:
Paul at Wizbang cautions that the article is quite poorly worded and uses the various malicious code variants interchangeably. So, while there may be problems down the road, the tech writers who supposedly know this stuff inside and out, are having problems of their own.
