Reports indicate that someone has let loose a "Trojan horse" or worm for Mac OS X users. The program is hidden within a package that purportedly contains screenshots of Apple's as-yet unannounced next major revision to Mac OS X. Whether it's a Trojan horse or worm seems to vary depending on the source of the information. The code has also elicited a response from Apple, and a warning to its customers.
