Hackers are reportedly sticking virtual razor blades into Apple computers this Halloween, as a Mac security vendor reports Wednesday that a Mac-focussed Trojan is reportedly loose on the internet costumed as an innocent video decoding file.

Mac OS X users visiting malicious porn sites are told to download a special codec that will let Apple's Quicktime player to play the porn flicks, but instead of adult treats, users get a malicious trick, according to anti-virus vendor Intego.

I can sum it up in one sentence: OS X is the new Windows 98.
