Mac users who practice unsafe hex will find more than they bargained for.
From Intego:
Exploit: OSX.RSPlug.A Trojan Horse
Discovered: October 30, 2007
Risk: CriticalOSX.RSPlug.A Trojan Horse Changes Local DNS Settings to
Redirect to Malicious DNS ServersDescription: A malicious Trojan Horse has been found on several pornography web sites, claiming to install a video codec necessary to view free pornographic videos on Macs. A great deal of spam has been posted to many Mac forums, in an attempt to lead users to these sites. When the users arrive on one of the web sites, they see still photos from reputed porn videos, and if they click on the stills, thinking they can view the videos, they arrive on a web page that says the following:
Quicktime Player is unable to play movie file.
Please click here to download new version of codec.
After the page loads, a disk image (.dmg) file automatically downloads to the user’s Mac. If the user has checked Open “Safe” Files After Downloading in Safari’s General preferences (or similar settings in other browsers), the disk image will mount, and the installer package it contains will launch Installer. If not, and the user wishes to install this codec, they double-click the disk image to mount it, then double-click the package file, named install.pkg.If the user then proceeds with installation, the Trojan horse installs; installation requires an administrator’s password, which grants the Trojan horse full root privileges. No video codec is installed, and if the user returns to the web site, they will simply come to the same page and receive a new download.

Commentary: Mac trojan overhype? You tell me.
Well, we knew it was coming, Apple users may get hit hard now if the malware gangs are targeting.
Vnunet.com UPDATE: McAfee has confirmed the OSX.RSPlug.A trojan and reported that it is spreading through fake codec sites in addition to the porn website.
