Yeah, I know, I should have used MP3 or Ogg, but CDex wasn't working for me at the time, and I was lazy; I've since rectified the transgressions).

      It's not that it's being exploited by genius so much as it was implemented by arrogance. The very nature of DRM software is to conspire with a content provider to use Joe User's computer against him in a way that he cannot circumvent.

      Any DRM implementation is more likely to be exploitable in ways such as this. DRM is more likely to be insecure from the user's standpoint because it's designed from the ground up with somebody else's security as the highest priority. And once the software has been exploited, it has the potential to be highly troublesome because the malicious code now has access to a system that was designed to prevent the owner of the computer from tampering with it. The more effective the DRM is, the more dangerous it is to the user.

      You are incorrect. This exploit has nothing to do with fetching codecs. It is a feature that will open a web page specified by the creator of the movie or song file, that is intended to allow the user to buy a license to use the media. Basically it is a "feature" whereby media player will see a movie, notice you don't have a DRM key for it, and open a web page so that you can buy said DRM key. Unfortunately, like usual MS was completely blinded by dollar signs and did not consider that arbitrary files could direct the user to any old web page, and since IE is full of holes, this makes it pitifully easy to use a media file as a trojan.

      I have not looked at this exploit more than superficially so I am unsure if the media player will always open the page in IE, or if setting Firefox as your default browser will save you. I also do not know with what privilege level IE connects, at a guess I would think it is as you with the lowest security setting for that page, but it could be your default, or connect as "root."

    The loophole in the Windows Media DRM process allows companies to create media files and link them to adware. When you normally download a protected Windows Media file, you also receive a license that lets you play it. If however Windows Media Player cannot find a valid license on your PC, it checks in with a remote system running Microsoft's Windows Media DRM Server.

    You should rarely see that happen. Some files, however are set up to ask you for information before playing. They do this by displaying a URL in a dialog box labeled License Acquisition. Normally that dialog box is used to check for a user name or offer a chance to purchase the file that's being played. In a legitimate DRM-encrypted file the author may let you play it a few times, then bring up a window asking if you want to buy it.

    Since the license dialog box is in essense an Internet Explorer window, it will display whatever is on the page it points to, in the cases that have been seen of this these trojaned Windows Media files, they all point to servers that load up unwanted ads, including windows that attempt install adware onto your PC surreptitiously, including adding items to your browser's Favorites list, attempting to change your home page and installing viral adware such as the 180search Assistant.

But Windows asks explicitly if you want to download and install the software. You get a warning, you have to say, "Yeah, I want that piece of malware."

It doesn't need to.

    To my knowledge Linux doesn't have a good solution to that problem, either. If you need software to play that movie/music, it's up to you to verify that the software isn't malware. Linux users escape this problem largely because there aren't enough of them to make it worth the malware writer's effort (as well as the fact that Linux users tend to be better educated and would answer "Hell no!" to the question if asked).

Download the codec but don't give it permission to do anything except take stuff from one place in memory and dump it to another, or access a limited direct-to-video API. No network access, no disk access. I'm not aware of any particular Linux security sandbox.
