Well over at Doom forums , where they discussed the previous versions, there is talk about a new tool for uncovering the individual keys from Microsoft’s DRM blackbox components (“IBX”), up to version 11.0.6000.6324 , that will work with Vista and newer versions of the media player (v11?) and Zune software. It has also been convirmed to work with Vista 64 as well.
The person writing about this has the name Divine Tao and says they have nothing to do with the original hacker Viodentia (which recently Microsoft dropped charges as they could not find the person), strangely if you mix the letters in Divine Tao, you get Viodentia!
fairuse4wm is at v1.3fix2 and all details are at Doom.
