Zune DRM cracked again

Abdul sez, "A new version of FairUse4WM v1.3 Fix2 from Doom9 is available that claims to remove the DRM license protection from songs and music downloaded from Microsoft's Zune Marketplace allowing you to play them on any portable media player."

This post introduces a new tool for uncovering the individual keys from Microsoft's DRM blackbox components ("IBX"), up to version 11.0.6000.6324. Lacking the source code to the extant programs, I can only offer this output of my own efforts.
To actualize fair use rights with the new IBX, first run 'mirakagi' which will enter the IBX keys into the FairUse4WM blackbox-keys.txt text file. Next, you should use the attached version of FairUse4WM, 1.3Fix-2. This includes an important fix for a video corruption bug, often seen in scenes affording high compression.
If problems occur, please provide the program text. IBX versions after 11.0.6000.6324 are not currently supported.
This version should be capable of interfacing with both Windows Vista and Zune software versions.

It's great to see anonymous hackers, working for free, shredding the best efforts of Microsoft's entire DRM engineering workforce.

Of course, there's an even easier way to get the same music without DRM: just download it from a P2P network. Amazing that Microsoft has set up a world where you get better media for free than you get when you pay for it. Link (Thanks, Abdul!)
