Napster’s WMA DRM Cracked?

Update, 10/07/2006: Those interested in this story might also be interested in the release of FairUse4WM, a Janus DRM evasion tool.

Shortly after Napster-To-Go’s launch about two months ago, word spread
that Napster’s DRM had been “hacked.” Nothing of the sort had happened,
but that didn’t stop Steve Jobs from pushing the rumor forward. Really, someone had posted instructions
on how to take the unencrypted output from the sound card and turn it into
a new wav file.  The spin got so out of control that Napster responded publicly on its website.  

Well, Neowin (via Digital Music News)
reports that the DRM itself may be compromised now.  The details
are sketchy, and the article’s suggestion that the crack is built on
the 2001 Beale Screamer code makes me a little suspicious.  Slyck has a vague article up as well.  Check out coder Cody Brocious’ blog for more details.

    What was “fixed” in WMP to stop Beale Screamer’s code from functioning was the way keys are stored, not the actual algorithm. I can show you some sample license files if you’d like to see that we can get the entire license, since we don’t read from WMP’s cache.

    What’s stopping the release is that we currently don’t know how to generate the license _requests_. If we capture a license over the line, we can decode it, and we have most of the DeDRM code written at this point (I’m finishing up a bit of the WMA demuxer/muxer right now)

    If you’d like to speak further on this, you can contact me via any of the means given at
