MS DRM Version 2 - Cracked
As the title says: Microsoft Digital Rights Management Version 2 has been cracked. The Register has the story, including a link to a downloadable zip file which contains source code, explanation and a small DOS utility. Grab it while you can. You can also read the explanation directly here, and you can also find it with Google.
This is just like the deCSS hack - a good piece of work exposing a flawed implementation of a rights management scheme.
.wma files on Linux - the decoder still requires the MS dll to get the keys out for you.
However, at the moment two little differences are apparent:
1. This doesn't allow you to decode
2. The author has remained anonymous! No DMCA prosecutions here, assuming she has covered her tracks properly.
