Windows Media DRM10 Cracked?

So, the word is that a popular internet magazine in Japan has posted information on how to crack the protected files. It appears that you still need a license for the content to start with, that's kind of a big thing. I'm sure there will be more information about this later.

The software has the file names of "DrmDbg.exe" and "DRM2WMV". DrmDbg.exe is supposed to get the KID and the Seed from memory when a DRM-enabled file is being decrypted/played. That spits out a .key file and DRM2WMV is supposed to take that .key and unprotect the WMV. This would leave you with a WMV file that is entirely unprotected and playable in anything that supports WMV playback.

While this may seem like it's great for fair-use and all, many content owners are upset with the matter. Microsoft has not commented on the issue publicly yet. It should also be noted that because of the architecture of WMRM this potential break does not mean that the tools will be valid to use in the future.
