There is a rumour circulating that Windows Media DRM10 has been cracked. We found the following on a blog, but are not sure if the rumour is true or not just yet...
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.
I also found this while searching some groups....
After all I got no response from MSFT... :-(
As far as I survey at this time some popular DRM Protected Video
Providers's contents were cracked...
Many many unlocked video files were distributiong with no payment...
And ...at 17:00(GMT+9:00) anonymous cracker named 'lark' upload source
code of 'DRM crack software'
Software name is "DrmDbg.exe" and "DRM2WMV".
DrmDbg.exe will pick up "KID" and "Seed" from PC's memory when user
playback DRM Protected contents , and make "xxxxx.key" file.
DRM2WMV will unlock ProtectedFile using "xxxxx.key".
Now many many users are downloading it ...access counter is increasing....
It is the worst situation...
WHY MSFT DID NOT PREVENT IT ?
Now I stopped all DRM Server.
I have to save my customer's contents from crackers!!
DRM10 was already cracked whther I set Individualzation Version from '2.2'
I was disappointed at MICROSOFT .
Now we can just sit back and wait for real proof of this.
