HD, Blueray Processing Key Found
Looks like someone has found the master key to unlock ALL HD DVD and Blueray titles, this will allow you to unlock, decrypt and backup every title that is out, and one assumes the ones coming out for a bit, at least until they change the key or come up with some other way to encrypt them using this or another DRM.
There were just two major problems left: how do you detect the Processing Key and if it?s not in memory how do you find it at all? Well since I now knew how things worked I knew the Processing Key had to be combined with a C-value to produce the Media Key. The problem was there are 513 C-values in the MKB! Searching the memory (several megabytes) for a Processing Key and assuming just one C-value would take minutes (if not hours depending on the size of the dump). So doing them all would take very long. And that while I didn’t even know for sure there was a Processing Key in memory to begin with. I made a proggy that did this but using my favorite “corrupt” memdump I didn’t find any Processing Key in the first megabyte (not for any C-value). It didn’t look good.
There was a trickle of titles hitting the torrents, now you can expect a huge flood, and cries of foul from the movie companies.
