AACS hacked to expose Volume ID: WinDVD patch irrelevant
The DRM "protecting" HD DVD and Blu-ray Disc films -- AACS -- continues to unravel at the seams. In parallel efforts, hackers in both the Xboxhacker and Doom9 forums have exposed the "Volume ID" for discs played on XBOX 360 HD DVD drives. Any inserted disc will play without first authenticating with AACS, even those with Volume IDs which have already been revoked by the AACS LA due to previous hacking efforts. Add the exposed processing keys and you can decrypt and backup your discs for playback on any device of your choosing. So yeah, it looks like last week's WinDVD update has been quickly and definitively made useless just as we expected it would be. Well, for XBOX 360 HD DVD drive owners anyway but you can see where this is heading, right? Now go ahead AACS LA, revoke the Toshiba-built XBOX 360 HD DVD player... we double-dog dare ya.
AACS cracked again: WinDVD key found
AACS has already been compromised in at least two widely known ways, after DRM hackers posted on the Doom9 forums methods to retrieve and utilize volume, and later, processing keys to copy every Blu-ray and HD DVD movie released so far. Today a third method has appeared, as poster ATARI Vampire reports they were able to find the "sub device key" of the WinDVD 8 playback software. That key identifies the player and allows it to decode AACS protected titles. You might remember the software was also the victim of a simple "print screen" attack several months ago that was quickly patched. The method used to find it was based on arnezami's previous approach of watching memory dumps and finding it through a "bottom up" approach. Coming on the heels of the cracks already widely available, this doesn't really affect the current state of easily copied high def movies, but could make disabling the vulnerable player from playing future releases, finding the hole and preventing it from being hacked again, that much more difficult.[Via Slashdot]
Hackers discover HD DVD and Blu-ray "processing key" -- all HD titles now exposed
Those cooky kids over at the Doom9 forums hate themselves some DRM. Not more than two months after discovering a means to extract the HD DVD and Blu-ray Disc "volume keys" to decrypt AACS DRM on individual films, we're now getting word that DRM hacker arnezami has found the "processing key" used to decrypt the DRM on all HD DVD and Blu-ray Disc films. Let's break this down for what it is: instead of needing individual keys for each and every high-definition film -- of which there are many -- the processing key can be used to unlock, decrypt, and backup every HD DVD and Blu-ray Disc film released so far. As arnezami points out, "nothing was actually hacked, cracked or even reverse engineered." All he had to do was keep an eye on his memory, watch what changed, and voila... the processing key appeared. So kick back and watch the trickle of HD titles hitting the torrents quickly turn into a flood (at ~20GB a pop, that's not an exaggeration) when the BackupHDDVD and BackupBluray utilities (or AnyDVD HD) are updated to reflect the new hack find.
