p2pnet - rss feed: New AACS crack is for keeps
p2pnet.net news:- “How long before the upgraded security is downgraded?” - p2pnet wondered when Corel Software announced customers would now have to download a new version of its InterVideo WinDVD software if they want to be able to watch their HD DVD or Blu-ray discs on PCs.
Never? That was the implication in a statement from Corel spokeswoman Catherine Hughes. “We have tremendous confidence in the AACS system and our products’ upgraded security,” she declared.
Now, “First much thanks to arnezami for contributing with a xor and sum calculation app and sharing headache,” says Geremia on the Doom9 forums, unravellers of DRM (Digital Restrictions Management) consumer control creations.

I don’t think that getting volumeID without AACS authentication is something very usefull to the most, but i had fun in playing with the drive firmware.
I still have to clear something prior to eventually share, at the moment it’s only a quick patch
It’s yet another way around the copy protection for high definition discs, explains Ars Technica, continuing:
This time, the method involved the Xbox 360’s HD DVD add-on drive to capture the “Volume Unique Keys” as they were being read by the drive itself. Rather than just point out the crack, we’re going to take a closer look at how this crack was accomplished, because one of the hackers involved in the crack says that it’s more or less unstoppable.
The latest attack vector bypasses the encryption performed by the Device Keys—the same keys that were revoked by the WinDVD update—and the so-called “Host Private Key,” which as yet has not been found. This was accomplished by de-soldering the HD DVD drive’s firmware chip, reading its contents, and then patching it. Once that was done, the firmware was soldered back onto the drive.
Despite the technical difficulty of performing this hack, it does offer some advantages in the race to beat AACS copy protection. “They cannot revoke this hack,” said forum member arnezami, who has been at the center of much of the AACS cracking recently. “No matter how many Private Host Keys they revoke we will still be able to get Volume IDs using patched xbox 360 HD DVD drives.”
