New AACS cracks cannot be revoked, says hacker
Only a few days after Corel issued a WinDVD update to close the hole opened by AACS hackers, the folks at the Doom9 forums sent word that they have found yet another way around the copy protection for high definition discs. 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."
