Reports are coming in fast and furious that the AACS DRM system used by both HD-DVD and Blu-ray players has been cracked by someone with the codename muslix64. I had reported earlier on a possible brute-force print-screen method of cracking HD-DVD.
This new method seems to rely on a compromised HD-DVD player whereby muslix64 was first able to access the unique decryption keys for particular HD-DVDs. Then using those keys and his java-based BackupHDDVD program, muslix64 was able to implement the AACS decryption protocol as outlined at aacsla.com (the official AACS website) and play it back using standard HD-DVD play-back software (in this case PowerDVD 6.5 HD-DVD).
Muslix64 says the tool works on his XBOX 360 external HD DVD player, but that the software would not be limited to just one specific player.
It is unlikely that this will become the HD-DVD/Blue-ray equivalent of DeCSS, however, because it does not provide a universal method of decrypting HD-DVD/Blu-ray disks. Nonetheless, even if this is only usable by the most dedicated of hackers, once a decrypted HD-DVD/Blu-ray title is out on the wild and wooly Internet, it would be freely copied by the P2P community. As the recording industry knows too well, it only takes one decrypted copy for the file to spread around the Internet like wildfire.
Whatever its future, DVD Jon is smiling somewhere.
