• AACS revokes released HD-DVD and Blu-ray keys

  In December 2006, a member of the Doom9’s forum (named Muslix64) released code that would allow a person to copy HD-DVD and later Blu-ray movies. Many claimed Muslix64 did not truly break AACS at that time, because the ‘hack’ only went after the player. On the same forum, in February, a user named Arnezami posted the details and research, but more importantly, the processing key that allowed free copies to be made of any HD-DVD and Blu-ray disk. AACS DRM protection was broken completely.
  
  Shortly after Arnezami’s discovery and the news surrounding it, the AACS-LA, the ones responsible for the DRM used on HD-DVD and Blu-ray released a statement about the reports of the encryption being busted wide open.
  
  “Regarding the reported attacks on 2/13/2007, AACS has confirmed that an additional key (called a “processing key”) has been published on public websites without authorization. This is a variation of the previously reported attack (a compromise of a specific implementation) on one or more players sold by AACS licensees. Although a different key was extracted, this represents no adverse impact on the ability of the AACS ecosystem to address the attack. All technical and legal measures applicable to the previously reported attack will be applicable against this attack as well.” –AACS statement
  
  It would appear that now the action taken was to revoke the published keys, which invalidates the methods used to break the encryption. “In response to attacks against certain PC-based applications for playing HD DVD and Blu-ray movie discs, Advanced Access Content System Licensing Administrator, LLC (“AACS LA”) announces that it has taken action, in cooperation with relevant manufacturers, to expire the encryption keys associated with the specific implementations of AACS-enabled software,” said the AACS LA over the weekend.
