A Doom9 member, ATARI Vampire, has posted on the Doom9 forums that he has found the WinDVD 8 sub device key in memory. This is the latest of several weaknesses exposed in the Advanced Access Content System (AACS) copy protection that is used to protect the contents of both commercial HD DVD and Blu-ray Disc titles.
Using the WinDVD 8 Device Key, it is now possible to decrypt any movie playable by WinDVD 8 by using it. The new discovery by ATARI Vampire is based on previous work done by muslix64 and arnezami. Muslix64 found a way to retrieve the Title Keys and released BackupHDDVD, and later, BackupBluray. Arnezami extracted the processing key of a software player.
WinDVD 8 was also shown to be vulnerable to a simpler "Print Screen" attack several months ago, but that vulnerability was quickly (apparently) patched. SlySoft has also brought a software solution for decrypting HD DVD movies for the average user, releasing AnyDVD HD some weeks back.
