New hack simplifies HD video copying
A hacker claims to have discovered a cryptographic key that can be used to circumvent copy restrictions on HD DVD and Blu-ray movies.
The key, which was published Sunday on the Doom9.org discussion forum, is a further step toward undermining the next-generation AACS (Advanced Access Content System) encryption system used to copy-protect high-definition media.
The hacker, going by the name of Arnezami, said he discovered the key by examining what was happening in his computer's memory while it processed an HD-DVD video.
A spokeswoman for the group that sets the AACS specification, called the AACS Licensing Administrator, said Arnezami's claims were being investigated but declined to provide further comment.
