The companies behind an encryption system for high-definition DVDs are looking into a hacker’s claim that he has cracked the code protecting the new discs from piracy, a spokesman for one of the companies said Thursday.
A hacker known as Muslix64 posted on the Internet details of how he unlocked the encryption, known as the Advanced Access Content System, which prevents high-definition discs from illegal copying by restricting which devices can play them.
The AACS system was developed by companies including Walt Disney, Intel, Microsoft, Toshiba and Sony to protect high-definition formats, including Toshiba’s HD DVD and Sony’s Blu-ray.
Muslix64 posted a video and decryption codes showing how to copy several films, including Warner Bros’ Full Metal Jacket and Universal Studios’ Van Helsing, on a popular hacker Internet blog and a video-sharing site.
The hacker also promised to post more source code on Tuesday that will allow users to copy a wider range of titles.
