A hacker has just said he successfully broke the High-Definition Content Access System (AACS) - the standard used to protect HD-DVD and Blue-ray discs. AACS is the next generation digital rights management (DRM) solution, once considered an unbreakable technology.

The hacker claims to be " Muslix64 ", has posted a decoding tool for AACS-protected movies, such as Full Metal Jacket and Van Helsing. The tool is called " BackupHDDVD ", launched a few months after hackers discovered that it was possible to copy frames in the movie using the Windows Screen Print function.

Hackers claim to break the HD-DVD and Blue-ray protection mechanisms images 1 At that time, there were many ideas that copying an entire film through this method was possible. This approach is similar to the method of copying DVD movies using the previous DecSS program.

Content protected by AACS is encrypted using one or more title keys. These keys are generated by a combination of media keys and other elements such as the physical serial number attached to the DVD, and the number of encrypted hash codes according to the title usage.

It is known that AACS standard posted some very well-known brands in entertainment industry such as Disney, Warner Brothers, IBM, Toshiba, Microsoft, and Sony.
