from the "Blu"-ray-and-Smurfs dept.

An alleged copy of an Ultra HD Blu-Ray disc has appeared online, leading to speculation that AACS 2.0 has been cracked:

While there is no shortage of pirated films on the Internet, Ultra-high-definition content is often hard to find. Not only are the file sizes enormous, but the protection is better than that deployed to regular content. UHD Blu-Ray Discs, for example, are protected with AACS 2.0 encryption which was long believed to unbreakable.

A few hours ago, however, this claim was put in doubt. Out of nowhere, a cracked copy of a UHD Blu-Ray Disc surfaced on the HD-focused BitTorrent tracker UltraHDclub. The torrent in question is a copy of the Smurfs 2 film and is tagged "The Smurfs 2 (2013) 2160p UHD Blu-ray HEVC Atmos 7.1-THRONE." This suggests that AACS 2.0 may have been "cracked" although there are no further technical details provided at this point. UltraHDclub is proud of the release, though, and boasts of having the "First Ultra HD Blu-ray Disc in the NET!"

[...] If the encryption has indeed been broken it will be bad news for AACS, the decryption licensing outfit that controls it. The company, founded by a group of movie studios and technology partners including Warner Bros, Disney, Microsoft and Intel, has put a lot of effort into making the technology secure.

"Atmos" refers to Dolby Atmos (see PDF list).

    Another possibility is that somebody got access to a pre-release master of the bluray that had no encryption to begin with.
    Soylent just ran an article a couple of days ago about somebody who got into an unsecured system that contained a netflix show.

    Will just have to see how many other UHBDs show up.

    Would a master have the Blu-ray file structure and 50-100 GB size of UHD Blu-ray?

    There is a possibility that there could be a key revocation linked to this, which would be as good of a confirmation as anything.

      > Would a master have the Blu-ray file structure and 50-100 GB size of UHD Blu-ray?

      Yes. Encryption has to be the absolute last step of the process because DRM prevents any further modifications. So if you get access to one generation before that final step it won't be encrypted.
