A Russian software company by the name of Arusoft may have cracked 4K Ultra HD Blu-Ray DRM. All it requires is a PC with a Blu-Ray drive and a $235 piece of software.

At the beginning of this week a new mysterious company with a new mysterious software popped up, Arusoft with DeUHD. The company claimed that its software would be able to copy Ultra HD Blu-ray discs. In a statement to us, the company even stated that it considered AACS 2.0 to be cracked.

With a license of €200 ($235) there weren't many people who wanted to test and potentially lose their money. Therefore, the company handed out 5 licenses to randomly selected users and the first results are in.

To sum up the results: It works, but they don't appear to have cracked AACS 2.0 itself. Instead, the DeUHD developers appear to have found working keys for specific films.

    On my way over to Pirate Bay right now to look for a cracked copy of Arusoft with DeUHD [thepiratebay.org]

    €200! No way!

    Had they offered it for $29.95 they would have sold millions by now.

    On the other hand if the tacked on speculation is true:

    the DeUHD developers appear to have found working keys for specific films.

    keeping the price high would be the normal thing to do.
    Maybe they stumbled into a cache of known good keys (or brute forcing them).

    It seems that what they are releasing is software that has these keys baked in, rather than one that discovers them automatically:

    According to Arusoft, there will be new movies supported every week and users can request/report new discs to be supported. Decryption of a disc takes about 4-6 hours, Arusoft tells us.

    That almost sounds like Arusoft is finding the keys, and selling keys that work on selective drives, rather than breaking the encryption on end-user drives.

      What do you think all those Russian botnets for for?

        Maybe they could make a cryptocurrency for this: The proof of work is brute-forcing a new Blu-Ray key. :-)

      Or maybe this is a way to avoid extensive pirating, ironically, so they have the software to crack AACS 2.0, but use only "in house", not at the consumer end, so that way if someone uses a cracked version of their software, they may have a way to not give all the keys to it, only to the ones with a valid license.
      It would actually be a good way to "force" people to buy the license, albeit ironic none of the less.
