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.
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.

Following the release of an Ultra HD (3840×2160 resolution) copy of Smurfs 2 last month, two new Ultra HD Blu-ray films have been released. Ultra HD Blu-ray discs can store 50-100 GB of H.265 encoded content, with 10-bit color depth, high dynamic range, and a wider color gamut. While the AACS 2 encryption protecting these discs may not have been cracked, it seems to be ineffective:
There's quite a buzz among movie pirates who have an eye for high-quality video. After the first Ultra HD Blu-Ray disc leaked last month, two more releases have now followed. While some have rumored that AACS 2 encryption may have been cracked, a bypass is just as likely. And with the leakers themselves staying quiet, the mystery remains.
Up until a few weeks ago, full copies of UHD Blu-Ray Discs were impossible to find on pirate sites. Protected with strong AACS 2 encryption, it has long been one of the last bastions movie pirates had to breach.
While the encryption may still be as strong as before, it's clear that some pirates have found a way through. After the first pirated Ultra HD Blu-Ray Disc leaked early last month, two new ones have appeared in recent days.
Following the historic "Smurfs 2" release, a full UHD copy of "Patriots Day" surfaced online little over a week ago, followed by a similar copy of "Inferno" this past weekend. The latter two were both released by the scene group TERMiNAL and leaked to various torrent sites.
First there was Smurfs 2. Now there are three.
A few months ago, a handful of Ultra HD Blu-ray discs protected by AACS 2.0 DRM were cracked. In October, Russian company Arusoft released a tool called DeUHD that was capable of decrypting dozens more titles. Now a list of 72 AACS 2.0 keys has been leaked, covering titles not previously broken (fixed) by DeUHD:
The keys in question are confirmed to work and allow people to rip UHD Blu-ray discs of movies with freely available software such as MakeMKV. They are also different from the DeUHD list, so there are more people who know how to get them.
The full list of leaked keys includes movies such as Deadpool, Hancock, Passengers, Star Trek: Into Darkness, and The Martian. Some movies have multiple keys, likely as a result of different disc releases.
The leaked keys are also relevant for another reason. Ten years ago, a hacker leaked the AACS cryptographic key "09 F9" online which prompted the MPAA and AACS LA to issue DMCA takedown requests to sites where it surfaced.
This escalated into a censorship debate when Digg started removing articles that referenced the leak, triggering a massive backlash.
Thus fas[sic] the response to the AACS 2.0 leaks has been pretty tame, but it's still early days. A user who posted the leaked keys on MyCe has already removed them due to possible copyright problems, so it's definitely still a touchy subject.
