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.
Ultra HD Blu-ray stores H.265 video on optical discs with capacities of 50, 66, or 100 GB. The original Blu-ray discs stored H.264 video on 25 and 50 GB discs.

The only secret that can be kept is the one that nobody knows exists. That is a lesson of history. And then there are still people who believe that secrets in plain sight can be kept secret.
Reminds me of the crypto-backdoor debate. Does anybody seriously believe that a secret can be kept secret?

But of course. As long you store it on a true write-only device.

In the case where the information cannot be externally verified (e.g. write-only device), torture is completely useless. You tell them anything to make it stop, and they have no way to confirm.

Signetics write only memory chip [repeater-builder.com]. Part 25120.
Some of the supply voltages for the part are interesting, especially VFF = 6.3 VAC.

I used to have these in stock. Many black hole projects have been successfully completed with no remaining evidence present of their existence.
Maybe someone can check for and triangulate some Hawking radiation? Maybe this could locate my old projects?

I need more write-only storage capacity than the 25120 provides, so I use Iomega ZIP drives.

I still have a huge stack of those . . . somewhere. I remember seeing them not long ago shuffling books and computers around.

So, are we getting close to the point where we can start paying for Bluray movies instead of downloading them?

Looks like the pirates will always be able to decrypt these disks. So the movies will always be on the Pirate Bay.
Meanwhile, the cat and mouse game the MafIAA keeps losing continues to hurt people who buy physical disks and want to load them into a digital library for personal convenience.
As long as the movies can be torrented, playing this stupid cat and mouse game hurts no one except the power consumers who are willing to spend huge sums of money on Hollywood content. I guess the producers like it to be easier for these power consumers to steal the content than to spend hoards of money on it.

The MPAA holes are simply trying to hone everyone's cryptanalysis skillz by presenting interesting puzzle challenges to maintain everyone's proficiency.

Can you actually copyright a set of huge prime numbers? Do I need to check some kind of central US-approved registry every time I generate, duplicate, or reuse a key ?
Even Intel could trademark numbers. I'm pretty sure this First-happy SCOTUS wouldn't let **AA-client companies claim ownership of math, as long as no names were mentioned.

Is it the embodiment of a "creative spark"? Or was it generated with no possibility of human crafting, a mere artifact of natural processes? :)

No, they couldn't. That's why they came up with the "Pentium" name instead of using "80586."
