Slashdot Mirror
'First Pirated Ultra HD Blu-Ray Disk' Appears Online (torrentfreak.com)
Has AACS 2.0 encryption used to protect UHD Blu-ray discs been cracked? While the details are scarce, a cracked copy of a UHD Blu-ray disc surfaced on the HD-focused BitTorrent tracker UltraHDclub. TorrentFreak reports: 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!" Those who want to get their hands on a copy of the file have to be patient though. Provided that they have access to the private tracker, it will take a while to download the entire 53.30 GB disk. TorrentFreak reached out to both the uploader of the torrent and an admin at the site hoping to find out more, but thus far we have yet to hear back. From the details provided, the copy appears to be the real deal although not everyone agrees.
This article shows that torrents are another method you stupid idiot.
Why do you need such high quality? At that point it seems like it is all in the mind so you could just repeat positives in your mind to achieve same goal unless you are running a cinema or something?
Slashdot is broken in multiple ways.
The mobile site doesn't display at all in Firefox. The page source shows that content was served, but it's broken enough to not display anything at all. There are features of the desktop interface, like the sliders to change comment thresholds, that simply aren't usable for mobile users.
On the desktop interface, links to older stories or to show all the stories on a previous day do not work at all. Instead, the front page is served up with the most recent stories.
All of these have been broken for several hours, and there are comments about it two stories ago. If there are issues with the server, the right thing is usually to notify users that there's a problem and it's being addressed. Nothing of the sort has been posted. I can't think of any good reason to test out changes on a production site.
If you're reading this, whipslash, this is a really bad experience for your users. Of course, you've made space to cram in more ads on comment pages, so all is well, right? Perhaps you should focus on building real value to this site instead of cramming in more ads to increase revenue in the short term. If you piss off enough users, that revenue will dry up in the longer term.
Well, if such high quality isn't needed then why bother with 4k at all?
UltraHD raison d'etre is that there's people that care about quality... and the quality of a streamed 4k is a far cry from the real deal. No need for cinema sized screens, just a 55" screen and reasonably good eyesight.
Here's something to think about:
Digital Cinema Packages (DCPs) work like this - you own a cinema, you have 1+n screens, meaning 1+n projectors. To screen most releases (very few are released unencrypted), you have to have a DCI-compliant system. Simply put, this means a server with a serial number, and projectors each with a serial number. Each projector has a decryption board inside (no software decryption here, it's all proprietary hardware, look up "enigma board"), with a serial number. Each film is delivered encrypted (either on HDD or downloaded), and a decryption key is delivered via email. The decryption key authorises *that* server to show *that* film via *that* projector from *this* date to *that* date.
The film (data stream) is encrypted until it hits the decryption board inside the projector. So serial numbers and decryption data have to match up all the way through the delivery system until it becomes glowing light. If you take an inspection cover off the projector, it won't do squat until a tech arrives with another key to re-authorise that machine to show films. Of course it's possible to drill and cut a hole in the metal to bypass the "cover open" switch, but that's also trivial to overcome - light-sensitive switch, perhaps, requiring a dark room to defeat. But I digress.
What part of this makes home viewing of films unworkable? IOW it won't be long before your BD player serial number is tied to your monitor/TV serial number, and you get a one-time key when you purchase a movie on disc or download that ties it forever to *that* BD player connected to *that* monitor. So you'll be back to "pointing a camera at the screen" levels of copying.
The system of selling discs to consumers that will only play if a BD player has an authorised matching key (that is common across brands, and is easily accessed in RAM) is not going to last much longer. The system of encryption in DCPs is orders of magnitude more difficult and complex to defeat, but I can see it coming if the copyright lobby gets its way.
They sentenced me to twenty years of boredom
I'm afraid you don't understand encryption at all.
And this *isn't* encryption of data, so much as (attempted) encryption of transit.
Any encryption method, you can openly publish the decryption method and hardware. If you can't, it's no good.
What you *CAN'T* publish are the decryption keys. If you publish these, you are an idiot. CSS, AACS, etc. and pretty much all DRM schemes mis-use transport encryption by giving you the keys too, in some convoluted fashion. They are able to revoke keys, they are able to issue keys to manufacturers, but they are giving decryption keys to you. That's the problem, not the decryption device or decryption method.
Any encryption that cannot survive a known-plaintext attack is useless in the modern era. It's as simple as that. That's not how encryption has worked since the days of the Caesar cipher - even Enigma wasn't really that vulnerable to that because working out the key-settings for a known plaintext was computationally infeasible for the time. Don't believe every line in The Imitation Game ("Heil Hitler! Turns out that's the only German you need to know to break the code!").
So, no, what the problem is is not the encryption. It's the intended use. You give EVERY DEVICE MANUFACTURER a decryption key. Which you can revoke. But which millions of people share.
The reason for this is that otherwise you have to give every viewer a unique decryption key and give them unique copies of their disc, and encrypt data on-the-fly to them (because you can't store 6 billion differently-encrypted copies of the movie). And that just means that one guy has one key, and if he doesn't care about that key being later revoked, he can decrypt his own personal copy and problem solved.
AACS was a little bit more complicated, with all kinds of virtual machines checking state, and things like keys that were generically derivable if you have enough device keys (which means that nobody can trace who actually broke it or blacklist them).
But those are security-by-obscurity and inherent flaws of using encryption as DRM instead of its intended use.
But if you have an encryption scheme where you cannot publish the algorithm, or encrypted known plain-texts, you are very much back in the 60's (e.g. "Modern ciphers such as Advanced Encryption Standard are not currently known to be susceptible to known-plaintext attacks.")
Ok, let's be clear on something. No matters how perfect your protection is, if it's on my screen, I can record it. I can output the signal and the audio on a HD recorder and there's no protection that will protect you from that.
Now, to my point, why the pirate even bother to pirate this encoding? I mean, why would I pirate the BlueRay image full of ads and pointless menu when I can download a perfectly fine and cleaned .AVI with all the Subtitles/Audio integrated?
Or am I missing something?

Found the retard under 25. Just wait until you sit down on your couch, ready to watch your favorite movie, open your streaming provider's library and WHAT THE FUCK!?!?! It's not there anymore. You head to Google and find out that Super Shitty Pictures, Inc. is engaged in a licensing battle with Lame Streaming, Inc. and they've pulled the licensing for all of their titles. Now you can't watch shit because you're too fucking lazy to insert a disk into a player. Enjoy your cloud-based media.While you were doing all that I was watching my Blu-ray movie.
