Digg losing control of their site (HD-DVD encryption keys were posted)
InfoWorld ^ | May 1, 2007 | Kevin Railsback

Posted on 05/01/2007 8:58:23 PM PDT by HAL9000

Excerpt -

The folks at Digg.com have let the social news genie out of the bottle, and now they can't control it. Since the HD-DVD encryption code was discovered and published, readers at Digg have been repeatedly submitting stories with the 16 digit hex code in the titles and bodies. Just as quickly as these posts crawl up the Digg charts, admins seem to be deleting them.

Just search Google for 09 F9 and you'll find the key. Will AACS send a Cease and Desist to InfoWorld because I posted the text "09 F9"? If so, we might as well give up on this whole Internet thing right here and now.

Can a simple, short string of numbers and letters (the full key) really be copyrighted? And is Digg.com receiving a proper takedown notice for each case, or are they taking things into their own hands and deleting posts willy-nilly?

The same sort of thing happened when the DeCSS code came out - I even have a t-shirt with the code printed on it. This just goes to show how useless the DMCA is, and how information cannot be controlled, and that DRM will never truly work.

Okay there’s four pecks in a bushel and two half-acres in an acre. But I don’t know what they’re talking about above.

Did you know that you could get into really big trouble if you post the code beginning with 09 F9 11 02 on your website ? It is very likely that a takedown notice will be send to the owner of the website as soon as the RIAA, the AACS or some of their lawyers find your website. You might be wondering why they are making such a big deal about this code that continues to be 9D 74 E3 5B D8 41 56 C5 which only some users might identify as the code to rule them all.. aka the processing key that unlocks the content of every HD-DVD available up to this point.

Did you know that this was the processing key that ends with 63 56 88 C0 ? I did not until I read an article where the AACS sent some takedown notices to websites owners who mentioned the key. So, what is actually happening now is that this key will be reproduced on thousands of websites who report about this takedown notices, it will be available in caches, in forum entries and in many other places including custom created T-Shirts, Mugs and Mousepads. It seems that the takedown notice somehow backfired on the AACS, don’t you think ?

You said — “uh, what?”

They’re talking about “cracking” the new HD DVD, which is supposed to make it so that you cannot copy those DVDs. However, this “crack” makes it possible and they’re trying to “put the genie back into the bottle” — which will never happen...

While the Band is Wagoning

So I really know little to nothing about encryption policy and I have never even seen an HD-DVD to date but I feel that I might as well join the rest of the internet in posting this.

Apparently with this code 09 F9 11 02 9D 74 E3... (if you want the full code, it’s not hard to find) you can do something with the encryption on HD-DVDs. I want to be very clear in the fact that I have no idea what to do with this number and have no desire to learn.

The problem comes with the MPAA and other groups trying to stop the HEX code from getting out and distributed. Can they actually trademark/copyright/patent/whatever a hex number sequence?

Digg has been removing posts about this all day apparently and it seems to have boiled over and people are not happy. Just check out digg.com and you should easily find article postings about this topic and pretty much every comment section, no matter the article, now mentions the code.

Again, I have no information on how to use the code or even what the code means - I only know what it is and would have never given it a second thought had they never tried to protect the information so aggressively.

I’m just tired of businesses - for profit businesses (RIAA, MPAA, etc) acting like they are law enforcement agencies. They are not and they should follow the proper legal channels just like anyone else. Got a copyright infringement complaint against someone? Present the proof in court and see what happens - don’t send fake “comply or die” messages.

You mean 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 ?

:-)

Just doing an experiment....

[for the rest of y’all, looking at that series of numbers above, you wouldn’t think something like that is as serious as Osama bin Ladin, would you???]

Too bad it wasn’t Blue-Ray that got cracked..they
are much more insidious and anti fair-use than
HD-DVD.

The New HD-DVD/Blu-Ray Hack: What It Might Mean For Us

Picture_7_8 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

That's the so-called "Processing Key" that unlocks the heart of every HD-DVD disk to date. Happy Valentine's day, AACS.

AACS, a DRM scheme used to encrypt data on HD-DVD and Blu-Ray disks, would appear to be cracked wide open by that short string of hexadecimal codes, as previously, only disk-specific Volume Keys were compromised. The new hack is the work of Arnezami, a hacker posting at the doom9 forums, fast becoming the front line in the war on DRM.

"The AACS is investigating the claims right regarding of the hack," said AACS spokesporson Jacqueline Price. "It is going to take a appropriate action if it can be verified."

Price said she could not disclose what their investigation might entail, or what "appropriate action" might be.

“We’ve just learned of this claim today and are checking into it,” said Andy Parsons, chair of the Blu-ray Disc Association and senior V.P. of product development at Pioneer Electronics, in an email.

The new crack follows that from earlier this year, when a hacker by the name of muslix64 broke the AACS system as it applied to each movie. While the earlier hack led to 100 HD-DVD titles and a small number of Blu-Ray movies being decrypted one-by-one, the so-called "processing keys" covers everything so far made.:

"Most of the time I spend studying the AACS papers," Arnezami said in his forum post revealing the successful assault on the next-gen DRM system. "... what I wanted to do is "record" all changes in this part of memory during startup of the movie. Hopefully I would catch something insteresting. ... I now had the feeling I had something. And I did. ... Nothing was hacked, cracked or even reverse engineered btw: I only had to watch the "show" in my own memory. No debugger was used, no binaries changed."

It's not yet clear what it means for the consumer's ability to copy movies, or, for that matter, that of mass-market piracy operations. The short form is that the user still needs a disk's volume ID to deploy the processing key and break the AACS encryption — but getting the ID is surprisingly easy.

Arnezami found that they are not even random, but often obvious to the point of foolishness: one movie's Volume ID turns out to be it's own name and the date it was released. There isn't yet an automatic system, however, that will copy any disk, in the manner of DeCSS-based DVD copying systems.

Even so, the new method completely compromises HD-DVD in principle, as it relies on AACS alone to encrypt data, even if there are other parts of the puzzle that are yet to fit together. Blu-Ray has two more levels of protection: ROM-MARK (a per factory watermark, which might revoke mass production rights from a factory but not, it seems individuals) and BD+, another encyption system, which hasn't actually been used yet on sold disks (but which soon will be), meaning that its own status seems less obviously compromised.

How might the companies respond? The processing key can now be changed for future disks. However, the flaws inherent in the system make it appear easy to discover the replacement: the method of attack itself will be hard to offset without causing knock-on effects. For example, revoking player keys (in advance of obfuscating the keys in memory in future revisions of the system) would render current players unable to view future movies. Revoking the volume and processing keys that have been hacked would mean that all movies to date would not run on new players.

Publishers could randomly generate Volume IDs in future releases (as they are still needed for the current hack to work), which would make them harder to brute-force. That said, it's claimed that the "specific structure" of the Volume ID in memory makes it feasible to brute-force randomized ones anyway.

Following are links to the current discussion at the doom9 forums, in which Arnezami and other provide regular updates on their progress. We don't offer any warantee that the software implementations so far produced won't blow up your computer or get you thrown in jail and whipped with wet towels by MPAA lawyers:

Yep, I would make it so that *everyone* makes it a signature line on every communication that they do, e-mail, postings, boards, whatever....

Digg? Oh - you mean the site for snarky young communists in training. The commentary section is rich - a bunch of pedantic teenagers slagging each other off.

I suppose this means that it's good that I haven't blown money on a BluRay or HD-DVD player. Cracking the encryption system means the manufacturers will have to find a new approach. The existing players won't be able to play the disks created with a different encryption technique...at least not with the original firmware installed. It might be possible for a firmware upgrade to rescue some players...if that capability is provided. A $1,000 paper weight is no laughing matter.

Too bad it wasn’t Blue-Ray

Give it time.

Someone, somewhere, is diligently seeking an answer to that riddle as we speak.
