AACS DRM: Cracked Already?

[Specialist]

but I do believe someone will eventually find a vulnerability somewhere in the chain to effectively bypass the protection.

Right.

Then we seem to be in general agreement after all.

That's precisely the point of the cited articles.

They said DVD couldnt be broken, so why cant this. It will be alot harder though to back up the HD-DVDs and blu-ray.

[CrayonEater]

Well, there are no recorders for HD-DVD and Blu-Ray is insanely expensive, so backups are not viable anyway.

Personally, I have no intention on jumping on the HD/BR bandwagon. I've already bought my movies 2, even 3 times over, between tape and DVD formats. It ain't gonna happen again. I'm done.

[painkiller]

CrayonEater hits it right on the noggin.

Many of us, and the public at large, isn't likely to be interested in buying identical movies they've seen/bought on dvds simply because they are now being put on HD-DVD/BD disks.

Way too expensive for those of us working for a living.

C'mon, and how much was a DVD player when they first came out? Or a burner? And how much are they now? Assuming the formats don't actually die, in 10 years, you'll only be able to by Hi Def DVD players, and you'll find 'em at Wal-Mart for $30 (they are backward compatible to DVD y'know). Either they'll be Dual-Format playing, or the Dual-Format discs may have won out. That's the current 'war' - and the only one that matters, if you ask me.

I think they were referring to the cost of replacing your DVD library...

[edong]

Well actually you can, but not in its original format. I've converted MPEG2-HD (720p) material to XVID-HD at the same resolution, but at a size that fits onto a single DVD-R disk. You'll lose some quality, but not resolution, and actually it's hard to tell the difference between the two unless you put them side by side.

May I please know what software you used? Thanks.

[Cornucopia]

Yeah, but if they're backwards compatible (which they would have to be to continue drawing mass customers and gain acceptance) YOU DON'T HAVE TO REPLACE YOUR LIBRARY.

Apparently, this muslix64 character still hasn't clearly told everybody how to get the keys needed to make his program do the job.

Anybody consider the possibility that someone may have talked to this guy (possibly an attorney) and scared him out of going public with this?

Maybe.

But to be honest, I'd figure that anyone providing methods to break DRM, or anything of the sort (real or otherwise), would more or less expect 'cease and desist' notices showing up soon after the posts.

[Coopervid]

No hoax.

Muslix64 really found the codes in memory with WINDVD running. The hunt begins...

Seems like other guys were able to replicate the results on their own. As in the case of CSS an open text decryption key could be intercepted from the software player (memory dump). The foundation seems to be laid out and it appears that guys involved have much better understanding how it all works. This is fascinating. Hats off to Muslix64 and others.

[Baldrick]

Yep, it seems to work. I thought it would take a little longer to crack AACS...

So who will be the first to release HDDVDDecrypter for normal users ?

And has mpaa or the companies behind aacs commented this yet?

[InXess]

At this stage they're probably under strict air silence orders while working frantically on the remedy. As long as there are computer HD software players there's a hope.

[ntscuser]

Never underestimate the video industry's ability to come up with yet another reason for not buying a HD player anytime soon. There's already talk of the encryption system being modified such that every existing player will need to have its software upgraded before it can play the latest titles.

[akrako1]

Once you rip one of these titles, does that get rid of the AACS DRM, so that if we could burn it, whatever player will try and play it won't have to look for a key? If not, then could we reencode the video to wipe out the copy protection?

[InXess]

I think, you would have to hold on with that question for quite some time. Try again in couple months...

I know I have read in the past that both HD-DVD and BluRay were supposed to be loaded with watermarks, so if (when) the encryption was broken and people burned their own back-ups, the players would refuse to play when they detected the watermarks. Of course, you could convert the stream to HD-DIVX and play in a compatible machine with low cost DVD-R and the watermarks become moot. So while I think there will be an acceptable back-up method to blue laser disks, I don't think we will see a comparable version of DVDShrink for HD-DVD or BluRay.

Hmm.... what about home burnt bluray and hddvd discs??? Aren't they supposed to be playable?? I think bluray burners are out and I think hddvd now has them.

Wouldn't there be a way to "preserve" the other watermarks - or replicate them to fake the signals????

[InXess]

AACS is very elaborate with more then one layer of protection. Not that easy. Players can refuse keys. Read the thread at Doom9 also Google and read about AACS.

[VegasBud]

You can also get quite a bit of information straight from the horse's mouth...the AACS Licensing Authority web site. In particular, this page and this page should provide everything you always wanted to know about AACS.

Guys, AACS hasn't been "cracked" at all...
Yes, thanks to the muslix64 we can copy decrypted files to hard disks, but we MUST find the volume unique key first - on our own, in our own memory registers.

What muslix64 did is he shown us the way to use legally available tools (i.e. microsoft's own debugger) to legally find this key stored in the memory of our own computer, and the rest is history...
Yet IMHO it is bigger than DeCSS was (which was stopped with new discs containing new keys if oldest ones here may remember ).
Muslix64's approach allow us to repeat this process indefinitly in the future without any problem with new keys, blacked-out keys etc etc BS from manufacturers.

Yes, he did not gave us AACS Decrypter nor didn't he cracked encryption at all.
but
Yes, he gave us a WAY to use legal decryption routines of a software player to work for US, not THEM, and allow us to copy the HD-DVD's content in a decrypted form on our hard disks.

He didn't broke any laws, yet he show each one of us how to "legally brake the law" on our own (I know, its an oxymoron) - thats the beauty of it

In simpler words: he show us where the key to the cookie jar's lock was hidden by Big Bro - and how to get the cookies with this original key, no crowbars needed

I'm totally confused. So you say he didn't crack it but thanks to his method you can copy and decrypt the content...

Cracking the code means allowing to read what was unreadable before. In that sense he gets the credit (so far) for cracking it. So what did he do? You may call it "open the doors" if you insist. He created a utility to handle the disk content, provided the path to the keys, walked others through their attempt...

Due to the nature of the problem, its complexity (read the thread) it's too early to compose a 1 click thing for you to use, but he did what was deemed close to impossible (at least by some).
Btw. even with the keys DRM circumvention is prohibited so how is this legal...?
You can put it on the market if you want, it's all there...

[RabidDog]

"Anybody consider the possibility that someone may have talked to this guy" heyyy! He's an internet nerdgeek, he doesn't talk to anyone.
But I think hes got a good sense of humour.

dude, its really simple.
If you were to suddenly find a Top Secret documents in your home inside of some program (say PowerDVD ) and you read it - how illegal it can be?
Yes, if you try to sell them to another person, that would be illegal.
Same thing here.
He show us where to look for the key.
He doesn't give us the key (he is not passing the Top Secret ddocument to anyobody).
Got it?

The key to unlock the cookie jar is not really hidden, thanks to sloppy code writers, inadequate x86 architecture, memory management, or whatever is there to blame - it doesn't really matter - the fact is, the key is not difficult to find without any hacking, reverse engineering etc illegal ways.
And whats not prohibited by law is considered LEGAL. The Law doesn't describe legal activities, it describe illegal activities only.
Show me any law saying its illegal to check your own computer's memory dump?
Exactly, you can't.
Unless new amendment to DMCA or other crap will be added, it is still LEGAL to check your computer's processes, their memory use etc etc

[InXess]

...and what do you do with the key you just found?

[DereX888]

...and what do you do with the key you just found?

read the thread again, Sherlock

[InXess]

...and this is how this "it's legal" story ends. Or maybe not... you just plug THE KEY into a... what ??? OK got it, ...commercially available utility (of course, your local BestBuy)) and voila. Sounds like a plan, and this was supposed to be the best encryption industry could ever come up with? If muslix64 ever needed a legal counsel, you get my vote
