So much for unhackable then.

LOL

These days everything can be cracked.

The DRM is not broken by this. He implemented the decryption algorithm which, as far as I know, is publically available and not a secret. You still can't access the content without knowing the key. The key is (supposed to be) hidden in the hardware (or software). And if a key is compromised it can be revoked (future titles won't play on the device where you got the key from).

So, you can decrypt the DVD if you know the key. This was *always* the case. Everyone knows this. (Everyone with a clue anyway).
In short, this is nothing.

CSS (for DVDs) was different in two ways: 1. The device key couldn't be easily revoked 2. The encryption was weak so that the key could be generated automatically. That's how/why CSS was broken.

AACS suffers from neither of these weaknesses and AACS has not been broken.

Yeah only a matter of time with these things

Until the DRM is totally busted (or abandoned) Hollywood can count me out as a customer. They want their "rights" to come before ours (not that we have any according to them) - I want my "rights" and without that they can't have my money.

So what, we're faulting him because he still needs the input code to begin with? Every decrypted version requires an original encrypted version in order to start the process - you can't copy something where there's no original.

And if the MPAA disables certain players, the companies will be in an uproar - because it's not their faults, nor is it the consumers' who bought those players.

He implemented the decryption algorithm. Why is that a big deal? Because it means that simply by feeding the program one input string, which he has found the way to obtain directly from the discs themselves, he can decrypt them into files that are subsequently saved as unencrypted, and thus no longer deal with AACS at all.

Sounds pretty f'ing broken to me.

Buzzons · 28th Dec 2006, 19:34

Dego -- totally agree, and no doubt there will be an app released by him/others soon that can rip the needed keys etc from your HDDVDs and input them into a database online so others can use them... will be nice

DXR_13KE · 28th Dec 2006, 21:33

nice gift.... lets see if the MPAA will do anything......

Breach · 28th Dec 2006, 22:41

Yeah, that didn't take long did it...

I dont get it, your a peice of immoral sh*t if you download a movie for free, and when you actually buy the content they want to screw you over anyway by barley letting you even watch the movie or play a CD.

You're treated like a criminal whichever way you go, either you are a pirate, or you *might* pirate it seems. So screw em.

I think it is funny that they never seem to notice that every DRM scheme they can come up with is busted flat in a matter of days.

Aankhen · 28th Dec 2006, 22:58

As said earlier... it was only a matter of time. =)

It's half cracked. You can get the files onto you harddisk but until they strip the DRM completely so as you can backup the files to a HDDVD (when the burners arrive) or DVD (?! Dual layer is still 8.5GB) and bung it in some Chinese player that'll play Region 0 stuff, it's not really cracked-per say.

at least they got it into the harddisk with a very small software...... the next logical step is to get rid of the DRM, if there is still some DRM left, or to convert it into a smaller or more usefull file type.

If given time any copy protection will be cracked, now I wonder what this will do to the hd vs bluray fight. One is suddenly less secure.

Same. I want to be able to just pop in a movie and not give a crap about my screen supporting proper copy protection or all that BS. Or, rather, just load up my avi of the film, which is how I deal with my DVDs currently. Until then, their loss.

speedfreek - I think this is a general AACS "crack" which would apply to both formats, the "cracker" in question simply did it to an HD-DVD movie.

I wish it had been BR first, Sony needs another spanking

Tulatin · 29th Dec 2006, 05:16

Why AACS was not cracked? Hello Mr. Tool, i bet you sounded off like this over ArcoDeCSS too. And that got owned. Give it time.

crayfish · 29th Dec 2006, 10:17

Shouldn't the file playing be bigger than 4.02GB?
