AACS Cracked Again 306

EmTeedee sends us to a blog post for a summary of the latest results in cracking AACS, from the Doom9 forums (as the earlier cracks have been) — after the DVD Security Group said it had patched the previous flaws. From the DLTV blog: "This time the target was the Xbox 360 HD DVD add on. Geremia on Doom9 forums has started a thread on how he has obtained the Volume ID without AACS authentication. With the aid of others like Arnezami they have managed to patch the Xbox 360 HD DVD add on... It appears that XT5 has released [an] application that allows the Volume ID to be read without the need to rewrite the firmware. This would mean that anyone could simply plug in the HD DVD drive and obtain the Volume ID from any HD DVD without the hassle of flashing it."

    Someone really needs to fire whomever the MPAA uses for deciding on security for these things. Haven't they heard the golden rule of computer security? "Security by obscurity is no security" and that's all they are doing is trying to hide a key. Find the key... no security. Sheesh....

    I'd try to crack the stuff from a number of different fronts, but keep quiet until I've cracked a few. With several cracks and exploits found, I'd be able to start working on higher level cracks, due to understanding the system.

    Then I'd start releasing the cracks, starting with some of the simpler ones, only releasing another when they patch the exploit I released, resulting in an ongoing sense of futility as every time they fix the holes, I point out another.

    Best exploit I think? Stealing or cracking the key to every code created for the discs. That way they'd have to throw the whole system out in order to achieve 'security' again. No current players would work. While a massive beowolf cluster cracking the whole thing would be neat and worthy of the NSA, I think that's unlikely. More possible but still pretty much 'mission impossible' would be a physical theft. If only the DVD Security Group protected those keys like government officials protect our information*...

    hm...

    *Yes, I'm still a bit irked about having my info stolen at least three times

    I was reading parent post and did a double-take, as what I got of it was:

    "I can't wait until they realize that it's not worth it, and just stop concerning themselves with creating good movies, and instead focus full-time on copy-protecting their media."
    ...which in a way seemed to make total sense, there is a perverse part of myself that thinks that this is almost where we are headed.

    DRM or not, the current 1 freaking minute booting time for HD DVD players (dunno about BluRay) is enough to put me off the damn things.

    No more movies! Ever! We quit!

    The movie industry.


    That really wouldn't be the worst thing in the world. There's a huge demand for movies, but they're expensive to make and the current movie industry sucks up most of the available investment dollars. There's no "secret sauce" involved in making a movie; it's just very, very expensive, and the people with enough cash to bankroll a film would rather go with an established, sure bet, rather than taking a chance on someone or something new.

    If the current players just decided to pack up and go home, the new industry that would rise up in its place would doubtless be a lot more creative -- at least in the short term -- and we'd probably see a lot of new material out of it. In time, it would probably stagnate, too, because that's the way of things.

    The main problem with the current situation is that the dinosaur companies have bought protection for their business models from the government, and essentially have propped themselves up. There's nothing bad with companies getting big, but there's also nothing that says they have a "right" to stay in business, either. Failing business models deserve to die, and the companies that rely on them deserve to die, too; when they don't, you're stopping what ought to be a natural economic progression.

    I know what your saying and I agree with it, but having the legal right to make a copy doesn't mean that they don't have the right to try and stop you. I just wish that they would realize that most people like to buy stuff, I know I like to buy DVDs it makes me feel warm and fuzzy to be like "Hey I bought the whole (insert show or movie) series". But the truth is that its too expensive to buy everything I would like to. Production costs at this point of the DVD release have usually been covered(excluding making the menu releasing extra content and having a commentary that I never listen to except on south park dvds) the packaging and DVD for a season of south park is about 50 dollars canadian when it comes out. It probably cost them 5 dollars to make(my guess and some might say it was high some might say it was low theres 3 dvds in there with graphic lables and casing and maybe shipping not sure if the store pays for that or not) so lets say the store like HMV or Best Buy makes about 10 dollars off of the sale. Thats 35 dollar profit for the manufacture. Lets say you pay Matt Stone and Trey Parker to do their commentaries for it, they probably get a % of sales. so if you sell 100,000 dvds of one season you get 3.5 million dollars, say matt and trey take 10% each the studio is left with 2.8 million.
    if you reduced the cost so that a box set costs 40 dollars using the same numbers you end up with 2 million. This gives you less profit right? Well if people are more willing to buy a dvd at 40 dollars and you get 150 000 dvd sales you end up with a final profit of 3.75 3 million dollars. Your making more money. I know nothing and I'm bored so don't take me too cereal. I know people will still pirate dvds but people will always pirate dvds, you won't stop them. Use the money that your putting into research to reduce the cost of the product and sell it and I bet you will have less people pirating or at least buying a legit copy after pirating or before making a backup. I know I would.

    I find it bad form that I've paid 8*45+20(best of volume was cheaper) for my south park dvd collection. Thats almost 400 dollars. come to think of it that seems insane, and thats not my only collection. Most people can't aford that and I can see why they pirate or make backups. Would you want to go out and spend that again if your DVD got wrecked by a scratch?

    Here's an outlandish idea:

    Microsoft and Toshiba screwed this up on purpose to undermine the AACS. Defective by Design, sure, but this is probably one of the few times that it ROCKS.

    When they decide that they can't prevent theft, they might just decide that they can instead use the increased distribution to their benefit via increased ads inside each movie.

    Might even make sence for them to produce two versions of the movies:
    1. Free Electronically distributed , with ads maybe non skipable commercials between chapters
    2. Not free, no ads + DRM


    of course pirates would still try and rip the add free discs, and or remove the ads from the free version, but it might remove the incentive for many people to pirate the non free disks. I mean, most still watch tv with ads, instead of tivo-ing it and skipping the commercials or downloading it without commercials, right?

    They don't care if it gets cracked. They only care how difficult it is to keep up with the crack-patch cycle. Their goal is to make it difficult or risky for John Q. Everyman to copy movies and music.

    They have to know that all their security measures will be broken. They can win by attrition.

    As inconvenient as it is, the real reason for DVD security like AACS isn't for the consumer. Sorry, you're not that important.

    When people invest millions of dollars in developing a standard like HD-DVD, Blu-Ray, or whatever comes along next (UV-DVD?), they need assurances that they will get their money back. They don't make money off of the sale of DVDs, but rather off of DVD hardware. So companies that manufacture DVDs can't just build players, they have to buy little AACS chips directly and exclusively from the standard's creator, and pay them a fee.

    They don't /really/ care if you break the encryption, because no DVD-player manufacturer could ever go out and use the cracks to avoid paying Sony / Toshiba/NEC. AACS has done its job, in that sense.

    I'm glad AACS was cracked. I don't particularly like the idea that I have to rely on a physical copy of something I allegedly only own the rights to "watch" anyways.

    Well said.

    The conventional wisdom is that Hollywood sucks and anything would be better. I think what gets lost is that making a decent movie is tremendously difficult. It requires a lot of highly skilled and experienced people. Making a great movie takes that same stuff, only more, plus a lot of luck.

    Hollywood movies, for all their flaws, usually get most of the . . . technical stuff right. That's a huge plus.

    Beyond that "the Hollywood machine" does a vast amount of work vetting material. I'm sure some profound art is lost in this process, but it really does keep the self-indulgent pap to a minimum.

    The indie approach is everyone and their dog makes a movie, and the cream rises to the top. The Hollywood system aims to never shoot the crud [wikipedia.org], and just shoot the 10% that might be worthwhile. I think that this creates a (comparatively high) floor on the quality of Hollywood movies, but does lower the ceiling on just how good they can be a bit.

    That's why "all the really good ideas come from outsiders".
