SkillZ wrote to mention an article at the IBT site discussing a fix to the security breech of the HD DVD and Blu-ray media formats. "Makers of software for playing the discs on computers will offer patches containing new keys and closing the hole that allowed observant hackers to discover ways to strip high-def DVDs of their protection. On Monday, the group that developed the Advanced Access Content System said it had worked with device makers to deactivate those keys and refresh them with a new set."

IT: AACS Cracked Again 306 comments
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."

For example. I have a DVD player that made by a no-nane Chinese brand, bought for 30UKP (around 60USD). It's not region free but can be unlocked by a magic button press combination on the remote. Instructions for said inputting magic combination were given to me at the shop when I bought it. It plays anything I throw at it. Even half arsed DVD rips that I failed to burn correctly.
On the other hand, my father has an expensive Sony DVD player. It's region locked, doesn't upscale for his HDTV and takes great offence if anything is slightly out of spec on the DVD disc.
Now to bring this vaguely back on topic, from a consumer point of view, which is better? I suspect those without any knowledge of region encoding (or in the case of HD-DVD, DRM) most would simply conclude the more expensive player is 'broken' and opt for the cheaper region free/DRMless player.
Fair enough, at the moment with HD-DVD they do not have a choice. Bottom line is, while the average consumer might not care about their 'digital rights' they dam well care about their shiny new disks working in their shiny new HD-DVD player. This has the same beneficial effect to my mind, the end of DRM. The movie industry pisses off the average consumer at their peril.

Used to be, industry considered the ridicolous size of CDs protection enough -- 700MB or thereabout would take forever to download, and be completely cost-prohibitive to store on a hard-disc anyway.
Then lossy compression came, and gave results that are acceptable to 99% of the listeners for 1/8th the size or thereabouts, which means we're at less than 100MB for a CD.
Then bandwith grew -- 28.8 gave way to 56.6 gave way to 128kbps and then on to broadband -- initially 700kbps or thereabouts, today typically 2-4Mbps in the USA, 5 - 25 mbps in Norway.
Even at the lowest speed offered by my ISP (6 Mbps symetrical), downloading a 100MB album takes less than a minute and a half, which is trivial.
Then movies. DVDs -- it was argued, hold 5-10GB of data, so are completely impractical to pirate. The same story repeated. Compression came. You can download a 1-2GB version of a 10GB DVD with a quality good enough for 99% of the viewers -- there's much better codecs out there than the ones used on DVD.
1GB of data is like 15 minutes at full throttle even today (still with the LOWEST speed available from Lyse), even the full uncompressed DVD at 10GB or so would be downloaded in about 2 hours, which is still practical.
Now it's argued that whatever NextGen disc at 50GB or thereabouts will not be pirated because the size makes it impractical.
Give me a break. 99% of the people who listen to music find well-encoded 192kbps mp3 to be "good enough", the same people will very likely find a 1-5GB recompressed version of a blueray original "good enough" too. And they'll be able to download and store the original trivially a few years in the future anyway.

It's really important that everyone understand that AACS copy protection cannot be brute forced. They're using AES for the actual encryption - if someone wrote a program that could crack that directly the news would be a lot more significant than "DVD copy protection hacked".
Given that AES won't be cracked, any attack on AACS copy protection must be a key recovery attack. Luckily, key recovery attacks aren't that hard when you get a key with every player you buy. But... the fact that cracking AES is hard means that reading HD-DVD/BluRay disks may become completely impossible when players are no longer available.
Hacking something together to read a Beta tape is possible. Annoying. It might cost tens of thousands of dollars to build. But it's possible - it's just analog magnetic patterns on a tape. Reading an HD-DVD without a HD-DVD player won't be possible. That'll be a serious issue for historians in the future, if people don't leave enough pirated DVD-R's around with the unencrypted content on them.

Unfortunately, high prices and the lack of working copies/backups makes the legal offerings un-attractive for many. I have kids. I have cases that used to contain working DVD's. Lack of backups is a problem. I'm moving to a Linux Media Center PC. This new format is incompatible. A media server is a much better solution for most families than a shelf of out of order/broken/lost DVD's. The inability to make a backup/working copy is a crime. DVD's in the home make as much sense as a CD player tethered to your iPod instead of a hard drive. Kids don't take CD cases to school anymore. They know they get stolen, lost, broken, etc. They rip the CD's at home and load them on their iPod with the originals safely stored away.
SONY Dreamworks doesn't get it. I bought Open Season. It has some copy protection on it besides CSS. Guess which film won't be in the Media Center? Guess which brand I'm not buying in the future? Chances are that title won't be watched much simply because it's inconvienent. It's like copy protection on CD's. The kids have iPods. They rip their CD's. CD's that don't work are remembered. That artist and label get a critical review on their next release. Kids instead of buying CD's they can't use, look elsewhere such as P-P and sneakernet. Copy protection (Defective product) sends buying consumers elsewhere.
I remember what CD's and DVD's can't be ripped and who put them out.
Since I did buy Open Season, I will be looking for an already ripped copy or a solution to rip it myself. So far, the rip it myself solutions seem to be mostly commercial offerings.

DRM is not about stopping serious copying groups... The warez scene will still rip this media and distribute it online, and dodgy street corner vendors will always have copies for sale. These people simply wouldn't watch these movies if they couldnt get free copies.
DRM is about preventing legitimate users (who are willing to pay) from doing things like format shifting. The media companies want those people who buy movies anyway, to buy additional copies to play on their ipods, portable players etc, rather than converting their existing media.
If I buy a CD, I can produce a copy for the car, i can rip it to my ipod, i can rip it onto my laptop. This is all covered by fair use in some countries. The RIAA/MPAA wants to take away our fair use rights so wring more money out of people...
If they openly admitted the purpose of DRM was to remove people's fair use rights and get more money out of legitimate buyers, there would be public outcry and they'd be taken to court. So instead, they try to claim it's to prevent organised piracy.
The constant cracking of their protection schemes just proves that it doesn't stop piracy _AT ALL_.. If preventing piracy was the true reason for DRM, they would have abandoned DRM years ago, as it's costing them a lot of money to develop while doing nothing to stop piracy.

Also, let me point out, I haven't read the code in its' entirety yet, but if I understand correctly, the volume key crack should actually be immune to key revokation, based on my understanding of AACS, key revokation should only effect device ids and once a method of extracting a volume ID is known, the revokation mechanism just no longer matters.
Of course, I'd also like to point out what others have already said. If a program exists that can read the data and decrypt it, then it's 100% obvious that the program can be reverse engineered. This is not an opinion, it's fact. I have on many occassions bypasses hardware dongles, FlexLM, trial periods, etc...
bypassing hardware dongles requires that you reverse engineer the driver to the dongle, this is just plain easy, all you need to do is find a disassembler that can handle the format, or if it's a kernel mode driver, then you just use a kernel mode debugger... not an issue. when you locate where the driver is being attached to from the program itself, then you just emulate the hooks. Even the most advanced dongles are easy to hack this way.
FlexLM... well... come on... this one is just so easy it's not worth talking about
Trial Periods... they can vary... depends on how obscure people want to make the code. But for the most part, they're not that hard. For example, I found a function reference in a DLL on PcAnyware (don't remember the version) called "TimeBomb()" which returned a boolean value. Not really that hard huh?
As for HD-DVD and BluRay... if all else fails, run the player (really really slow) through an emulator like QEmu and trap all IDE calls. Log the previous 1000 instructions run before the hook and then log until the first picture comes up. Then just review the log and read the source code left in the log. Hardest part is making it pretty enough to read... but if it means that much to you... well no problem.
- So... in brief... copyprotection is just a joke... laugh at it!

If I had the choice of hardware that would do what I told it or hardware that would obey the whims of the MPAA/RIAA, I'd choose the open hardware. Given the choice of software that does what I tell it to or software that doesn't, the choice is obvious. If there is no choice, I write my own software.
The most insulting thing about the rootkit incident, as well as many such events since, is the notion that just because I'm using my computer to play content owned by someone else they somehow they own my hardware. That's simply not the case.
Here's what I want to know. They're sending a patch to the software that plays the discs, right? It's already too late to change what's on the actual discs because too many are already in the wild, so to speak. What if I just don't update my software/firmware? Or better yet, what if I write my own?

Indeed.
Look at Infernal Affairs - the original from which "The Departed" was remade - done in Hong Kong it had a budget of roughly 5M USD at the time. The Departed had a budget of roughly $90M and that does not take into account advertising. That's almost a 20:1 ratio and many people argue that "Infernal Affairs" is still the better movie.
Look at "Il Mare (Siworae)" - the original from which the recent Keanu Reeves/Sandra Bullock "The Lake House" was remade - a budget of under 2M USD versus roughly $40M for the remake and if IMDB's ratings are anything to go by, the original was better. Again a 20:1 ratio.
Furthermore, South Korea regularly turns out top caliber movies and yet the most expensive film they've produced, The Host, [wikipedia.org] had a budget of $10M. Most South Korean productions are well under half of that, often closer to $2M, and their quality easily surpasses most of what Hollywood does.
South Korea is one of the few markets in the world where local productions regularly beat out Hollywood for ticket sales (in part because of screen quotas, but that changed recently due to the US State Department doing the MAFIAA's biding and it still didn't put a dent in local cinema). These movies focus on story rather than flash, so there are less special effects. But otherwise the movies look just as good as anything from Hollywood - professionally lit, professional wardrobe, make-up, cinematography, and of course the most important part -- great story telling.
While production costs are cheaper in South Korea and Hong Kong than they are in Hollywood, they are not necessarily less than for a lot of "run aways" where Hollywood outsources various parts of the production to cheaper parts of the world.
So, yes it is easily possible to outdo Hollywood and even produce 'blockbuster quality' (if quality is the right term) movies for far far less than Hollywood does right now.

What they have done is analogous to re-keying a lock that is susceptible to being picked -- it's only a matter of time before it is picked again. Lather, rinse, repeat. And how long before a hardware player is cracked? If I had one I'd bust into it to see what kind of flash it has. It probably has an on-board JTAG or other programming port to dump the memory like most consumer devices which are mass produced and then flashed assembly style, making obtaining the key quite easy. When the players come down in price I fully expect them to be cracked on a daily basis.

Also given the nature of this sort of thing, I also figure pretty soon there will be increased interest in hacking a stand alone HD or BD player... as the price comes down I'm sure the allure of forcing revocation of a series of hardware players will attract attention.

The benefit of all these cracks isn't to allow people to copy the movies. That ability was never in doubt -- people will always be able to do that. They'll be able to do that regardless of what the content monopolies do, short of just deciding that they won't release movies anymore (which is fine; there's enough of a demand for entertainment that other people will do it -- there's nothing special about making movies that a lot of people can't do, it just takes a lot of money).
Holding onto a crack until AACS is ubiquitous wouldn't do anything. The ultimate failure of AACS isn't, and never was, in doubt -- all DRM is flawed, and it will eventually be broken.
The question is whether it's possible to convince both the studios/content-creators, and consumers, of the utter futility of DRM in the first place, so they'll stop trying to do it, and stop wasting everyone's time. DRM is nothing but a broken window: it's millions of man-hours and probably billions of dollars of resources diverted from other, more productive, tasks, both to create it and break it. That's the real cost of DRM.
So if by releasing cracks for AACS every time they update it, as quickly as possible, it demonstrates to the studios that they're engaging in a war against a guerrilla enemy that they can't possibly defeat, regardless of how much money they spend, perhaps they'll throw in the towel sooner rather than later. It may be a slim chance, but given that Apple has started to see the light, there's some hope.
That's the real benefit of these cracks. Compared to the economic and social cost of the wasted effort, the ability of people to pirate a few movies pales in comparison.

In practical terms, for a specific encryption algorythm, it might, for example, be estimated that it would take 1 man on 1 PC up to 8000 years of continual effort to break a particular encryption algorithm.
However, get 2 men on 2 PCs working together, it'll take up to 4000 years to break it.
4 men on 4 PCs will take about 2000 years to break it.
etc.
Based on that assumption, I give your encryption keys 1 year at the most.

No, seriously, we did... Really.
So, unless some miscreant goes out and breaks something, yes, it is fixed.
Hackers of the world: It ain't broke, so please don't be taking it apart to find out why. Please! The fact that you can't watch movies you paid for on the equipment you own is a design feature. Please don't meddle with it, it will only make more work for us.

And havering a no return policy will not cut when people say I just payed for this and it does not work, I have to pay for the internet just to see a movie, It does not work with dial up internet, I can't get high speed internet so this HD-DVD / Blue-Ray player is useless to me, and so on, I tried to do a firmware update and it failed and now the player does not work at all,
The player says I need a tv with HDMI / HDCP 1.3 and I just got a new HD tv not that long ago, What is a firmware update? The people at walmart likely will have no clue about that one.

It's much more efficient, and higher quality, to intercept the data before it gets decoded, and it's even more time-efficient to have the keys to decode the stream directly and write it back to disc at the speed limit of the player. Luckily, we have people in the hacker community with nothing better to do than play cat-and-mouse with the DRM houses.
*for the record I own neither an HD-DVD player nor a HTPC, though I am building the latter to store my 200+ DVDs I currently have in a hardware jukebox for more convenient viewing)
