AACS cracked for good?

AACS cracked for good? Barely a week after Corel issued an update to WinDVD 8 in an effort to close a security hole opened by AACS hackers, word has spread from hackers that claim the newest update has been cracked as well, and that the newest method is unstoppable.
The new method involves the Xbox 360's HD-DVD add-on drive and its ability to capture the "Volume Unique Keys" as they are read by the drive itself.

According to Arstechnica, "The latest attack vector bypasses the encryption performed by the Device Keys—the same keys that were revoked by the WinDVD update—and the so-called "Host Private Key," which as yet has not been found. This was accomplished by de-soldering the HD DVD drive's firmware chip, reading its contents, and then patching it. Once that was done, the firmware was soldered back onto the drive."

Although performing the hack is technically difficult, "arnezami", a hacker who has been at the center of AACS cracking says its unstoppable. "They cannot revoke this hack...No matter how many Private Host Keys they revoke we will still be able to get Volume IDs using patched xbox 360 HD DVD drives."

"Arnezami" also believes the hack will make future decryption easier: "This hack/technique enables us to figure out how the Volume ID is stored on the disc," arnezami explained. "It's very possible we would figure out [...] how the KCD is stored on the disc. Knowing that and being able to teach a PC drive how to read a KCD will open the door for what I called third-generation decryption."

Although "third generation decryption" is not a reality yet, when the cost of standalone HD-DVD players fall in price, the decryption will become a reality.

And so, with this latest crack, the battle wages on between hackers and content providers.

Ever thought that MS did that on purpose?

Just might win format war. Consumers want something they can backup.

I don't think MS has it that together they spend so much time trowing stuff together and not enough time testing it, I am not saying tis a bad thing it would be funny if its the only Hdvd drive that can be so easily hacked.

I like BR a bit better but Hdvd has a more coherent plan for the future in the end its a coin toss to who wins and theres always a off chance it lands on its side.

The news here is Corel gave it's users an ultimatum ( http://www.afterdawn.com/news/archive/9290.cfm ) and now it's just been thrown back in their faces. The 360 drive has been used for awhile... it didn't take long at all to crack it.

ture but MS being a key player in Hdvd having its own drive hacked to undermine their precious CP is allot more interesting, really corel can not tell what its consumers can do they can try but it wont get far.

its the MPAA (Sony, Buena Vista(disney),Paramount Pictures(viacom), 20th Century Fox, Universal Studios, Warner Bros. (Time Warner). but mostly Sony)that is pushing aacs and hdcp not microsoft. vista has been crippled because of the anti consumer DRM forced upon every piece of hardware that wants a licence to play high definition material!

Schneier: Why Microsoft Sold Out Consumers in Vista
February 13, 2007

Today, the PC industry needs Hollywood more than Hollywood needs the PC. Most consumers rely on traditional consumer electronics devices to view DVDs and TV content, but companies like Microsoft are betting on the converged digital home and desperately want a bigger piece of the media device market. Because of the DMCA, Microsoft has to get permission to build devices compatible with Hollywood's DRMed content. So when Hollywood demanded that Microsoft lard Vista with restrictions to access high-def DVD and digital cable content, the software giant was in a weak bargaining position.

But as Bruce Schneier explains in a recent editorial (via BoingBoing), Vista's DRM may also be a play to turn the tables and turn Microsoft's platform into a distribution channel on which Hollywood relies:

"[W]hile it may have started as a partnership, in the end Microsoft is going to end up locking the movie companies into selling content in its proprietary formats.

"We saw this trick before; Apple pulled it on the recording industry. First iTunes worked in partnership with the major record labels to distribute content, but soon Warner Music's CEO Edgar Bronfman Jr. found that he wasn't able to dictate a pricing model to Steve Jobs. The same thing will happen here; after Vista is firmly entrenched in the marketplace, Sony's Howard Stringer won't be able to dictate pricing or terms to Bill Gates. This is a war for 21st-century movie distribution and, when the dust settles, Hollywood won't know what hit them....

"Microsoft is reaching for a much bigger prize than Apple: not just Hollywood, but also peripheral hardware vendors. Vista's DRM will require driver developers to comply with all kinds of rules and be certified; otherwise, they won't work. And Microsoft talks about expanding this to independent software vendors as well. It's another war for control of the computer market."

Schneier overstates his case a bit when he says Microsoft could have simply refused Hollywood's demands for DRM and Hollywood would have released today's high-def video content for Vista anyway. But he's right that Microsoft would very much like to lock content vendors into a distribution channel that it controls, including for channels like IPTV and digital downloads. And the more Hollywood depends on Microsoft, the more Microsoft may be able to limit competition from other tech companies' platforms and devices.

I think the guys and girls that break these codes should be called the real crack heads :)

well maybe consider a side job with them, I'm sure they would be glad to have you, and maybe pay your kind of rate, hell your one of a fraction of people that agrees with them.

What I stated here does not mean that i agree with them. I was just saying the word crack head should become a positive thing saying that the people that crack these codes are on a good thing. I hope that clears up the misconception.

1519.4.2007 22:30

it most certainly does, my mistake, sorry.
