All Blu-ray Disc and HD DVD Encryption Defeated by One Key

The first breakthrough came when a hacker named "Muslix64" circumvented both HD DVD copy protection and Blu-ray copy protection, resulting in the release of pirated copies on the Internet. On Sunday, another Doom9 forum poster named "arnezami" discovered how the Processing Key could be used for decryption on both HD DVD and Blu-ray discs (Previously every HD movie needed its own unique key in order to be decrypted). Arnezami used only an Xbox 360 HD DVD player, the bundled King Kong movie and his computer to find the key. Other Doom9 forum contributors proved that both HD DVD and Blu-ray Disc movies could be decrypted using the Processing Key found from King Kong.

Arnezami unlocked the secrets to HD DVD and Blu-ray Disc encryption without the use of any hacked software or hardware: "Most of the time I spend studying the AACS papers. A good understanding of how things worked have helped me greatly in knowing what to find in the first place (and how to recognize something)." Arnezami isn't revealing which software player he used to expose the key information for fear that the Advanced Access Content System Licensing Administrator would crackdown on the software developer. What he did want to say, however, is that he made his discovery simply by watching the data as it passed through his system.

While all you hackers are out there finding "processing keys" or “volume keys”, you’re destroying the very fabric of the system that creates these technologies, artwork and music for you to appreciate.

Why would a musician make a cd that cost thousands of dollars to make, to have everyone steel their work for free. Get real. Arnezami and Muslix64, your just destroying entertainment for everyone.

There is a reason for copyrighting. Violating copyright is stealing someone else’s work, and money. Anyone who contributes to this is no hero, and you are NO hero.

uh this keys is only good for discs with this particular manufacturing key. future discs can have a different key. just all discs checked so far use this one key on both format.
So while better then the volume key that people have been using for a month, it is just as stoppable. Altho the bad software players need to have their devices keys revoked first to prevent new keys from being found in seconds.

it makes me smile until I realise that the added cost of producing copy protection that is useless but expensive is passed on to buyers like me. Almost makes me want to pirate, EVERYTHING.

Thank God he cracked both, or else we'd have retards posting..

"HAHAH, HD-DVD IS BETTER. BLU-RAY SUCKS"

OR

"BLU-RAY > HD-DVD! FORMAT WINNER!!!"

You do know that I hate all you fanboy tards, right? F--kin losers.

If he did hack only one format.. .everyone would preffer the hacked one, lol

appart from all the noobs who make up the majority :P

wooot!

Now if only these stupid media corporations would give us the ability to freely navigate our dvd instead of forcing us to watch the stupid warnings/previews, which is why i may never purchase a movie, ever..

CrisCr0ss - Well said. Every time I'm forced to sit through 6 different MPAA warnings and get locked into mandatory previews on something I just purchased, it makes me want to rip the disk and post it across the globe. Man, the whole industry sucks for one reason or another, but that especially chaps me.

Good. Films will always be cracked by the professional pirates and all normal consumers get is the ever increasing loss of control over their purchases.

They say on release that these things will never be cracked, and proved wrong once again that it is cracked very shortly after release :p

The player that was used, will be exposed soon enough, but I have a good idea as to which one it might be !

For real. All the research and development was just a waist of money.

I'm not saying that they should have it in an unencrypted format on the disc...i believe that something in the DMCA in the US makes punishment more severe if the user knowingly decrypts the copy protection as oppose to just violating the licensing agreement. In this case they should have just used good old CSS like in DVDs because someone is bound to break the encryption anyway.

Another point I'd like to make is other then Blu-Ray's larger size capacity over HD-DVD, the format has also boasted stronger copy protection which now can not be used as an argument for the formats superiority over HD-DVD.

BD+ and ROM-MARK are not turned on yet, just AACS.

If anything, it will force the BD studios to use them now, leaving Universal and any HD DVD studios subject to piracy.

I did not know that these encryption features were not "turned on yet" as you put it. What makes you think they will be any different?

Well if they turn on ROM-Mark, no burnt disks will play because the player checks for the mark and its not present unless your using an authorized blu-ray press thing.

AND that will be cracked too. It would be in the same vein as modding PS2 or X-Boxs.

Nothing to help the distribution of HD-DVD or BluRay movies. With masive broadband download pipe, P2P will have a filed day with that.

That is what the NIKE network is for. All you need is a storage device capable of holding a movie and a good pair of feet. This of course requires friends, but those seem to be easy to come by when someone has something of value to offer in a social bonding experience.

However, by the time you read this, it is very likely that the MPAA will have lobbied Congress to outlaw all removable storage options (provided that range from >= to 25gigs).

In all seriousness, it is likely that when 10mb to 100mb pipes become available you will easily be able to download HD content. So your last assertion would be correct. When the technology is available, P2P will have a field day.

I actually believe it would be better for the MPAA and RIAA if their products did not have any content protection of them. These strategies only hinder the legitimate user and encourage a black market to grow.

Actually, the proper term is "sneakernet." No trademark issues with that term, which has actually been used for quite a while. Wiki on sneakernet: sneakernet

For a whole lot of people out there (if you call bidirectional 10+ Mbps by fiber massive), that requirement is already satisfied.

Already there and common in a number of countries.

Arnezami used only an Xbox 360 HD DVD player, the bundled King King movie and his computer to find the key.

Shouldn't that be King Kong?
