[UPDATE 03/26/08 - Exercising its "Right to Reply" I have the following to share from Macrovision Corp, the company who currently owns the rights to BD+ technology:

“Macrovision does not comment on specific techniques or procedures that may directly impact the BD+ security technology.  BD+ is a security response system designed to react to security attacks, not prevent them entirely.  As part of this system, updated BD+ security code is continuously developed so that BD+ customers obtain ongoing value from the use of this technology.”

SlySoft, the makers of AnyDVD HD, have released an updated version of the copy-protection removal tool which allows Blu-ray owners to back up their discs.

AnyDVD HD now with BD+ support

Film studios that have switched to Blu-ray may have crowed a little too early because the much-praised BD+ copy protection is an ad absurdum affair now, too. With today's release of version 6.4.0.0 of AnyDVD HD it is now also possible to make backup security copies of Blu-ray discs protected with BD+.

BD+ is the DRM protocol used to protect Blu-ray discs.  It's a very sophisticated scheme that makes use of a small virtual machine environment to enforce compliance.  BD+ was considered much harder to crack than the encryption used on HD DVD discs (which SlySoft cracked last year).  In fact, faith in BD+ was so strong that Richard Doherty of Envisioneering Group was quoted in July of last year as saying:

BD+, unlike AACS which suffered a partial hack last year, won't likely be breached for 10 years.

Can Blu-ray be tightened up following this crack?  Sure.  Even SlySoft admits that a future tweak to BD+ could put an end to this crack, although the company is optimistic that a a crack could be found.

Peer van Heuen, head of High-Definition technologies at SlySoft adds: "Admittedly, we are not really so fast with this because actually we had intended to publish this release already in December as promised.  However, it was decided for strategic reasons to wait a bit for the outcome of the "format war" between HD DVD and Blu-ray. On top of that, we first wanted to see our assumptions confirmed about the in the meantime released BD+ titles regarding the BD+ Virtual Machine. We are rather proud to have brought back to earth the highly-praised and previously "unbreakable" BD+. However, we must also admit that the Blu-ray titles released up to now have not fully exploited the possibilities of BD+. Future releases will undoubtedly have a modified and more polished BD+ protection, but we are well prepared for this and await the coming developments rather relaxed". Van Heuen adds jokingly: "The worst-case scenario then is our boss locks us up with only bread and water in the company dungeon for three months until we are successful again".

In other news, the other day I picked up an LG GGW-H20L Super Multi Blu-ray writer / HD-ROM reader drive.

  • "BD+ won't be breached for 10 years"

    Nothing like a challenge to get people moving. I wonder how those studios who went with Sony instead of Toshiba because of their "better" security feel now.

    • ::snicker::

      You gotta love Big Media and their obsession w/copy protection, don't you?

      Just like Bush Rethuglicans and their insistence that "inconvenience + crushing of civil liberties = 'safety'"....

  • Couldn't happen to a better standard.

    By Better I mean absolutely ridiculous in the contempt it has for consumers. I only hope that Sony et all enjoy the hundreds of millions they continue to throw down the drain developing the superspectangularwonderouslystupendingous DRM crap, driving their player prices up.

    Eventually, they will learn that people want cheap players who's PRIMARY role is to just play the movie stupid.

    I am heartened to see this crack, and the movie studios salivating over the above mentioned DRM will start to see the futility of it all. They aren't ready yet though, the NEXT version of DRM will do the trick, just you wait and see.

    • I couldn't agree more... Blu-Ray is bad!

      I guess I'm one of the lucky ones. Not in that I didn't buy into HD DVD, but I didn't buy into either format. I would have preferred that HD DVD won, but the money was thrown at Blu-Ray so there was no chance. (Consumers didn't pick Blu-Ray, the execs did.)

      I kinda wonder if the studios would have jumped on Blu-Ray so quickly if this crack had been released in December like it should have been. Makes you wonder doesn't it...

  • Did the crack influence your decision?

    Inquiring minds want to know.

    • Not mine.

      Not mine. I won't be getting Blu-Ray until my local movie rental stops putting DVDs on the shelves. Even then, I'll probably be doing rentals online anyways.

    • I'll wait until they lose the battle for good.

      Throw in the towel, admit defeat, get back to an attitude that the customer means something (AKA Amazon MP3), they stop the $200 overhead for useless DRM software, and players that just work are sold for $75-$100.

      It is amazing that they still operate under the assumption that consumers NEED them, they don't need us.

      I would have been OK if HD-DVD reader/writer was included in a computer I bought (would not pay a premium) because it is fully usable in Linux (no links, not wanting to be deleted) without the required monitoring connection, but the technology doesn't thrill me, my upconvert DVD player works great.

      It is a nice to have at the very best.

    • No ...

      ... my components "dealer" offered me a really good deal.

      Can't say I'm not happy though!

  • RE: SlySoft cracks Blu-ray BD encryption

    pretty sure I've seen software out there that has already cracked BD+...same people that make DVD-Decrypter think...I'm probably wrong but I was pretty sure this had already happened about 9 months ago..

  • Secondary anti-consumer offering

    I share the delight that SlySoft gives the disc owner the ability to put the content we purchased on our hard drives and congratulate them on their work.

    However the studios still make it more expensive than necessary by using older MPEG2 compression rather than either of the other supported codecs. Typical movie files alone come in around 25G. Of course using a newer codec may mean that the movie would fit comfortably on a DVD9 at full 1080p. That would have made the whole HD-DVD/BluRay war moot, and we wouldn?t want to have missed that would we?

    "we had intended to publish this release already in December as promised. However, it was decided for strategic reasons to wait"
    I would not be surprised if the contacted Sony and
    said "what does it worth to you if we wait a little
    until the major studios decide and then come out with the
    crack?"
    Sony is not stupid b/c they know about the studios obsession with DRM
    I'm sure that was a major part in their decision.

    Its great but Blu-ray will not be here 10 years from now.
    Because electronic and software companies want to hook you and then move on.

  • RE: SlySoft cracks Blu-ray BD encryption

    I am glad that this will end the lock out for backups, but it will never be enough to stop the spiral of security vs hack that a few pirates or thieves bring upon us, these sociopaths cause us all to pay a premium price that would be otherwise unnecessary.

  • RE: SlySoft cracks Blu-ray BD encryption

    If any division of the entertainment industry deserves this, it's the film industry. I know of no other sector that shows such utter contemp for its customers.

    They release a DVD, then the 2 disc special, the the 2 disc special directors cut, then the 3 disc, extended "as the director intended it" edition. Then they'll release the 3 movie "trilogy" box set, 6 months before they release a 4th movie in the "trilogy" to make the boxset worthless.

    Then they have the nerve to say it's the customer ripping them off when it all goes pear shaped. Good on yer Slysoft, kick em where it hurts and kick em often.

  • So, they cracked it...

    ...but did they (sony) ever bother to fix the situations I've heard told here on ZDNet where the players block you from playing certain discs you purchased simply because you bothered to buy the highest quality hardware? It apparently thinks that because you did so, you're ultimate goal is trying to pirate the content? (gasp) God forbid we have that ridiculously high expectation of actually being able to USE the expensive technology we rightfully paid for.

    Now THAT's DRM doing wonders for the industry.

    They will never learn as long as people keep handing them money by buying their over monitored, over oppressive, you're guilty until proven innocent, refuse. Let's all say it now folks: "Bah'ah" Yup, that's a good sheep. It's spring now so your wallet shearing is coming soon.

    Many states, if I'm not mistaken, allow for one legal backup of your media, as long as it remains in your possession. I'm surprised nobody has class actioned the MPAA for blocking their legal rights yet.

    So I'm glad they broke it. Not that it matters for me since I don't plan on buying HD until this DRM junk goes away anyways.

  • Anything That Can Be Programmed

    ...can be programmed around. That's been the case from the beginning with computers. Somewhere I still have instructions on how to break the copy protection on VisiCalc, a copy of CopyCat (a program designed to duplicate copy-protected disks on the Radio Shack TRS-80 Model III), copies of CopyIIPC (same kind of thing as CopyCat, but for PCs), and a bunch of other cracks, hacks and patches I've accumulated over the years.
    Copy protection, DRM, encryption, you name it; it's new rehashes of the same old failed idea that software or something software-generated can be locked up with software. The hackers and crackers will work around it eventually, and everybody else will be inconvenienced (and some folks will use the cracks, hacks and patches just to be able to use the legit product they've paid for).
    A quality product for an enticing price is the best defense against illegal copying. If that doesn't provide sufficient profit incentive, either something's wrong with the product or something's wrong with the business plan. And fixing the plan doesn't involve suing dead people, 12-year-old girls and people who don't have the product and wouldn't know how to use it it they did.
    That's my 2c. So there.

    • Esepcially if you have all the keys.

      2048Bit PGP is still uncracked (last I checked) just because it uses a public/private system where only the recipient has the decryption key.

      DRM, on the other hand, has no hope no matter how clever or strong the encryption is because between the medium and the playback device all the keys are there and it all has to be fully unencrypted at some stage for the content to be at all usable. All that has to be worked out after that is the encryption algorithm and a little analysis of the Java Bytecode should reveal all.

      Really, having part of it in software has made it easier to tease out the algorithms because it's a lot simpler to dissasemble bytecode and have it converted to human readable instructions than it is to dig around the inside of a player with probes and interpret the output signals.

      In short: it doesn't matter how strong the encryption is unless at least on of the keys is hidden, everyone can access the algorithms used in PGP and it's still monumentally difficult to break because keys are hidden, but even that wouldn't matter with DRM because hiding any of the keys would render media unplayable.

      The entire concept of DRM is bunk.

  • Bound to have happened

    Since when has any antipiracy method not been cracked? It always happens, there has yet to be a antipiracy method that has not been cracked afaik. Personally I think we'd be just as well going back to the honor system because these antipiracy measures don't really provide any extra benefit to anyone.

  • RE: SlySoft cracks Blu-ray BD encryption

    My father always said that locks were made to keep the honest people out. I think the same applies to DRM. Making it harder for Joe User to (ILLEGALLY) copy his software or movie for his neighbor keeps a lot of people out. That being said, Joe Cracker will be able to make copies.

    A note to the self-riteous/indignant: Don't think anyone believes that the bulk of CD / DVD copies are for legal purposes.
