Blu-ray Protection Bypassed

kdawson posted more than 7 years ago | from the et-tu-Sony dept.

Encryption 407

ReluctantRefactorer writes with an article in the Register reporting that Blu-ray copy-protection technology has been sidestepped by muslix64, the same hacker who bypassed the DRM technology of rival HD DVD discs last month. From the article: "muslix64's work has effectively sparked off a [cat]-and-mouse game between hackers and the entertainment industry, where consumers are likely to face compatibility problems while footing the bill for the entertainment industry's insistence on pushing ultimately flawed DRM technology on an unwilling public." WesleyTech also covers the crack and links the doom9 forum page where BackupBluRayv021 was announced.

What's interesting about all this is that Sony was touting Blu-Ray's wonderful new DRM as unbreakable. I think they gained a lot of support through their claims as well. I'm sure they giggled with glee when HD-DVD's DRM was cracked. I bet they're sobbing into their pillows right now.

MoxFulder (159829) | more than 7 years ago | (#17728416)

Who are the industry people who BELIEVE the crap spouted by Sony/Macrovision/whoever has created the latest DRM scheme??? Considering the terrible track record of DRM of all kinds (basically every scheme ever introduced has been broken), it's amazing that anyone makes business decisions based on it.

Can't they just hire a geek or two to give them the honest odds on how long a DRM scheme will last before being cracked? I could use the job.

Then it's good news for these formats, since it suggests there is more interest. And if I can ignore the DRM aspects of the formats, then I can use them, the same way I can play DVD's on Linux no problem. The formats are much less evil with their DRM fangs removed. The format owners should really pay those who crack their security for the improvement it represents, for making their formats much more accessible for everyone. That's a good thing.

Re:Oh well... (2, Interesting)

Ryan Amos (16972) | more than 7 years ago | (#17728518)

I'm always curious though... DVD never really took off (it was popular, but not in-every-living-room popular) until CSS was cracked and people could copy their own DVDs (or rather buy copied DVD movies for $5 from the kid down the hall.) That was the real death knell for VHS.

But which comes first? The widespread adoption of a format or the ability to easily copy the format's content? I have a feeling it's the latter; which is why strong DRM provides not only a false sense of security, but may actually be the single biggest reason customers choose to shun a format.

CSS was bypassed in 1999 http://en.wikipedia.org/wiki/DeCSS [wikipedia.org] , the DVD released in 1996. Anyway I cant believe this was cracked so fast. Why cant anyone crack [reliably] satellite TV encryption. Now thats something I want to see.

Re:Oh well... (4, Informative)

Tony Hoyle (11698) | more than 7 years ago | (#17728444)

Satellite TV encryption is dynamic. Got the keys? They just got revoked. Worked out the encryption? A download just changed it.

A DVD is a static medium and the players aren't normally connected to a source of data, so they can't update them so fast, and they can't invalidate the encryption without making your existing disks unplayable (=class action lawsuit)... so it's considerably easier to break (and re-break as they issue new disks).

Ever heard of card serving and softCAM?
It completely bypasses the need to write in keys. Even if your keys get revoked while watching, the card client reauthenticates against the stream with new keys realtime.
All you need is someone with legit card and sat box with network connectivity.

No need to clone cards, when you can "clone" the entire authentication module.

This hasn't been "cracked" in any meaningful sense of the word. All they've done is implement a decrypter working from the format specs, and worked out a way to hack decrypted keys out of a software player.

At any point, the player can have its keys revoked and code changed, and we'll be back to square one.

Fuck you twofo (-1, Offtopic)

Anonymous Coward | more than 7 years ago | (#17727910)

Twofo [twofo.co.uk] Is Dying
It is official; Netcraft confirms: Twofo is dying

One more crippling bombshell hit the already beleagured University of Warwick [warwick.ac.uk] filesharing community when ITS confirmed that Twofo total share has dropped yet again, now down to less than a fraction of 1 percent of all file sharing. Coming hot on the heels of a recent Netcraft survey which plainly states that Twofo has lost more share, this news serves to reinforce what we've known all along. Twofo is collapsing in complete disarry, as fittingly exemplified by failing dead last in the recent Student comprehensive leeching test.

You don't need to be one of the Hub Operators to predict Twofo's future. The hand writing is on the toilet wall: Twofo faces a bleak future. In fact there won't be any future at all for Twofo because Twofo is dying. Things are looking very bad for Twofo. As many of us are already aware, Twofo continues to lose users. Fines and disconnections flow like a river of feces [tubgirl.com] .

N00b Campus users are the most endangered of them all, having lost 93% of their total share. The sudden and unpleasant departures of long time Twofo sharers fool_on_the_hill and Twinklefeet only serves to underscore the point more clearly. There can no longer be any doubt: Twofo is dying.

Let's keep to the facts and look at the numbers.

Sources indicate that there are at most 150 users in the hub. How many filelists have been downloaded? Let's see. 719. But 1621 IP addresses have been logged, and 1727 nicks have been sighted connecting to one user over the last term. How many searches are there? 600 searches in 3 hours. The highest sharer on campus, known as "firstchoice", or Andrew.Maddison@warwick.ac.uk in real life, was sharing over 1 TiB, despite working in ITS and not being on the resnet. He's only there so people off campus who think they're too good for bittorrent can continue to abuse the University's internet connection.

Due to troubles at the University of Warwick, lack of internet bandwidth, enforcements of Acceptable Usage Policies, abysmal sharing, retarded leechers, clueless n00bs, and ITS fining and disconnecting users, Twofo has no future. All major student surveys show that Twofo has steadily declined in file share. Twofo is very sick and its long term survival prospects are very dim. If Twofo is to survive at all it will be among p2p hardcore fuckwits, desperate to grab stuff for free off the internet. Nothing short of a miracle could save Twofo from its fate at this point in time. For all practical purposes, Twofo is dead.

Fact: Twofo is dying

suv4x4 (956391) | more than 7 years ago | (#17727918)

Microsoft and Apple are smart. Disk based DRM is doomed since you can't actually upgrade disk drives and disk media that easily, even with encryption programs written dynamically on the disk.

So as disk-based DRM is consistently wrecked, but can't be updated until the next hardware cycle (~7-8 years at least), which alternative becomes obvious?

Software based DRM via network downloads. You can update the DRM-ed player in the next software patch, automated via Internet distribution. Apple is covered with their iTunes store, and Microsoft has been working frantically on heavy DRM in Vista and WMP.

Now you know why.

Re:This won't kill DRM (4, Insightful)

arodland (127775) | more than 7 years ago | (#17728134)

Interesting premise, but think about it. For that to be effective you need to tell people that they can't watch the latest movies or whatever on any sort of player that isn't connected to the internet. If you release anything on HD-DVD or Blu-Ray, it's going to hit this "hole", get converted to some unencumbered format, and away it goes. And "Rocky 9, available today on AppleMovieThing" is locking a lot of people out.

KDR_11k (778916) | more than 7 years ago | (#17728604)

You can fix the DRM with a patch but everything that was released before the patch has already been decrypted and put on bittorrent. Then the new key gets broken and more data gets decrypted and shared, etc. You can't significantly change the algorithm in embedded systems because they probably have a decoder chip (since a full CPU capable of decoding HD video would be pricey) that can run only so many different algorithms.

One can hope..... (4, Insightful)

One can dream that they'll come to there senses. There is nothing more annoying than petty restrictions on the content you buy..

Why shouldn't I be able to watch my dvd/hd movie on my ipod OR computer OR TV. This is getting stupid. The thing is the studios are unified in there stance by the MPAA, maybe consumers should start lobbying or just stop buying..

Does any one remember when the PS2 was anounced, and they said their security method could not be broken? Atleast they don't try and make those types of claims any more.

All this really does is show (yet again) that DRM only hinders honest customers, as any one who WANTS to pirate something, can. The best you can do is force the pirate to do some rather annoyign things to get it all working (think Starforce).

Re:oblig Nelson (0)

Anonymous Coward | more than 7 years ago | (#17728210)

The encryption hasn't been broken.
The cracker was using a perfectly legitimate key to access the data.
He got hold of that key through someone else's laziness.

It's like saying PGP has been cracked because someone left their private key lying around on a floppy disk.

rminsk (831757) | more than 7 years ago | (#17727962)

From the article "The early version of this utility only supports the decryption of Blu-ray discs whose CPS unit key is known." ... "A powerful crypto attack was used to analyze the memory dump obtained from a Blu-ray Disc software player (such as WinDVD or PowerDVD). The crypto attack helped to identify the encryption keys that are needed for decrypting the video files." So it has not been cracked as the keys still need to be found. This just decodes the contents once the keys are found.

Yes it IS a crack (5, Interesting)

ratboy666 (104074) | more than 7 years ago | (#17728538)

The crypto is only as strong as the algorithm, and the method used for key management.

The argument that DRM is "workable" breaks down because the encrypted message is delivered to a party who is expected to BOTH decrypt the message, and NOT know the keys. But the keys had to be used to effect the decryption!

Basically, it makes very little sense.

The only way that DRM can work is if the playback device does not trust its user. Which means that it CANNOT be a general purpose computer.

The next generation of "DRM Operating Systems" cannot support general purpose computing. Pretty much the only way to guarantee that DRM will work is for such a computer to not allow ANY non-DRM compliant software while DRM content is playing.

In other words, while the DRM movie is playing, your spreadsheet won't.

But, since music playback while working is common, we can safely predict that DRM restrictions will be lifted from music. Movies? The next generation may well support "single tasking while movie is playing" mode.

If this is not done (as well as locking out all non-DRM approved drives and kernel extensions), the keyset can be recovered from the player software.

This crack just demonstrates this particular weakness. When I probe a cryptosystem, I look at the algorithm used (are there errors in the implementation? is it a good crypto algorithm? etc.), the keys (key length, is brute force possible or is the key recoverable from a known encyrpted plaintext, was the key produced by someone sane, or an idiot, etc.) and key management (where and how are keys stored and published etc.).

Remember "Spaceballs": the code is: "1", "2", "3", "4".

It is also good to remember that once a single digital copy is "cracked", the work doesn't have to be done for that title again.

It's not cracked, not yet at least (5, Interesting)

FlunkedFlank (737955) | more than 7 years ago | (#17727992)

Again, as with HD-DVD, all that's happened so far is: - he has implemented decryption using the fully public specs - he has recovered some per-disk keys (using a clever technique) by finding them in the memory of software players Neither format should be considered cracked until a standalone software player could play all disks (independent of an online key database) a la DeCSS. That said, major props to him for actually getting done what he got done. The plaintext attack he used to recover the software keys, as described in one of the forum posts, was a nice touch.

Nothing is preventing you from remastering and burning a copy of your original bluray/hddvd. Since you can read out the data, just make another disk and leave the box unchecked which asks "encrypt data for copyright purposes?" and it'll play on any player.
Remastering allows you to cut away annoying fbi warnings, trailers etc unwanted crap from the movies which you own and paid for.

Both formats aren't really cracked, but since it allows creating backups, it does what's neccessary for most people.
Everyone hates plastic disks which cost $30 and are ruined by small scratches.

We've been saying on Slashdot for years. If it can be read, it can be copied. The only possible way to deal with that is to completely lock down all players. But the results of doing that too effectively always seems to end up indirectly reducing consumer demand.

And it's pointless. Most people are happy to pay for DVDs. When you eliminate the people who haven't the technical knowledge to download a movie, those who wouldn't buy it if they couldn't get a free copy, and those who would snub a free DVD quality rip over a paid for HD-DVD quality rip, you're looking at pretty small numbers. Meanwhile, they're putting off a similar number of geeks who are deterred by lack of openness, or region coding, or concerns that the encryption isn't going to be compatible with their TV.

Best part about this is that this time, nobody is going to doubt muslix64. After his first crack was posted people were wringing their hands for weeks wondering if it was legit or a hoax.

The network is now the problem... (4, Funny)

With 20+ GB downloads of HD movies, we're going to need much faster pipes in order to continue to illegally download movies. Verizon should help fund these guys, as it will help sell the 15 Mbit FIOS intetnet option.

The HD-DVD rip of Mission Impossible 3, re-encoded to H.264, had better image quality than any DVD I've seen. 720p, 4.4 GB. For a scurvy pirate, that's more treasure than asked for.

Nah.. been doing that for years (or I was before HD became available in this country - it was the only way to use the expensive HD TVs they'd been pushing us).

Leaving a couple of films on overnight download really is no hassle, unless you're on bandwidth limits (alas, nearly all ISPs here have them now.. they call them 'unlimited' and in the small print you get 'subject to 1gb usage cap'. My own ISP only has a cap during business hours though).

something useful? (1, Interesting)

Maybe muslix can fix the HDDVD and bluray players so they don't downgrade component outputs.

Not hacked or cracked - "bypassed" (0, Offtopic)

Zantetsuken (935350) | more than 7 years ago | (#17728292)

I was testing /.'s FireHose system earlier today and saw another submission on this - except that one made it more clear as to what was done to get around the DRM content protection. Basically, its the same thing you can do with a DVD, VCD, or any video file - xvid, h264, etc encoding in avi, ogm, or mastroska containers - that is, make frame-by-frame screen-captures of the video and stitch the resulting images together for a new video file without DRM. To my knowledge, yes, this method does result in a pretty much exact copy of the video, except that because it's basically taking those million frames in the video and saving them as raster images and putting in a fast, 25-30fps slide-show...

or at least thats how I understand how it was done anyway - btw, I think it had said it was something like the Intervideo WinDVD player used, though there are other players which I am sure can do this (from the other article I mentioned)...

Unfixable (1)

MBCook (132727) | more than 7 years ago | (#17728348)

This problem that's been used to crack both BR and HD is basically unfixable the way things are isn't it? It's an interesting read on the forum how he did it (page 2, I think). The problem is that the key is in plaintext in memory. But it HAS TO BE doesn't it? You couldn't use it if it was still encrypted, and so you'll have to decode it and put it in memory at some point. The only fix to this would be what a poster on that forum mentioned wouldn't it? You rely on a piece of silicon you control to do all the decoding and such, which would require a BluRay player card or something. You'd have to basically get rid of software players.

Almost right. Dedicated silicon would be one way.

Besides that, the only OTHER option would be for the entire system to be "secure" through things like so called "Trusted Computing" [wikipedia.org] . In parituclar check out the section on Memory Curtaining [wikipedia.org] .

You'll notice that in this case, "Trusted Computing" has nothing to do with the User trusting the platform, but rather with the Media Companies Trusting the system to look after their interests above that of the users.

Re:Unfixable (2, Informative)

Tony Hoyle (11698) | more than 7 years ago | (#17728630)

There are ways of not doing so... for example putting bits of the key in different places in the memory map. Putting crucial bits of the key in kernel memory where userspace can't read it... deliberately obfuscating parts of the key (eg. xor the 10th byte with some value, thus invalidating it unless you know that it's been done).

TPM will hold the key in unreadable (to unauthorised applications) static memory. Once that gets on your PC you've got to crack TPM first.. and that's going to set you back *at least* half an hour :p

He didn't crack Blu Ray or HD DVD (3, Informative)

melted (227442) | more than 7 years ago | (#17728376)

What he did crack is one software based player. There's now a difference. Key holders will now revoke the keys for that particular player, so it won't play newer movies anymore. There's no crack yet that would defeat the entire protection scheme.

Re:He didn't crack Blu Ray or HD DVD (1)

Crazy Man on Fire (153457) | more than 7 years ago | (#17728668)

Only problem is that (as far as I can tell) he hasn't disclosed which software player he used. How do they know which keys to revoke? Even if they do revoke the keys, the player will fall victim to the same attack again next time 'round. Later. Rinse. Repeat.

Well, duh (-1, Redundant)

Pluvius (734915) | more than 7 years ago | (#17728384)

BD uses the exact same form of DRM that HD-DVD uses, so of course he succeeded in circumventing it. Unfortunately for HD-DVD, though, BD already has other forms of DRM as part of its standard. They just haven't been widely implemented yet.

People can pick locks too... (1)

Afecks (899057) | more than 7 years ago | (#17728400)

You can buy lock picking books and tools easily. Yet you don't see people leaving their homes and cars unlocked because they are suddenly made worthless. Locks are good, so is DRM, when it works properly. It needs to be open, non-intrusive (for the owner) and allow fair use. Unfortunately it seems that the **AA is more interested in forcing consumers to re-purchase every album and movie they own each time a new technology comes along. Anyone who thinks that DRM is to stop pirates is uninformed. It's to stop you from taking all those DVDs, converting them to XviD and storing them on cheap mass storage. It's more profitable to slowly kill off DVDs with Bluray and force everyone to buy both Godfather movies again (Godfather III, you're nothing to me now).

The only difference between some fair use and illegal copying is intent. Not a system in the world can discern that.

If it can't allow fair use while blocking unlawful reproduction then it must allow both.

This is very good news. (1)

lordvalrole (886029) | more than 7 years ago | (#17728410)

This gives the movie industry no where to run. There was the fear that when the HDDVDs had a work around that the movie industry would go bluray. Now this gives the movie industry very little room to do much of anything at the moment. They just don't get it. There will always be someone smarter than the people who are smart enough to reverse engineer things. They always think they are one step ahead but in reality they aren't. I would like to thank muslix64 for all his hard work.

Re:This is very good news. (1)

lordvalrole (886029) | more than 7 years ago | (#17728452)

sorry what I meant to say is...there is always someone smarter than the people who actually make the encryption. They can always reverse engineer and find a work around.

The drawback people have spotted here (5, Interesting)

goldcd (587052) | more than 7 years ago | (#17728450)

is that you can't just run the program to decrypt all your Blu-Ray(or HD-DVD) disks, you need to locate the key and use that to get the unprotected data.
This sounds like a right pain in the arse. I'm used to buying DVDs willy-nilly and just shoving films onto servers, PSPs, iPods, XBMC etc as the mood takes me. It always works, I just press a couple of buttons and away I go.
Reading these stories have made me think - I'm now even less likely to buy a HD disk than I am a standard DVD. I buy a HD disk in the shop and I've now got to worry, can I get the key for this disk? will it be for the right region? will it be the right version (you can be sure once a disk is cracked they'll shove new keys on all future pressings).
I don't think I can be arsed with all this really.. much easier just to download un-encrypted and know it'll work on everything I own, forever. FFS I'd pay more for the pirate version than the legit one given the chance.
My next prediction is the appearance of a site that'll serve keys. You put your HD disk in your machine, run a util that gets a hash from it, searches online and decrypts the disk automatically.

that all this is is minidisk versus digital compact cassette all over again. how many minidisk or DCC players do you own

Re:it bears repeating (1)

Tony Hoyle (11698) | more than 7 years ago | (#17728690)

Hmm... 3 minidisk players, no DCC players (or did you mean DAT? same answer but probably for different reasons).

The problem is ask 10 slashdotters and you'll get 10 answers to this.. so I don't know what you were fishing for...
