Backup Your Blu-ray DVDs with BackupBluray

Well, maybe not just yet, as the BackupBluray utility is just in Alpha stage, it will only decrypt Blu-ray discs whose CPS unit key known, but one user, at least, has confirmed he has successfully ripped an entire movie, or has posted that he has, I didn’t see any proof, but I haven’t finished reading the whole thread yet. Muslix64, the same guy who created BackupHDDVD to allow people to backup their HD DVD’s, has once again developed a program to copy the supposedly unbreakable DRM, this time on Blu-ray DVD’s, BackupBluray is it’s name, and while it can only copy discs whose key’s are known, he said full decryption will be added soon.

A new utility has just been released in a very early Alpha stage, aptly dubbed “BackupBluray”. This BackupBluray tool is designed to help backup Blu-ray (BD-ROM) movies. The early version of this utility only supports the decryption of Blu-ray discs whose CPS unit key is known. Support for decryption via a Volume Unique key will most likely be added in the near future as development continues. At this point, a stable version of the tool is not yet available for mass distribution. The initial tool has already proven successful though, as there has already been one confirmed report of a successful Blu-ray Disc backup. If the BackupHDDVD tool history is any indication as to where BackupBluray will end up, we can expect to see the source code released to the public along with a SourceForge.net project opened.

So, the supposedly unbreakable DRM’s used on both of the new standards have been bypassed by the same guy, they are not technically being cracked, what he is doing is grabbing the encryption keys from a disc and decrypting the movies. He has been using a “powerful crypto attack” to analyze a memory dump from a Blu-ray disc. The movie companies spent a lot of money on these DRM’s, well, I should probably say, consumers are going to spend a lot of money on these discs because of the money it cost them to develop these standards.

After spending a bunch of money on my current collection of DVD’s, I’ll be dammed if I will upgrade to either of these standards and replace my entire collection again. Devices are already available that will show your current DVD’s in high definition, and I am sure there will be more solutions available, I will buy one of those players and keep purchasing the regular DVD’s, if none of us buy these players and discs, then the movie companies will be stuck with them, and I can tell them where they can stick them.

BackupHDDVD 1.0 Released

Muslix has released his tool to allow you to copy HDDVD movies, it is called BackupHDDVD, he didn’t actually crack the DRM, like I said here, but, because the players are insecure, he can extract the keys to allow him to copy the movies using his program.

The attack I describe in “Affirmation 4″, is not here yet, but its coming. So I give MPAA and AACSLA a head start. Start to think what you can do about that.

To totally block this attack, they need to put different keys on every disk! Now, they only have different keys for different movies. I don’t know about the manufacturing process of the disk. This solution may not be possible.

The best they can do, is doing shorter manufacturing run of a particular movie, so it would be difficult to get your hand on every “pressing” of a movie.

When they design AACS, they assume people will look for the device keys. I don’t care about device keys. I do care about volume key. Having the device keys mean that you have to re-implements all the complex crypto and do the full AACS process.
I leave all this dirty job to the player and recover only the volume key.

There is 3 important things in cryptography:

1-Private key protection
2-Private key protection
3-Private key protection

Did I break AACS? I don’t know. What do you think? Source: BackupHDDVD, a tool to decrypt AACS protected movies

He posted download links here, with the hash to verify.
