HD DVD copy protection circumvented?

28 December 2006 1:03 by Jari Ketola | 51 comments

According to reports the AACS (Advanced Access Content System) DRM used on both HD DVD and Blu-Ray movies has been circumvented. A hacker by the name of muslix64 has released a tool called BackupHDDVD including its source code, and posted a video at Youtube showing how a movie is decrypted and then played back from a hard disk drive.

According to muslix64 he managed to locate unencrypted decryption keys in the memory while playing back a HD DVD movie on PC. This sounds awfully similar to the first CSS decrypting programs, which used a key obtained from a poorly designed DVD playback software to decrypt DVD movies. The BackupHDDVD package made available does not, however, include the decryption keys.

A new version of the software is scheduled for early January, which will hopefully shed some light on how the decryption keys are obtained. If there's a vulnerability in PowerDVD that allows the keys to be extracted, the software will most likely be removed from the list of allowed playback keys in future HD DVD movies. Nevertheless it will always be possible to extract the decrypted data stream in some manner as long as computers and operating systems are "insecure" (from software's point of view).

With the AACS decryption method out in the wild, it will probably not take too long until HD DVD movies surface on the Net and P2P networks.

If you're interested in the software, you can download it from our download server here. Basically all it does is decrypt the AES encryption on the movie using a key from TKDB.cfg config file.

I knew a movie projector operator that used a HD camcorder from the projection room to copy movies....until he got caught.. I was talking about in one's living room, in the privacy of one's own home and recording the movie there. It works well, is faster than using ripping tools and it is easy to go from a camcorder to a computer, convert video format and write to a DVD. A digital High definition camcorder works the best but any camcorder will work... If one doesn't drink or smoke too much, the tripod shouldn't fall over..but, at home, one usually has a second chance.... [ + quote]

using a camera on a tripod is a good idea guys, but for me if i want to enjoy a movie i'll enjoy it by watching high quality especially for the sound. so the softwares still alot better. using a capture device i don't think it will work cuz you can't decrypt the code, you gonna see always flicker in the image..i think so [ + quote]

Last time i checked BR was supposed to use CPS which is totaly different from AACS which would mean that it would take much longer to crack BR Copy protection. After some research it seems the BR camp went back on its own decision and went for AACS. This means that BR camp has fucked up something else! [ + quote]

Further more you are not completely correct it has a Blu Ray DRIVE not movie, it plays Blu Ray movies. America's education system has failed yet another soul. [ + quote]

Let's just look at the situation logically. By the time any of us PS3 owners can even afford a Blu-ray burner (especially after the hit we took on the PS3 itself) and then are willing to pay the price for a blank Blu-ray disc, it will be WAY cracked open by then. Figure even if it were cracked today, and someone HANDED you a drive free of charge, would you pay $40 for a blank disc or just buy the movie for $26? It's simple economics... by the time the discs are at least 75% less than the movie costs, it will be cracked. [ + quote]

Don't think he was talking about a movie. I think he/she was talking about DRM... as far as I know this is only a rumor, although a link would be nice. Although my 110 gig hard drive only would fit one... Crafty [ + quote]

Yeah I guess there was some footage on youtube but it's gone now. Or at least it's newly relocated post hasn't been listed here yet. Typically when they ban a movie, the person just uploads it again. [ + quote]
