First AACS Blu-Ray/HD-DVD Key Revoked
Thomas Charron writes "An update posted for Intervideo WinDVD 8 confirms that it's AACS key has been possibly revoked. WinDVD 8 is the software which had its device key compromised, allowing unfettered access to Blu-Ray and HD-DVD content, resulting in HD movies being made available via many torrent sites online. This is possibly the first known key revocation which has taken place, and little is known of the actual process used for key revocation. According to the release, 'Please be aware that failure to apply the update will result in AACS-protected HD DVD and BD playback being disabled,' which pretty much confirms that the key revocation has already taken place for all newly released Blu-Ray and HD-DVD discs."
Put simply: industry + clueless = idiots who damage their own profits. The music industry has proven this well already -- now it's time for the movie industry to not learn from the past.
And the update must have the new key in it!
And we know how smart InterVideo have been about protecting the keys so far...
The fact of the matter is that if it can be decrypted and the user has physical access, there is *no way* to make "unbreakable" DRM. None. At all.
Especially on most modern CPU architectures where memory and the bus are unencrypted. The data *has* to go through RAM and over the bus.
Therefore there *is no protection*
It takes *one* decrypt to defeat their supposed purpose "keeping them dirty pirates from getting it" and this decrypt will *always* happen. But yet they waste millions in R+D money making ridiculously bad systems to try to prevent something that's physically impossible to prevent.
It's a networked device. They'd just put out a firmware update. Sorry to shatter your dreams.
It would be more interesting to find out what would happen if the key to the Sony standalone BluRay players was discovered.
It should be a lot more difficult to get the keys for a hardware player than for a software player. WinDVD made an easy target because it is running on a general-purpose computer, which means that the key is sitting there in memory at some point to be snooped out. It's not easy, I'm sure, to find that key among the many megabytes of code, but it's there.
A hardware player isn't a general purpose computer. I'm sure it's possible for somebody with the right hardware to snoop inside its memory (say, inserting a special thingamabob between the memory and the mother board that allows you to read all reads/writes as they go past), but it's not going to be readily available.
Presumably somebody will be the first one to do this, and that is sure going to be a bad day for both formats. People are prepared to upgrade their software; it happens all the time and it's a relatively painless process for most people. Upgrading your hardware is not going to be easy, and it may not even be possible. (I used to own a DVD player which was "upgraded" by downloading a patch, burning it onto a CD, and putting that in the machine, but I don't know if every DVD player supports that.)
If they start denying keys on hardware players, there will be a world of pain, but I don't expect this to shatter the world. They'll just advise everybody to download a patch with a new key.
...and certainly not the last. Beware, HD-DVD/Blu-Ray consumers, you're in for a bumby road of software patches and exploits that move twice as fast!
You know, it's the damnedest thing. My computer is controlled by me. Everytime I see people whining about DRM I wonder what the fuss is. I run Windows XP and have had no issues with DRM because I don't buy DRM'd media. Instead of whining, I just put my money where my mouth is and so far I haven't fallen asleep cursing Microsoft or anyone else because I don't have any DRM issues to speak of. It's God Damned amazing.
