Slysoft promises AnyDVD will crack future HD-DVD/Blu-Ray discs

AnyDVDThere's a cat and mouse game that goes on between those who produce professional videos and those who want to watch those videos on their own terms. Every time the folks behind DVDs, Blu-Ray discs, or HD-DVDs serve up a new DRM scheme, hackers go to work trying to figure out how to circumvent that encryption.

You can look at this as a noble or malicious act: either the hackers want to make sure you can watch the movie on any machine you choose, or they want to make sure you can upload the videos to file sharing sites. The reality is probably somewhere in the middle.

Earlier this year SlySoft released a commercial application for ripping HD-DVD and Blu-Ray discs. The only problem is that disc manufacturers could keep offering up new encryption keys that would make the software obsolete.

Now SlySoft has released an updated version of AnyDVD that it says it "future-proof," because it includes an artificial intelligence agent that figures out how to strip DRM from movies even if those movies are encrypted using a previously unknown key.

Update: It looks like the "AI Scanner" only works with DVDs, not HD-DVDs and Blu-Ray discs. Considering it's been pretty easy to rip DVDs for some time now, that makes this "future-proof" guarantee a bit less exciting.

The funny story of the latest AACS key leak


Boing Boing reports a story that will go down in the book of hacker lore about the leak of the latest AACS key. It seems that weeks before the latest leaked key began to make the rounds on the Doom 9 forums, it was first released in an inauspicious and sly way which, for geeks like us, is actually kind of funny.

Ed Felton of Freedom To Tinker satirized the idea of "protecting" a number with his 128 bit number generator, which issued unique numbers to all who asked for one. The comment section became a stream of people threatening legal action if anyone else published their number, but in amongst the smart-assery was a hidden gem:

Here's mine:
45 5F E1 04 22 CA 29 C4 93 3F 95 05 2B 79 2A B2

What are the odds that this is the new processing key?
(Hint for arnezami: uv=00000047)

Amezami is the name of the hacker who originally leaked the first key and, as it turns out, that is the next compromised key in the AACS chain. The odds that Felton's toy picked that number at random are pretty slim so, who took the cookie from the cookie jar?

HD-DVD key numbers turned into colors on a T-shirt

HD-DVD TYou know those numbers that could change the world? No, not the ones on Lost, the HD-DVD key code that could lead to the end of Digg as we know it.

Well, the sixteen hexadecimal digits are just numbers when it comes right down to it. And you can do all sorts of things with numbers, like use them as a basis for web-colors and make them into a pretty picture that may or may not be illegal to share with your friends.

But why stop there when you can go one step further and design a T-shirt based on those colors and sell it for fun and profit? It'll be interesting to see if the T-shirt gets a cease and desist notice from the MPAA, or if they'll send out letters to anyone caught wearing the shirt in public.

HD-DVD key fiasco is an example of 21st century digital revolt


It's the most circulated number of the week. Sixteen hexadecimal digits that unlock the wonder of most currently released HD-DVD titles from the surly clutches of the AACS revenue content protection system. Sixteen digits that have been posted in so many places -- and in many cases, removed only to be reposted -- that they're hard to avoid.

Cory Doctorow's class blog for his USC course, "Pwned: How everyone on campus is a copyright criminal" was served a DMCA takedown notice and, on the advice of counsel, removed the offending digits. They were posted to Wikipedia, then removed and locked from reposting. Then the diggstorm came. A slew of digg stories containing the forbidden digits have been posted, made the front page and been removed, only to start again.

Witness the modern equivalent of the 95 thesis' Martin Luther nailed to the door of Wittenburg church. We, digital citizens --commonly referred to by the vulgar term of 'consumers' -- have had enough of content lock-in. We've bought and re-bought entertainment media -- repackaged and regurgitated digital vomitus -- until we're blue in the face. We've been told time and time again that DRM is for our own protection, and we're finally and inconsolably fed up.

As Joe Rogan's character on Newsradio once quite accurately quipped, "Dude, you can't take something off the Internet.. that's like trying to take pee out of a swimming pool." The content providers have attempted to do exactly that, remove pee from the proverbial swimming pool that is the Internet and, as we've witnessed so many times before, they've failed miserably.

The bottom line remains, we as consumers, want our content free (as in Freedom) and if we don't get it, we'll take our content free (as in beer).

First Blu-Ray/HD-DVD key revoked


And the saga continues. The content protection system used on next generation HD capable DVD's (AACS) was recently compromised through an exploit in the popular WinDVD software made by Intervideo. In a departure from the standard definition DVD encryption spec (CSS), AACS allows for the publishers to revoke keys handed out to specific licensees, if those licensees somehow misbehave or compromise the system.

Due to the revocation, WinDVD users must upgrade to a new version -- containing a new key -- if they want to watch the HD-DVD's they own.

DeCSS rendered useless the entire CSS system on first gen DVD's, making copying, ripping and backups a trivial procedure. So far, the AACS equivalent remains elusive. However, you can bet that someone somewhere is hard at work on a way to compromise AACS again, either in a short term single key crack -- like the one we've seen here -- or a longer term, system wide crack. There isn't a single known DRM system worth cracking that hasn't been cracked, multiple times; AACS will likely be no different.

Surprise! MPAA not too happy about BackupHDDVD

HD DVDWell, who would have seen that coming? Apparently the Motion Picture Association isn't particularly happy about BackupHDDVD, a tool developed by the hackers over at the doom9 forum that decrypts AACS encryption on HD DVDs.

The MPAA sent a notice to SourceForge, asking them to take down all the files related to the program, and SourceForge complied. That's not to say that you can't find the files if you know how to look for them. But as the folks at doom9 point out, Antigua-based SlySoft has also released software that allows users to decrypt HD-DVD discs without any repercussions, so perhaps BackupHDDVD will eventually wind up with an off-shore home.

While there's some question about whether BackupHDDVD actually infringes on any copyrights or simply utilizes AACS, the truth of the matters is it's unlikely the developers have the resources to fight a legal battle.

Microsoft Vista DRM subverted

Within the past month, both HD DVD and Blu-Ray's AACS protection scheme has been bypassed, and now news has broken of a researcher cracking Vista's DRM scheme. Mind you, Vista just barely hit the shelves. Boing Boing sums it up very nicely:

"As with previous multi-year DRM development efforts, this one disintegrated like wet kleenex on contact with the general public. Now that Vista, HDCP, Blu-Ray and HD-DVD are all broken, it seems like the millions of dollars and thousands of work-hours sunk into these systems was mis-spent. The only benefit that these anti-copying systems confer to the companies that developed them is the right to sue competitors -- and that benefit could have been had by shellacking a one-atom-thick layer of token DRM onto their systems, just enough to be able to invoke the DMCA. Everything else was just gold-plating, wasted money."

So the trend continues. Anything meant to be protected will always be cracked, it seems. Researcher Alex Ionesco's hack bypasses Vista's anti-copying technology and allows for full-res, unencrypted high-def video streams. Due to legal concerns, he has not yet released his code, so it is unknown what will become of his hack. And how will companies respond to the prompt obsolescence of their copyright protection schemes?

First HD-DVD rip shows up online

SerenityWell, the controversy over whether BackupHDDVD actually does anything like, you know, ripping HD-DVD movies appears to be over. Several movie rips, including Serenity have already made their way to BitTorrent trackers.

The breakthrough came when members of the Doom9 Forum tracked down several unique memory keys that BackupHDDVD needs in order to decrypt HD-DVDs. Apparently the keys for King Kong and 12 Monkeys are also available, although Serenity appears to be the only movie to have made it online so far.

The video file is in EVO format and takes up 19.6GB, meaning it will take a very, very long time for most users to download. At that rate, you might as well just spend the $20 to get a copy from Amazon.

While it was inevitable that hi-def video rips would show up online, I'm much more impressed that we now have evidence that the HD-DVD encryption scheme actually has been cracked, and users who want to make backups of videos they've purchased for home use may be able to use software to do so.
