The guys at the Doom 9 forum are marking February 11, 2007 as the day when digital rights management was defeated on Blu-ray and HD DVD discs. It turns out that cracking the high definition disc formats was much easier than was originally thought. The processing key that can unravel the DRM on all HD DVD and Blu-ray discs has been found by a clever encryption fighter named arnezami.
It gets better:
The first-reported cracks for HD DVD and Blu-ray discs were not completely effective, because each individual title had secret codes that were needed to unravel the rest of the encryption on that disc. But now this newly-found processing key is apparently the holy grail that unlocks the DRM on all HD DVD and Blu-ray discs released so far. The guy found it by simply watching his computer memory, where the secret code—which we won't publish here for fear of doing jail time—simply appeared. Incredible. Let the free downloads begin!
