Doom9 Researchers Break BD+ 345

An anonymous reader writes "BD+, the Blu-ray copy protection system that was supposed to last 10 years, has now been solidly broken by a group of doom9 researchers. Earlier, BD+ had been broken by the commercial company SlySoft." Someone from SlySoft posts a hint early in the thread, but then backs off for fear of getting fired. The break is announced on page 15.

Analyst Says Blu-ray DRM Safe For 10 Years 493

Mike writes to let us know that a poster on the AVS forum says that the latest issue of HMM magazine (no link given) contains a quote from Richard Doherty, a media analyst with Envisioneering Group, extolling the strength of the DRM in Blu-ray discs, called BD+. Doherty reportedly said, "BD+, unlike AACS, which suffered a partial hack last year, won't likely be breached for 10 years." He added that if it were broken, "the damage would affect one film and one player." As one comment on AVS noted, I'll wait for the Doom9 guys to weigh in.

AACS Cracked Again 306

EmTeedee sends us to a blog post for a summary of the latest results in cracking AACS, from the Doom9 forums (as the earlier cracks have been) — after the DVD Security Group said it had patched the previous flaws. From the DLTV blog: "This time the target was the Xbox 360 HD DVD add on. Geremia on Doom9 forums has started a thread on how he has obtained the Volume ID without AACS authentication. With the aid of others like Arnezami they have managed to patch the Xbox 360 HD DVD add on... It appears that XT5 has released [an] application that allows the Volume ID to be read without the need to rewrite the firmware. This would mean that anyone could simply plug in the HD DVD drive and obtain the Volume ID from any HD DVD without the hassle of flashing it."

Decryption Keys For HD-DVD Found, Confirmed 473

kad77 writes "It appears that, despite skepticism, 'muslix64' was the real deal. Starting from a riddle posted on pastebin.com, members on the doom9 forum identified the Title key for the HD-DVD release 'Serenity.' Volume Unique Keys and Title keys for other discs followed within hours, confirming that software HD-DVD players, like any common program, store important run-time data in memory. Here's a link to decryption utility and sleuthing info in the original doom9 forum thread. The Fair Use crowd has won Round One; now how will the industry respond?"
