Latest BD+ Protection Broken Again


Slysoft has released a new version of its Any DVD HD software that is able to break latest version of the Blu-ray's BD+ protection as well as disable the BD-Live features of the latest Blu-ray titles.

It is not the first time that Slysoft's Any DVD HD software defeats the BD+ feature. The first announcement came in October 2007 with the release of a version that could bypass the 4th generation HD DVD and Blu-Ray copy protection (MKB v4) as well as BD+ found in the high-def movie releases at that time.

According to the company, the new version of its AnyDVD software is capable of bypassing the latest version of the BD+ protection technology.

BD+ is a content code that interacts with the Virtual Machine found on Blu-Ray players and decides whether the player is hacked. According to the BDA, to successfully attack the BD+ system, pirates would have to overcome the AV content security system (e.g. extract AACS keys) and also overcome title-specific security code (e.g. reverse engineer security code). Studios add this title-specific security code (BD+ content code) on a title-by-title basis.

In addition, the new version of the software can disable the BD-Live features of the Blu-ray discs. BD-Live automatically downloads several megabytes of additional content other than the main movie, such as "extras" or "audio comments", over an online connection.

Slysoft claims that BD-Live may add confusion to the Blu-ray owners since a significant number of Blu-ray players do not provide the option to disable BD-Live at the user's request: the supposedly extra Blu-ray content fires off and automatically downloads without asking the user's permission. And so, many film fans are left to sit puzzled, oblivious to the reason why it is taking long for the film to finally begin playing.

Slysoft also claims that the BD-Live's interactive procedure may also allow studios to gather information and as a result, know exactly how often and when their disc buyers are looking at which film.

Peer van Heuen, the head of development at SlySoft, indicates, "when we took a closer look at the first of these disk types we were absolutely dumbfounded. Sometimes the films actually contacted the manufacturer and did so with the user not knowing about it or even being in a position to recognize that a download connection was taking place. I assume that a significant percentage of these film buyers don't know what to make of the little BD-Live logo on the package or even recognize what that logo implies."

Based in Antigua in West Indies, Slysoft is not affected by the copyright laws of the U.S. and European countries.

Slysoft is not the only company famous for its copy protection circumventions. According to some threads in forums like Doom9, there ios also another tool that bypasses the BD+ protection. A Doom9 member named 'Oopho2ei' discovered the way to bypass the BD+ code while it is running in a Java-VM. "I am glad to announce the first successful restoration of the BD+ protected movie "The Day After Tomorrow" in linux," the user wrote in a forum thread. "It was done using a Blu-ray drive with patched firmware (to get the volume id), DumpHD to decrypt the contents according to the AACS specification and the BDVM debugger from this thread to generate the conversion table. The conversion table is the key information to successfully repair all the broken parts in m2ts files to restore the original video content," the used added.

According to the post, both protections of the movies 'I Robot' and 'The Day after Tomorrow' have been broken.
