This MKBv4 protection apears on the latest HD movie releases (Transformers, Spiderman movies, etc) MKBv4 is an updated version of the special code placed on the Blu-ray media that is essential for the authentication and thus the reproduction of Blu-ray movies on updated Blu-Ray players. Slysoft announced that it would support all MKBv4 discs in a future release of the software.

"SlySoft was recently honored by AACS-LA, being declared as public enemy number one in the ongoing battle for copyright protection. To prove them right and to take on the challenge, SlySoft has just released the latest AnyDVD version which beats the latest 4th generation HD-DVD and Blu-Ray copy protection MKBv4, which was expected to be unbreakable. All that AACS-LA has to offer now is BD+, but even that is on the verge of being circumvented and a release is expected by the end of this year," according to SlySoft.

BD+ is a content code that interacts with the Virtual Machine found on Blu-Ray players & 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). But until now, it is uncertain whether this title-specific security code (BD+ content code) will be included by Studios on a title-by-title basis. In that case, breaking the whole protection scheme would be more complicated, according to CDRinfo.com

James Wong, Head of development at SlySoft: "We already found a way to crack BD+ and we have just turned to fine-tuning. I should really think about hiring a bodyguard now, since this product won't please everybody."

"One could start feeling sorry for the poor movie industry guys, but in the end, it saves their jobs and ours. Actually, they could be grateful and show a little bit more appreciation. Beating AACS-LA's protection was a challenge that we accepted passionately, since winning feels a lot better if the opponent is almost as strong as we are. However, I wonder when people will understand that more restrictions, pressure and protections that prevent things from working won't generate more but less revenue. Microsoft's revenue in the 90ies prove us right and even Apple recently released a DRM-free iTunes version," said Giancarlo Bettini, CEO of SlySoft.
