Slashdot, Engadget, and others are reporting that there are now at least 16 Blu-ray titles that cannot be cracked by SlySoft because of updated / upgraded BD+ programming on the optical disc. The Engadget article also presents a useful BD+ architecture drawing.
As I've noted earlier, the BD+ VM-based programmable security technology can be adapted to particular attacks. I would not surprise me if the weakest implementation was put out there originally as a kind of "honey pot" to see the kinds of attacks pirates used. Having done that, it's not surprising that BD+ has been resealed. This "cat and mouse game" will go on indefinetely.
