DVDFab, a software tool for ripping and decrypting DVDs and Blu-ray discs, will not be upgraded to support newer Ultra HD (4K) Blu-ray discs.
Fengtao Software, which makes DVDFab, said in a statement that it "will not decrypt or circumvent AACS 2.0 in the days to come. This is in accordance with AACS-LA, (which has not made public the specifications for AACS 2.0), the BDA [Blu-ray Disc Association] and the movie studios." AACS-LA is the body that develops and licenses the Blu-ray DRM system.
Curiously, Fengtao's announcement comes just a day after SlySoft—the company that makes the ripping tool AnyDVD—ceased operations and vanished from the Web. All that's left is a cryptic message on SlySoft's website: "Due to recent regulatory requirements we have had to cease all activities relating to SlySoft Inc."
