AACS 2.0 revision unbeatable by existing 4K Ultra HD Blu-ray ripping tools

A revision of  the AACS 2.0 copy protection, unofficially referred to as AACS 2.1, makes it impossible to rip 4K Ultra HD Blu-ray (UHD BD) discs with all existing tools. The update to the AACS 2.0 copy protection as found on Ultra HD Blu-ray discs has been spotted on the movies Fury and Patriot.

AACS 2.0 revision unbeatable by existing 4K Ultra HD Blu-ray ripping tools

First reports about the revised AACS 2.0 copy protection came in about 2 days ago. Users who tried to rip Fury and Patriot report that MakeMKV crashed when trying to open ‘AACS 2.1’ discs. AnyDVD users report they are unable to connect (error 413) to Redfox’s Online Protection Database (OPD) with the AACS 2.1 protected discs.

DeUHD does a little better, the software also can’t rip the discs, but DeUHD is able to read the discs and create a dump of the disc. The dump can assist the DeUHD developers to further investigate the AACS 2.0 revision.

The copy protection is still so new, and found on so little discs, that it’s impossible to say if, and when, a solution to rip UHD BD discs will become available. But we do know that all software developers are investigating  the new copy protection. Arusoft has stated it has started to work on finding a solution already, Redfox users have submitted the first log files, and MakeMKV users report they’ve also submitted information to the developer of MakeMKV that should help him in analyzing the revised AACS version.

One tool that is also able to rip UHD BD discs, but that hasn’t been mentioned yet is DVDFab. That is because the company uses technology provided by Arusoft, it depends on the latter whether also DVDFab users will be able to rip AACS 2.1 discs in the future.

Users who are in the market for 4K Ultra HD Blu-ray movies, and plan to rip them, should be cautious with movies from Sony. Both Fury and Patriot contain the new AACS revision and are Sony releases.
