4K UHD Blu-rays introduced AACS 2.0. The industry promised this was "unbreakable." It introduced a concept called . In theory, even if you had the keys, your player had to phone home to verify the disc wasn’t a rip.
This post is not a guide to piracy. It is an exploration of the technical arms race between the AACS Licensing Administrator (AACS LA) and the developers who argue that if you own a disc, you have the right to play it on any device you choose.
This creates a massive security risk for the average user. Clones of MakeMKV are rife with cryptocurrency miners and remote access trojans. The real MakeMKV is beta software that requires a constantly rotating "temporary activation key" (which the developer provides for free while it is in beta). makemkv aacs

For the first time, a user could buy a 4K UHD disc on release day and back it up immediately. No waiting for someone to rip the keys online. 4K UHD Blu-rays introduced AACS 2

On the surface, it is a simple tool that converts discs into MKV files. Under the hood, it is a constantly evolving war-room against the Advanced Access Content System (AACS) .

The implementation was sloppy. While the bus encryption was tighter, the underlying Volume Unique Keys were often still stored in memory unprotected. Once a few "leaked" keys for major studio releases hit the internet, MakeMKV could use LibreDrive to grab the MKB and cross-reference it with known keys.
