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.

If you own the disc, the argument is simple: AACS does not stop piracy. Pirates simply download the decrypted file from Usenet or Torrents within hours of release. AACS only hurts legitimate owners who want to use Plex, Emby, or Jellyfin to watch their movies on an iPad or a smart TV that lacks a disc drive. 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. The implementation was sloppy

The software that protects your right to back up your $30 4K disc is the same software that your antivirus might flag as "hacktool" – not because it is malicious, but because it injects code into optical drive firmware. If you own the disc, the argument is

Prior to LibreDrive, your Blu-ray drive’s firmware was an enemy. The firmware was programmed to refuse reading certain areas of the disc if the AACS handshake failed.

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).

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.
