DVD Video, Content Scrambling System: ❌
Blu-ray Video, AACS v1: ❌ (Free Speech Flag) — props to muslix64 Ultra HD Blu-ray, AACS v2: ❌ ... and already nearly obsolete by intel removing SGX from gen. 11+ media.ccc.de proudly presents a demonstration on the 37C3 (37th Chaos Communication Congress) that AACSv2 on Ultra HD Blu-ray has been broken too (YouTube video) The core attempt is breaking Intel SGX using side channel attacks and emulating the authentication in Python on a RasPI. Minute 25: Wait ... did CyberLink accidentally ship their software debugging implementation with PowerDVD 20 Ultra? Last edited by LigH; 12th February 2024 at 16:49. |

And because that was not the only attack vector, intel discontinued the support of SGX in newer CPUs already. BleepingComputer: New Intel chips won't play Blu-ray disks due to SGX deprecation |
