 Lila Beleuchteted Raum, eine Person steht 20m entfernt mit dem Rücken zur Kamera

The last time I did a CCC event retrospective was 4 years ago. I skipped 36c3 for reasons, but with 37c3 I’m back. I wasn’t in Hamburg this year, and I’m not sure if I want to join 38c3 in Hamburg, but time will tell.

But let’s start with the talks I’ve watched and liked. If you think I missed something, please let me know.

Breaking “DRM” in Polish trains

This was the talk that had the most impact in the public media. A team of researchers showed how a polish train manufacturer implemented DRM in their Trains and lied to the customer about it. Trying to get them to only use their own service for maintenance.



The talk from FragDenStaat is a must watch for me. Nice recap what they did since 2020.

Scholz greift durch: Die AfD wird verboten - Deepfakes auch!

This talk by the art collective Politische Schönheit was a nice mix of art and politics. They explained their last project where they created a deepfake of the german chancellor Olaf Scholz. They used this deepfake to create a video where he announces the ban of the german right wing party AfD.
