1/2 In June 2022 Polish train repair shop Serwis Pojazdów Szynowych #SPS asked the ethical hacking group #DragonSector for help after their trains had "mysterious failures", leaving the trains completely unusable. Analysing the train's software, the hackers concluded that the train manufacturer bricked the trains on purpose because the train was taken to an independed repair shop.
@Fnordinger @q3k oh, I was not aware, thanks for the hint!

The three involved hackers #Redford, #q3k and #MrTick gave a talk on the 37th Chaos Communication Congress #CCC to tell how they managed to break the company's #DRM to get the trains to work again: https://media.ccc.de/v/37c3-12142-breaking_drm_in_polish_trains
