* Polish train maintenance company, SPS, was getting suspicious as trains made by a company, Newag, kept on "randomly" breaking and couldn't be fixed. They was getting fined millions by Polish government as they had a contract that fined them for being too slow with repairs.
* They secretly hired literal hackers (Dragon Sector) for 2 months to dig around Newag train code.
* Hackers found out some incredible things, generally that fit under the umbrella of "late-stage capitalism", or more specifically, corporate protectionism, sabotage, ransom, etc.
Some examples of the secret code that the hackers found:
* Breaks the trains if they go into geo polygons that are right around the warehouses of 5 Polish train maintenance companies, including SPS.
* Breaks the trains after 1 million kilometers.
* Breaks the trains if they don't move for 10 days.
* Secret button press combination (basically Tekken, Street Fighter, etc.) to disable the "malfunctions".
