Polish Hackers Repaired Trains the Manufacturer Artificially Bricked. Now The Train Company Is Threatening Them (www.404media.co)

In one of the coolest and more outrageous repair stories in quite some time, three white-hat hackers helped a regional rail company in southwest Poland unbrick a train that had been artificially rendered inoperable by the train’s manufacturer after an independent maintenance company worked on it. The train’s manufacturer is now threatening to sue the hackers who were hired by the independent repair company to fix it.

After breaking trains simply because an independent repair shop had worked on them, NEWAG is now demanding that trains fixed by hackers be removed from service.

Apparently there was some kind of gps geo fencing going on - that the software detected the train went into an uncertified repair yard and bricked the thing. So I assume the hackers just purged that info, or unset the flags that denoted the brick condition so as far as the train software was concerned it was operating normally.

It's an interesting hack but there is a safety aspect to this too. A train is a complex machine that could go catastrophically wrong and kill a bunch of people. It's not quite Boeing 737 levels of safety criticality but neither is it something that should be taken lightly with regards to service procedure or parts procurement. So the manufacturer were being dicks to brick the train. But the train operator using an unauthorised repairer who might not have access to, let alone follow the correct servicing procedures or parts is not good either.
