Polish train manufacturer that lost servicing tender programmed train controller to brick itself after train stays for some time in 6 ISP facilities or in 1 their faculity(for testing?) until undocumented button combination is pressed. Some controller versions brick itself after train is idle for 10 days. After news about this became public, manufacturer removed ability to unlock train by button combination.
Also manufacturer is able to remotely brick train over internet(connected via GSM) at any time.
Mod wanted ONLY article, so enjoy reading in polish.
The manufacturer deflects accusations. They claim that everything the hackers have allegedly found and reported was fabricated per order of the company that was contracted with maintenance of the trains. Apparently, they were behind on a deadline for the mandatory, general check-up of the units. The trains mysteriously didn’t want to work after their reassembly, and their goal would be to allegedly put the blame for inability to repair the fault entirely on the manufacturer, letting them avoid penalties for contract violations.
Both stories sound likely to me, given the business practices in industry nowadays. It’s incredibly outrageous, but also kind of curious. Not the cyberpunk we wanted, but perhaps one we deserve.
I wonder how the story will develop, and which side tells the truth. Funnily enough, I’m on board of one of the manufacturer’s trains as I type this comment. Here’s hoping it won’t strand us in the cold, dark field right now. :)
