Hackers Uncover Trains Designed to Fail in Poland

In an unusual right-to-repair battle, members of the ethical hacking group Dragon Sector discovered deliberate software locks in Polish trains that caused them to "brick" when serviced at independent repair shops.

The manufacturer, Newag, has denied the allegations and threatened legal action, but hackers successfully restored the fleet to service by uncovering a hidden "unlock code" within the trains' control panels.
