Dieselgate, but for trains – some heavyweight hardware hacking

This article is about fixing, but with a twist - it's about fixing trains that their manufacturer sabotaged. :D

In Poland, it took the hacker crew "Dragon Sector" months of work to find a software "time bomb" that was sabotaging "Impuls" trains manufactured by Newag, once their maintenance was handed over to another company.

Let this be a reminder to everyone about closed source technology and critical infrastructure.
