A trio of Polish security researchers claim to have found that trains built by Newag SA contain software that sabotages them if the hardware is serviced by competitors.
Newag, a Polish train maker, emphatically denied that it installed such software in a statement [PDF, Polish] issued Wednesday, attributing any issues to unknown hackers.
The rolling stock and engineering business insists its software is correct and that it did not design the trains’ programming logic to fail under specific conditions, as has been claimed. “This is a slander from our competition, which is conducting an illegal black PR campaign against us,” it protested.
