In December of 2023 white-hat hacker group Dragon Sector revealed their findings regarding Newag Impuls rolling stock malfunctions. They were employed by SPS Mieczkowski (Serwis Pojazdów Szynowych Mieczkowski) to investigate issues they were having regarding repair of Newag Impuls trains. After getting access to debug port, copying contents of management computer and reverse engineering the result code, they found multiple flags that were tripped from zeroed values. After correcting those and reinserting the computer to the train it have returned to normal function. Then they proceed with analysis of the code. In their findings they presented multiple instances of GPS coordinates that were pointing to the competing service companies. After detecting extended stay at these coordinates (10 days) the train were to lock up and the only repair option was to send the train for service to producer facility. In the code of different computers the group also found parts serialization and arbitrary timed component malfunction. After these findings investigation and court case was initiated against the company and as of August 2025 they have not yet reached the conclusion. | In December of 2023 white-hat hacker group Dragon Sector revealed their findings regarding Newag Impuls rolling stock malfunctions.
