You wouldn’t download a train—but you might conceivably want to repair one. Those worries have led to a massive controversy in Poland, as train manufacturer Newag has come under fire for likely adding DRM-style protection to stop its vehicles from being repaired at competitor facilities.
A company named SPS Mieczkowski received fines from a rail operator when it failed to repair one of Newag’s trains. It decided to then make privateers out of pirates, hiring a collective of hackers called Dragon Sector. Speaking withOnet, one such hacker Michał Kowalczyk said: “We discovered the manufacturer’s interference in the software, which led to forced failures.”
In the talk"Breaking DRMS in Polish Trains", the team stated it was “100% sure” it was in the right, and that “it’s Newag that should be scared, not us.”
To ‘fix’ this, the manufacturer extended the time to 21 days, then added “geofencing” to cause it to lock if it stayed in certain locations, which just so happened to be the main competitors of Newag. One of the locations was even a SPS Mieczkowski workshop—you know, the company that was fined because it couldn’t repair a Newag train? Oh no.

As for the mystery bricks on November 21: “We also had a very nice date check in one of the trains … the train was supposed to be serviced on the 21st of November 2021.” If you’ve been following along, you might be wondering: ‘hold on, didn’t the train break in 2023’? That’s because (as the hackers reveal) the code actually instructs the train to lock down between November 21-30 and December 21-31.

“This is on one train,” says Sergiusz Bazański (alias q3k). “That train is now famous, because it did indeed break on the 21st of December this year. But don’t worry, New Years? It’ll run just fine.”
The entire talk is a journey through a comedy of errors—one that’s eerily familiar. We’ve all seen horrific levels of DRM applied to games that impact performance, tacked on in haphazard ways that harm the player such as infamousresource-hog Denuvo. The only issue is: these are trains, not video games, and the consequences are a little more severe.
It’s also not the first time we’ve seen this kind of thing happen outside of gaming. In August of 2022, ahacker jailbroke a DRM-laden tractorand then ran Doom on it—thwarting John Deere’s remote bricking systems. In July of the same year,BMW also introduced microtransactionsto its cars. Only $18 a month to heat your seats, what a steal.
