Poland investigates hacking attack on its state railway network.

Polish authorities announced that the Internal Security Agency (ABW) and police are investigating a hacking operation that caused disruption of train traffic overnight across parts of north-western Poland. Officials reported that automated radio frequencies normally used for rail-traffic management were abused to issue emergency stop commands, halting 25 trains across four regions and triggering delays. The deputy national coordinator for special services, Stanisław Zaryn, stated that the incident is being treated seriously in the context of recent attempts by Russia to destabilise Poland. The disruption targeted transportation infrastructure that is critical not only for civilian mobility but also for military logistics corridors supporting Ukraine. Although the specific perpetrators have not been publicly confirmed, Poland’s security services flagged the event as part of the hybrid-warfare environment where adversaries exploit the blur between civilian and military infrastructure. The dynamics illustrate how Russia’s hybrid operations include digital sabotage of allied logistical lifelines absent overt bombing or air incursions.
