In March 2022, a ferry operated by Borholmslinjen (Borholm Line) experienced a two-hour delay due to a GPS jamming incident. The disruption was caused by jamming equipment allegedly hidden in two Eastern European trucks onboard the vessel. The malicious interference rendered the ferry’s GPS navigation system inoperable, posing risks to scheduling, passenger safety, and operational efficiency. The issue resolved only after the trucks disembarked, confirming their role in the sabotage. While no data breach or direct financial theft occurred, the incident highlights vulnerabilities in critical maritime navigation systems to cyber-physical attacks. Such interference could escalate to more severe consequences, including collisions, grounding, or prolonged outages, especially if exploited in high-traffic or hazardous routes. The attack underscores the growing threat of electronic warfare tactics targeting civilian infrastructure, with potential cascading effects on logistics, trade, and public trust in transportation safety.
