Borholmslinjen

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 disabled the ferry’s GPS system, rendering navigation unreliable and forcing operational delays. Once the trucks disembarked, the GPS functionality restored immediately, confirming the source of the interference. The incident highlights vulnerabilities in maritime cyber-physical systems, where electronic warfare tactics such as GPS jamming can disrupt critical infrastructure. While no data breach or financial theft occurred, the attack compromised operational safety, risked passenger and crew well-being, and caused reputational damage due to the publicized security lapse. The deliberate nature of the jamming suggests a targeted cyber-attack, potentially linked to state-sponsored or criminal actors testing maritime resilience. The delay, though temporary, underscores how non-digital attacks on navigation systems can have cascading effects on logistics, trust, and regulatory compliance.
