  • •Ransomware incidents have disrupted cargo operations, revealing vulnerabilities in maritime systems.
  • •Human error is a significant factor in vessel cyber incidents, accounting for 26% of cases in 2024.
  • •Ports are shifting towards collective cyber resilience strategies to enhance incident detection and response.

The maritime industry faces increasing cyber risks as digital systems become integral to operations. Recent ransomware attacks, such as the one in July 2023 at the Port of Nagoya, disrupted cargo handling and highlighted vulnerabilities in interconnected systems. The UK P&I Club and CyberOwl identified seven insecure behaviors that contribute to cyber incidents, with human factors linked to 26% of vessel cyber incidents in 2024. The Port of Algeciras is also addressing cybersecurity challenges, emphasizing the need for collective resilience among port ecosystem members. The reliance on digital technologies raises concerns about operational continuity and the potential for significant disruptions in maritime traffic and logistics.
