As Ports Get Smarter, They Become More Vulnerable to Cyberattacks

Global maritime hubs are undergoing a rapid digital transformation, embracing automation, IoT, AI, and big data to boost efficiency and capacity. However, this evolution into “smart ports” also introduces a significant and growing threat: heightened vulnerability to cyberattacks. Recent incidents and warnings from organizations like NATO highlight an escalating risk that could cripple global trade and national security.

Modern ports are complex ecosystems, relying on interconnected Information Technology (IT) and Operational Technology (OT) systems to manage everything from vessel traffic and cargo handling to customs declarations and supply chain logistics. While these digital advancements offer undeniable benefits, such as optimized routes, reduced human error, and real-time tracking, they also create an expansive “attack surface” for malicious actors.

A new policy brief from NATO’s Cooperative Cyber Defence Centre of Excellence (CCDCOE) reveals that nearly all NATO and partner countries have experienced cyberattacks on their port infrastructure in the past five years. These attacks are not merely theoretical; they range from crippling ransomware incidents, like those seen at Japan’s Port of Nagoya in 2023 and India’s Jawaharlal Nehru Port Terminal (JNPT) in 2017, to sophisticated GPS spoofing and Distributed Denial-of-Service (DDoS) campaigns that disrupt operations at major European ports.

The threats come from a diverse range of actors, including state-sponsored groups from Russia, Iran, and China, financially motivated cybercriminals, and politically driven hacktivists. Their tactics are increasingly sophisticated, involving spear-phishing, malware, ransomware-as-a-service, and even the manipulation of critical navigation and communication systems. The 2017 NotPetya malware attack, which caused an estimated $300 million in losses for shipping giant Maersk and impacted key global ports, serves as a stark reminder of how interconnected systems can spread damage far beyond an initial target.

A significant concern highlighted by the CCDCOE is the disconnect between civilian-controlled commercial ports and military cybersecurity strategies. Despite their crucial role in global trade and defense logistics, many ports lack formal integration into national and international cyber defense frameworks. This “civil-military gap” creates serious vulnerabilities, leaving vital infrastructure susceptible to hybrid warfare tactics.

Experts are calling for urgent reforms, including updating NATO’s maritime strategy to fully incorporate cyber defense, establishing dedicated liaison roles between military commands and port cybersecurity authorities, and creating structured intelligence-sharing networks. As ports continue to digitalize, robust cybersecurity measures, complete incident response plans, and continuous training for personnel are no longer optional but essential for safeguarding the arteries of global commerce.
