1. The Growing Cybersecurity Crisis in the Maritime Industry

The maritime industry across the globe is witnessing an unprecedented increase in cyber threats, especially with the increasing use of digital technology within maritime operations. According to a report highlighted by Cydome, there has been a 150% increase in operational technology cyberattacks on maritime infrastructure during 2025, which is a significant change in the maritime cyber threat landscape. As maritime operations become increasingly connected through satellite communications, such as IoT-based monitoring, there is a new threat emerging within maritime infrastructure, which is not only impacting IT operations but also affects vessel operations, making it a crucial part of maritime safety.

2. Ransomware Dominates the Maritime Threat Landscape

One of the most alarming findings of the report released on Industrial Cyber is that ransomware attacks account for almost 87% of maritime OT cyber incidents. Cybercriminals are increasingly attacking operational technology, which controls technology on ships, logistics, and even infrastructure at ports. The attacks can disrupt international trade, cause delays, and even threaten the physical integrity of ships. Most of the attacks occur after attackers gain access to computer networks, often through flawed remote access tools, before deploying ransomware attacks on operational networks. As ransomware attacks become increasingly sophisticated, maritime organizations should take proactive measures against operational downtime and financial loss.

3. GPS Spoofing and Navigation Manipulation

In addition to ransomware, hackers are also taking advantage of vulnerabilities in navigation systems. According to the report, there has been a significant rise in GPS spoofing attacks, with around 1,000 cases occurring on a daily basis, affecting around 40,000 vessels. GPS spoofing is a type of attack where the GPS is manipulated, and a ship may be misled into thinking that it is in a different location than it actually is. GPS spoofing can cause navigational problems, disrupt maritime logistics, or even lead to a geopolitical crisis in disputed waters. With the rise in digital navigation systems, the security of GPS systems has now become a key priority in maritime cybersecurity.

4. The Role of AI and Expanding Attack Surfaces

This digitalization has created new risks, especially in the maritime industry, where digital technologies are increasingly being used on ships, from satellite communications to IoT devices and edge devices. According to the report, there has been a rise in attacks on routers, VPN gateways, and firewall devices, with increases of up to 800%. This is because cybercriminals are taking advantage of the fact that many edge devices are not properly secured. The rise of AI-based hacking tools is also helping cybercriminals discover vulnerabilities in systems, and this is helping them find vulnerabilities in critical systems quicker than ever before.

5. Visibility Gaps and Security Challenges in OT Environments

Another significant issue that has been identified in the research is the issue of a lack of visibility in operational technology systems. Only 13% of maritime organizations claim that they have full visibility into their OT systems, while a further one-third claim that they have little or no visibility into their operational assets. The absence of adequate visibility into OT systems creates a situation where it is difficult for maritime organizations to detect and respond to cyber threats and attacks. Additionally, around 50% of OT threats and attacks are a result of unauthorized external access, usually from a third-party source or remote access.

6. Strengthening Cyber Resilience with Strategic Security Support

As the number of cyber attacks on critical infrastructures continues to grow, it has become imperative for maritime organizations to develop a proactive cybersecurity strategy to address the emerging risks. This involves constant vulnerability management, real-time threat detection, as well as the development of response strategies to address the risks. Sprit Network is helping organizations address the emerging cyber risks by providing the necessary cybersecurity solutions, risk management, as well as cybersecurity monitoring services to protect IT as well as OT infrastructures from the growing ransomware attacks, AI-based cyber attacks, as well as other emerging cyber risks in the maritime industry.
