The maritime industry has long been a cornerstone of global commerce, as evidenced by discussions in the international marine forum, transporting nearly 90% of the world’s trade by volume. With the rapid digitization of ship systems and port infrastructure, cyber threats have become a fast and dangerous reality. Maritime operations are now heavily reliant on interconnected IT (Information Technology) and OT (Operational Technology) systems that, if breached, could result in catastrophic consequences—from economic disruption and data theft to threats to human life. As cyber threats evolve in strength and efficiency, particularly in the form of planned-out cyber attacks, the need for comprehensive maritime cyber risk management measures is more pressing than ever.
What is Maritime Cyber Security?
Maritime cybersecurity refers to the protection of shipboard and shoreside computer and digital systems from cybersecurity challenges and cyber threats that can compromise the confidentiality, integrity, or availability of digital data and processes. These critical systems include navigation systems, communication networks, propulsion controls, cargo management, and crew welfare platforms. The International Maritime Organization (IMO) defines maritime cyber risk as a measure of the extent to which a technology asset could be threatened by a potential circumstance or event, highlighting the importance of effective cyber risk management.
Why Is Safeguarding Maritime Cybersecurity Important?
Safeguarding cybersecurity in maritime operations is crucial due to the high stakes involved, particularly against targeted attacks. A breach could lead to:
- Shipping delays are impacting global supply chains
- Rerouted or hijacked vessels due to manipulated navigation systems
- Compromised cargo manifests, risking loss or theft of goods
- Exposure of sensitive crew and passenger data
- Downtime in port operations is causing massive economic losses
The maritime industry is not isolated and is increasingly targeted by cyber criminals. It interacts with global logistics, oil and gas, defence, and even tourism. Weaknesses in maritime cybersecurity can thus reverberate far beyond the sector itself, impacting overall maritime security and causing severe consequences to critical infrastructure and national economies.
Common Cyber Threats to Maritime Cybersecurity
Several types of cyber threats affect the maritime industry, especially those targeting complex networks :
- Phishing and Spear Phishing: Targeting crew members to gain unauthorised access
- Ransomware: Encrypting systems and demanding ransom for release
- Denial-of-Service (DoS) Attacks: Overloading systems to cause operational failure
- Insider Threats: Malicious or negligent crew actions that lead to vulnerabilities
- Malware: Corrupting or stealing data from shipboard systems
- GPS Spoofing: Misleading navigation systems about location and course
The Rising Cyber Attacks in 2024
According to the 2024 Maritime Cybersecurity Report by MarPoint and Darktrace, cyber incidents in the maritime sector have surged dramatically, impacting the global economy :
- Over 1,800 vessels targeted in just the first half of 2024
- 23,400 malware detections
- 178 ransomware attacks
- Over 50 billion firewall events
Emerging cyber threats include artificial intelligence-powered malware, botnets exploiting IoT devices, and hybrid threats combining physical and cyber tactics. These attacks are more targeted and evasive, exploiting existing cyber vulnerabilities and bypassing traditional security protocols.
Common Concerns in Maritime Cybersecurity
Legacy Systems: Many vessels still use outdated industrial control systems lacking modern security features
IT/OT Convergence: Breaches in IT can now impact OT systems like engine controls and navigation
Shadow Connectivity: Unregulated remote access by vendors and OEMs can create hidden vulnerabilities
Regulatory Gaps: While IMO guidelines exist, enforcement remains inconsistent across jurisdictions
Shortage of Skilled Personnel: Limited cybersecurity expertise among crew members can lead to human error
Most Common Cybersecurity Attacks in Maritime
- Ransomware Attacks: Targeted attacks on logistics firms and shipbuilders are common
- Phishing: Crew emails are compromised to gain access to confidential systems
- Data Breaches: Sensitive cargo and crew data exposed
- GPS Spoofing: Ships misled into unsafe waters
- DDoS Attacks: Ports and vessels are overwhelmed by fake traffic
Cybersecurity Guidelines
The International Maritime Organization (IMO) recommends that cyber risks be appropriately addressed in existing safety management systems. These are based on five functional elements:
- Identify: Threats, vulnerabilities, and impacted systems
- Protect: Control access, update software, and implement best practices
- Detect: Monitor for unusual activity and early threat indicators
- Respond: Establish incident response protocols
- Recover: Plan for data restoration and system functionality
The International Association of Classification Societies (IACS) has introduced two Unified Requirements (URs):
- UR E26: Operational aspects of cybersecurity, including lifecycle plans
- UR E27: Technical specifications for systems to ensure cyber resilience
What Seafarers Must Keep in Mind
- Do not connect unauthorised USBs or personal devices to the ship systems
- Be vigilant for phishing emails or suspicious attachments
- Regularly change passwords and avoid sharing credentials
- Participate in cybersecurity training and drills
- Report any anomalies or suspicious system behaviours immediately
Key Incident in 2024
- MarineMax Ransomware Attack: Rhysida ransomware struck the world’s largest luxury yacht dealer, stealing financial information and company records as well as information from a database of the world’s wealthiest customers. Rhysida put the data up for sale for the price of 15 bitcoin.
These incidents highlight the maritime industry’s vulnerability to cyber risk and reinforce the need for effective cyber risk management.
Actions to Take in Case of a Breach
- Isolate the Affected System: Disconnect to prevent lateral spread
- Notify Authorities and Class Bodies: As per regulatory mandates
- Activate Incident Response Plans: Roles and protocols must be predefined
- Preserve Evidence: For forensic investigation
- Restore from Clean Backups: Ensure the malware isn’t reintroduced
- Conduct a Post-Incident Review: Learn, document, and prevent recurrence
Growing Cybersecurity Concerns with AI and Technology Growth
As maritime operations become smarter, implementing cybersecurity best practices is crucial, as AI introduces both opportunities and threats. AI-powered attacks can mimic crew behaviours, automate intrusions, and adapt to ship defenses. Maritime cyber risk management must now include measures for the protection of onboard systems :
- Monitoring AI-driven anomalies
- Using AI for predictive threat intelligence
- Integrating cybersecurity with automation tools
AI tools must be deployed cautiously to prevent false positives and avoid interfering with critical ship functions.
The Economic Cost of Maritime Cyber Incidents
Cybersecurity breaches in the maritime sector come with significant economic repercussions. From delayed cargo and disrupted port operations to ransom payments and regulatory penalties, the costs can quickly spiral. According to a 2024 industry estimate, the average cost of a maritime cyberattack exceeds USD 550,000, not including reputational damage or long-term customer loss. For high-profile companies, the stakes are even higher such as in the MarineMax ransomware attack, where financial data was leaked and operations stalled. Insurance premiums may rise, investors may lose confidence, and clients may turn to more secure operators. What’s more, the cost of recovery, data restoration, especially for sensitive data forensic analysis, legal fees, and system upgrades, makes the number much larger.
International Collaboration and Regulatory Evolution
Cyber risk doesn’t respect borders, particularly in shipping, which operates globally. As threats increase, cross-border collaboration has become vital. The International Maritime Organization (IMO) and classification societies like IACS and Bureau Veritas are working to strengthen global cyber standards, such as UR E26/E27 and IMO MSC.428(98). Yet enforcement and harmonisation remain patchy, with national policies varying widely. Collaborative efforts like the Global Centre for Maritime Decarbonisation’s cybersecurity initiatives and Singapore’s bunkering protocols demonstrate the value of collective intelligence and shared guidelines.
Safeguarding Ships and Systems: The Necessary Approach
To ensure cyber risk management is strong:
- Use zero-trust access: No one is trusted by default
- Separate IT and OT networks
- Limit vendor access and monitor it
- Conduct audits and cyber drills
- Get cyber insurance
- Set up an ISMS (Information Security Management System) with ISO/IEC 27001
Annual checks and updates ensure resilience across the fleet. Implement an Information Security Management System (ISMS) aligned with ISO/IEC 27001
Only a layered, adaptive approach that mitigates risk exposure can ensure cyber resilience across a fleet.
Conclusion
The maritime industry today needs a comprehensive cybersecurity plan. Digitization promises efficiency but also opens the door to unprecedented cyber threats. As 2024 has shown, the frequency and severity of cyber incidents are rising. Safeguarding ships and systems requires a holistic, proactive, and standards-compliant approach. Seafarers, operators, OEMs, and regulators must work together to build a robust maritime cybersecurity ecosystem. The price of inaction, leading to potential security failures, is too high—economically, operationally, and humanely, making it very important to safeguard shipping.
