What is Maritime Cybersecurity?
What is Maritime Cybersecurity?
Maritime cybersecurity refers to the practices, technologies, and policies used to protect ships, shipping infrastructure, and associated industries from cyber threats and attacks. Cybersecurity in maritime focuses on unique challenges including the protection of onboard navigation systems, communication networks, and operational technologies that are essential for the safety and efficiency of operations.
Maritime cybersecurity integrates both Information Technology (IT) and Operational Technology (OT) to secure vessels from unauthorized access, data breaches, and other cyber threats. Given the unique nature of OT devices, cybersecurity solutions chosen to protect maritime infrastructure are often purpose made for environments that include OT.
Why Maritime Cybersecurity is Important?
The importance of maritime cybersecurity stems from the critical role that the maritime industry plays in global trade and logistics. Approximately 90% of the world's goods are transported by sea, making maritime security crucial for economic stability and safety. Cyber threats in this sector can lead to significant disruptions, including:
- Navigation and communication systems getting compromised, leading to potential collisions or groundings.
- Unauthorized access to confidential cargo data and other sensitive information.
- Operational disruptions that can cause economic losses and impact the supply chain.
- Increased vulnerability to piracy and terrorism due to compromised security systems.
Given these high consequences, Shipping companies are faced with a range of maritime-specific regulations, including the Maritime Cyber Risk Management and the IMO guidelines, as well as guidelines from the Oil Companies International Marine Forum (OCIMF), the Baltic and International Maritime Council (BIMCO), and the Cruising Lines International Association (CLIA).
This breadth of ever-changing regulations requires a dynamic cyber security solution which can self-learn and provide real-time detection, visibility, and response across the digital ecosystem.
Cybersecurity Challenges for Maritime
The shipping and navigation industry is exposed to a wide range of cyber-attack vectors, with businesses relying on a complex web of systems - from smart devices on remote vessels to IT systems onshore. This includes OT systems used to steer ships and load cargo, with Industrial Control Systems (ICS) involved in the engine control room and navigation lights.
To fuel efficiency, many maritime organizations have integrated their OT and IT systems. But, the sector’s fast-moving digitization and robotization has exponentially increased the number of entry points for cyber-criminals.
While IT and OT convergence opens the door to new risks, it also represents an opportunity to begin approaching security with a holistic mindset in which the entire digital business can be defended in a coordinated capacity.
Common Cyber Threats in Maritime Cybersecurity
- Phishing and Spear-Phishing Attacks: These involve deceptive emails and messages designed to trick maritime staff into revealing sensitive information or downloading malware. Phishing attacks can lead to unauthorized access to the ship’s systems and sensitive data.
- Malware and Ransomware: Malicious software can be used to disrupt the operations of onboard systems, steal sensitive data, or lock out legitimate users, often demanding a ransom to restore access. Ships are particularly vulnerable when they integrate their systems with port and logistics services that may not have robust cybersecurity measures.
- GPS Spoofing: Attackers may manipulate GPS signals to mislead maritime navigation systems about the vessel's location or route. This could potentially lead to accidents or unauthorized detours.
- Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks: These attacks overload a ship’s networks with traffic, making them unable to process legitimate requests and potentially leading to operational failures.
- Unauthorized Access and Insider Threats: Unauthorized access can occur through inadequate security measures, allowing hackers or even insiders to manipulate or steal data. Insider threats also include sabotage by disgruntled employees who have access to the systems.
- Ransomware Attacks: These occur when malware encrypts a victim's files, making them inaccessible unless a ransom is paid. In the maritime industry, ransomware can lock down navigation systems, access to digital logs, or other critical data, severely disrupting maritime operations.
- Supply Chain Compromises: This threat involves a malicious actor infiltrating the maritime industry through less-secure elements in the supply chain. For example, a compromised software update or hardware component can be used to gain access to wider network systems used in maritime operations.
- Data Breaches: Unauthorized access to confidential data can be devastating. For maritime operations, this could involve access to cargo details, ship schedules, or personal information of crew members, potentially leading to operational manipulations or piracy.
- Impersonation: Attackers may pose as legitimate users or officials to gain access to secure systems. In maritime settings, impersonation could involve posing as port officials, ship inspectors, or other entities that have authorized access to sensitive operational data.
- Social Engineering: Social engineering is a technique used by cyber-criminals to manipulate the humans behind machines rather than exploiting code-based vulnerabilities. This can be done by impersonating legitimate parties, targeting vulnerable individuals, building trust with a victim, creating a sense of urgency in a message, and more. Social engineering can be used to enhance phishing, smishing, spoofing, or other cyber-attacks that target humans. Because humans are susceptible to trusting other humans, the goal of social engineering is to present the victim with a seemingly legitimate situation.
Maritime cyber-attack examples
Stopping Malware in its Tracks
Darktrace protected a maritime transportation and storage cargo handling organization in Greenland from a fast-moving malware attack. After being infected, a device was detected making new and unusual external connections on ports 85 and 88. During the activity, the device downloaded octet files, uploaded unusual volumes of data, and used new user agents.
Darktrace identified every stage of this attack and immediately notified the organization’s security team via a high-priority Proactive Threat Notification. It alerted the team when the device downloaded suspicious files and when it uploaded data to a rare endpoint. If Darktrace RESPOND had been active, this malicious activity would have been blocked and neutralized in seconds.
Zoom Video Conferencing Impersonation With Phishing Link
At an inland freight water transport company in the EMEA region, Self-Learning AI caught a sophisticated Zoom impersonation phishing attack. Since the start of the pandemic, users have relied on Zoom to conduct their business remotely, and Zoom emails are constantly being sent and received.
Darktrace/Email identified subtle anomalies that revealed the email to be a sophisticated phishing attempt. The phishing link itself used a legitimate engineering company domain to bypass secure email gateways and was hidden beneath the display text: "Preview Meeting Details Here".
Taking a closer look at the encoded URI, Darktrace/Email automatically decoded the link and identified that it led to a fake Microsoft login page.
Darktrace/Email held the email back from the recipient’s inbox, preventing a credential compromise which could have been used to gather sensitive business data or send additional malicious emails from a corporate account.
Best Practices for Maritime Cybersecurity Solutions
To defend against the steps outlined in the Cyber Kill Chain, maritime organizations should consider the following best practices:
- Segmentation of Networks: Divide the network into separate segments to contain potential breaches and make lateral movements harder for attackers.
- Regular Penetration Testing: Regularly test system security to identify and address vulnerabilities before they can be exploited by attackers.
- Advanced Threat Detection: Implement systems that use artificial intelligence and machine learning to detect unusual behavior that may indicate a cyber threat.
- User Education and Awareness: Regularly train all employees on cybersecurity best practices and the latest phishing tactics.
- Incident Response Plan: Develop and regularly update an incident response plan to ensure quick action and mitigation if a breach occurs.
