The transport industry plays a vital role in economic growth and social well-being by facilitating the mobility of people and the flow of goods. It is also a pillar of business competitiveness. However, its heavy reliance on information technology makes it particularly vulnerable to cyber-security risks. With the advent of connected systems and their increasing interconnection, the doors are wide open to cyber-attacks. This phenomenon threatens not only to disrupt traffic but also to compromise sensitive data and jeopardise the safety of users.
This guide highlights the five main vulnerabilities in the transport industry and shows how the use of pentesting (or penetration testing) can play a decisive role in detecting and preventing these vulnerabilities. Pentesting, a security auditing process that simulates attacks to identify and fix vulnerabilities, is proving to be a major asset in improving the security of transport infrastructures and protecting them against cyber threats.
Interaction with information technology and cyber security
The transport industry is increasingly relying on information technology (IT) to strengthen its processes, improve performance and offer new services. However, this growing reliance on IT also raises critical cyber security issues. Transport systems are increasingly being targeted by sophisticated and frequent cyber attacks. This article looks at three fundamental aspects of the interaction between IT and cybersecurity in the transport sector: the management of network connections and remote access, the interdependence of IT and operational systems, and the protection of critical data and monitoring information.
Network Connections and Remote Access
Modern transportation systems are interconnected, not only with each other but also with external entities such as suppliers, partners, authorities, and customers. These connections enable information exchange, remote equipment control, and innovative services such as e-ticketing, carpooling, and shared mobility. However, these same connections increase transportation systems' vulnerability to cyberattacks, as hackers can exploit them to access sensitive data or take control of systems. Notable incidents, such as the 2015 Jeep Cherokee hack and the 2016 cyberattack on San Francisco’s public transit network, highlight the urgent need to strengthen network security and remote access. Implementing encryption protocols, firewalls, authentication systems, and VPNs is crucial to mitigating these risks.
Interdependence of IT and Operational Systems
Transportation systems primarily consist of two categories: IT systems, which manage data, communications, and applications, and operational systems, which oversee infrastructure, vehicles, and equipment. The growing interaction between these two types of systems is essential for efficient operations and service optimization. For instance, IT systems can send instructions to regulate traffic or trigger alerts. However, this interdependence also increases security risks, as demonstrated by the 2017 NotPetya ransomware attack, which severely disrupted major transportation companies. Such incidents highlight the importance of protecting both IT and operational systems through detection, prevention, and incident response tools.
Security of Critical Data and Traceability Information
The data generated and processed by transportation systems are essential for their operations, performance, and competitiveness. These datasets—related to infrastructure, vehicles, passengers, or financial information—are often sensitive and require strong protection against cyberattacks aiming to steal, alter, or expose them. The 2018 Cathay Pacific breach, in which the personal data of millions of passengers were compromised, and the 2019 cyberattack on MSC shipping company underscore the urgency of securing critical data and traceability information. Implementing encryption, backups, access controls, and compliance measures is vital to ensuring the safety of these assets.
Main vulnerabilities in the transportation industry
Cybersecurity is essential in the transportation sector to protect systems from various threats. This article explores five main vulnerabilities: weaknesses in embedded operating systems, lack of updates and maintenance, identity and access management flaws, communication protocol weaknesses, and exposure to DoS/DDoS attacks. Discover how penetration testing (pentesting) can help identify and fix these vulnerabilities.
Weaknesses in embedded operation systems
Embedded operating systems control critical functions in transportation electronics, such as radars and onboard computers. While designed for efficiency, their security is not always guaranteed, making them susceptible to cyberattacks. A striking example is the 2019 vulnerability discovered in VxWorks, affecting over 200 million devices. Pentesting plays a crucial role in testing and strengthening the security of these systems.
Lack of updates and maintenance
Various transportation system components often suffer from insufficient updates and maintenance, making them vulnerable to cyber threats. The 2017 WannaCry ransomware attack on Deutsche Bahn highlights the importance of regular system maintenance. Pentesting can assess security levels and recommend corrective measures to prevent such vulnerabilities.
Identity and access management flaws
Identity and access management is critical for ensuring data confidentiality and integrity in transportation systems. Weaknesses, such as poor password security, can open the door to cyberattacks, as seen in the 2018 British Airways breach. Pentesting is essential for testing access policies and preventing these vulnerabilities.
Communication protocol weaknesses
Communication protocols define how information is exchanged within transportation systems. However, outdated or misconfigured protocols can compromise security. The 2016 discovery of a flaw in the ADS-B protocol highlights the risks of interference. Pentesting helps identify and correct these flaws to ensure secure communication.
Exposure to Denial of Services (DoS) and Distributed Denial of Services ( DDoS)
DoS and DDoS attacks pose a significant threat to transportation systems by overwhelming them with malicious traffic, rendering them inoperable or malfunctioning. These attacks can lead to reduced transportation capacity, degraded service quality, or even compromised passenger safety. A notable case in 2020 involved a DDoS attack targeting SNCF’s online booking system, generating a surge of 200,000 requests per second, preventing customers from booking or modifying tickets for several hours. This incident underscores the critical need to defend against such attacks in the transportation sector. Conducting penetration testing helps assess system resilience, identify vulnerabilities, and develop effective mitigation strategies.
Implications and consequences of cybersecurity vulnerabilities in the transportation industry
We previously explored the vulnerability of transportation systems to cyberattacks and how penetration testing (pentesting) can enhance their security. Here, we will discuss the implications and consequences of these vulnerabilities in the transportation sector. In particular, we will examine how they affect operational security and transport safety, leading to economic repercussions and financial losses, as well as issues related to the protection of personal and sensitive data.
Impact on Operational Security and Transport Safety
Cyberattacks pose a direct threat to the security and safety of transportation systems, compromising their proper functioning and potentially causing dangerous incidents. For example, in 2018, Deutsche Bahn fell victim to an attack by the Emotet malware, which allowed remote control of critical elements such as switches and signals. This attack resulted in significant delays, cancellations, and even collisions, causing multiple injuries. These incidents highlight the crucial importance of penetration testing to detect and fix vulnerabilities that could impact the availability, reliability, and resilience of transportation systems.
Economic Repercussions and Financial Losses
The transportation sector also suffers significant economic consequences due to cyberattacks. These attacks can severely impact companies' competitiveness, leading to both direct costs (repairs, revenue losses) and indirect costs (customer loss, reputational damage). A striking example is the 2017 attack on EasyJet’s booking system by the Magecart malware, which cost the company over €200 million in fines, compensations, and loss of customer trust. These examples illustrate the urgency of securing transport companies' operations through penetration testing to better understand and mitigate the financial risks associated with security breaches.
Challenges in Protecting Personal and Sensitive Data
Finally, protecting personal and sensitive data is another major concern. Cyberattacks threaten the confidentiality and integrity of this data, potentially leading to privacy breaches, fraud, or identity theft. A notable example is the 2020 attack on the RATP’s personal data system, carried out using the Ryuk ransomware, exposing the information of over 12 million users. This underscores the importance of conducting pentests to ensure that transportation systems comply with security and data protection standards, guaranteeing privacy and regulatory compliance.
