Keeping the Transportation Industry Moving Securely

The vast U.S. transportation industry keeps America in motion. Critical for the flow of products, services, and people between cities, regions, and across borders, transportation has traditionally relied on siloed, proprietary systems — from onboard control modules to fleet management platforms, air traffic coordination tools, and more.

In recent years, however, that has changed. The adoption of connected devices, intelligent transportation systems (ITS), and IoT sensors has transformed how organizations monitor, track, and optimize performance. These innovations have made operations faster and more efficient — but also more vulnerable.

With every new connection comes a new opportunity for cyberattacks. As the industry leverages next-generation technology, cybersecurity must remain a top priority to keep operations running smoothly and securely.

What Types of Organizations Make Up the Transportation Industry?

The U.S. transportation sector covers an enormous ecosystem of public and private entities, including:

• Ground Transportation: Public transit agencies, rideshare companies (Uber, Lyft), intercity buses, and freight carriers such as FedEx, UPS, and DHL.
• Aviation: Airlines, air cargo operators, private jets, airports, MRO companies, and air traffic control providers.
• Rail: Freight rail networks (BNSF, Union Pacific), Amtrak, commuter rail systems, and rail infrastructure providers.
• Maritime: Shipping lines (Maersk, MSC), cruise operators, port authorities, and ship maintenance companies.
• Logistics & Supply Chain: Warehouses, intermodal operators, cold chain logistics, and transportation software providers.
• Infrastructure & Support: Toll Road authorities, ITS developers, fuel logistics firms, data analytics providers, and autonomous vehicle manufacturers.

Each of these organizations — and their supporting vendors — plays a role in ensuring the safe and efficient movement of people and goods across the country.

What are the Rising Cybersecurity Risks Across Transportation?

Cyberattacks against the U.S. transportation and logistics industry are escalating. Analysts report significant increases in network reconnaissance, credential theft, and lateral movement within transportation systems compared to other sectors. Two trends explain why: the rapid digitization of fleets and traffic systems, and historic underinvestment in cybersecurity for operational technologies (OT).

According to the Transportation Security Administration (TSA) and the Department of Homeland Security (DHS), attacks targeting airlines, ports, and railways have surged in recent years — and the threat landscape continues to evolve.

What are The Top Cyber Threats Affecting the Transportation Industry?

1. Ransomware: Supply Chain and Operational Disruptions Ransomware remains the #1 threat facing U.S. transportation systems. Criminals encrypt data, disrupt operations, and demand payment for restoration — often threatening to leak sensitive cargo or passenger data. CISA warns that ransomware groups are increasingly targeting logistics and transportation networks because downtime translates directly into profit losses.

2. DDoS Attacks: Taking Down Critical Systems Distributed Denial-of-Service (DDoS) attacks flood networks with traffic, knocking critical systems offline. In transportation, that could mean grounded flights, delayed shipments, or inaccessible scheduling software. In 2023, CNN reported that a wave of DDoS attacks temporarily disabled multiple U.S. airports and state transportation websites — allegedly launched by hacktivist groups linked to geopolitical conflicts. These attacks can also act as diversions for more targeted intrusions.

3. Phishing and Social Engineering  Human error continues to be a major vulnerability. Phishing campaigns targeting dispatchers, logistics managers, or customer service agents can compromise systems with just one click. According to Cybersecurity Guide, transportation employees who manage scheduling, billing, and cargo tracking are especially at risk due to the high volume of sensitive data they handle daily.

4. Supply Chain and Vendor Exploits Every vendor in a transportation network — from software developers to maintenance contractors — represents potential entry points for cybercriminals. The Colonial Pipeline ransomware attack demonstrated how a single vendor breach can cripple national logistics systems. IT Architeks notes that third-party breaches and software vulnerabilities are among the fastest-growing risks in transportation, as attackers exploit weak vendor access controls and unpatched systems.

5. Legacy Systems and IoT Vulnerabilities Many U.S. rail, trucking, and aviation networks still depend on outdated operational technologies never designed for modern cybersecurity standards. As IoT and telematics systems connect with these legacy components, vulnerabilities multiply. Security Boulevard highlights that outdated routers, unsecured IoT devices, and unsegmented networks make it easier for attackers to move laterally through connected systems.

6. Data Breaches and Information Theft Transportation providers maintain extensive databases containing personal, financial, and operational data. CISA and the Federal Trade Commission (FTC) emphasize that stronger encryption, access controls, and data minimization practices are essential to prevent large-scale breaches and identity theft.

7. GPS Spoofing and System Manipulation GPS spoofing — falsifying satellite data to misdirect vehicles or aircraft — is a growing concern. The Federal Aviation Administration (FAA) warns that attackers can manipulate navigation systems, reroute planes or ships, or cause them to enter restricted zones. The Department of Transportation (DOT) has also identified GPS interference as a critical threat to autonomous and connected transportation systems.

Transportation: The Lifeline of American Infrastructure

The U.S. transportation industry is the backbone of national infrastructure and commerce. As CISA reminds us, “Cybersecurity is national security.” The interconnected nature of today’s digital transport systems means a single breach can disrupt entire supply chains or compromise safety on a massive scale.

Building resilience through risk-based cybersecurity, vendor oversight, and incident response preparedness is essential to protect people, assets, and goods — and to keep America moving safely.
