Imagine this: After a long, exhausting day, your car drives you home. No hands on the wheel, no stress on the road. Just plain convenience and stress relief. That’s fantastic, but only if we can use autonomous vehicles without fear of them being hacked, taken over, or driven beyond our control.
Autonomous transportation is no longer a vision of the distant future. It is here, transforming the way we move people and goods. From self-driving cars cruising down city streets to drones delivering packages to your doorstep and even life-saving medical equipment, autonomous systems are becoming integral to industries and daily life.
They promise efficiency, innovation, and accessibility. However, as they become more prevalent, the pressing question remains: How do we secure these technologies from cyber threats that could undermine their immense potential?
The reliance of autonomous systems on advanced software, artificial intelligence, and interconnected networks makes them particularly vulnerable to cyberattacks. These attacks could compromise not just operational integrity but also public safety and privacy. Securing autonomous transportation is therefore not just a technical challenge, it is a necessity.
The expanding reality of autonomous transportation
The combined market for autonomous vehicles across land, air, and sea can be valued at an estimated $62 billion USD in 2022, with rapid growth projected in the coming years. As industries embrace self-driving cars, drones, and unmanned vessels, autonomous technology is poised to revolutionise transportation and redefine how we move people and goods, cementing its place at the heart of our future.
On the road, self-driving vehicles are being developed for personal use, ride-sharing, and logistics. Companies like Uber are collaborating with artificial intelligence (AI) specialists such as Nvidia to leverage advancements in AI and computing power, aiming to enhance the efficiency and scalability of autonomous systems. These efforts highlight the vital role of robust AI capabilities in enabling the next generation of transportation solutions, alongside the critical need for securing these systems against evolving cyber threats.
In the skies, drones are revolutionising delivery services, while autonomous aerial vehicles are on the horizon for passenger transport. Companies like Zipline are leading the charge, having completed over 1.3 million commercial deliveries in the US alone, primarily for medical supplies and consumer goods demonstrating how autonomous drones are transforming logistics with unparalleled speed and efficiency. Meanwhile, autonomous aerial vehicles for passenger transport are on the horizon, hinting at an even broader future for autonomous technologies in the air.
At sea, autonomous ships are beginning to navigate global waterways, promising increased efficiency in cargo transport. The Yara Birkeland, a fully electric and autonomous container ship in Norway, is already reducing emissions while demonstrating the potential of crewless maritime logistics.
While each type of autonomous system operates in its own unique environment, they all share a common reliance on connectivity, AI, and automation. These features, while enabling their functionality, also introduce vulnerabilities that hackers could exploit.

The cybersecurity challenges facing autonomous systems
The opportunities in common that they bring also come with common vulnerabilities, and these can be exploited across land, air, and sea.
Software vulnerabilities are a universal challenge. From malware injection to exploiting unpatched systems, attackers can compromise the very algorithms that drive autonomy, taking control or shutting down operations entirely. This threat is amplified by the interconnected nature of these systems, where a single breach could cascade across multiple vehicles or domains.
Another critical threat is GPS spoofing, where attackers feed false signals to disrupt navigation. This can misdirect self-driving cars, drones, or ships, potentially causing accidents, delays, or loss of valuable cargo. Sensor tampering is another shared vulnerability, as autonomous systems rely on cameras, LiDAR, radar, and other sensors to interpret their surroundings. A compromised sensor could provide inaccurate data, leading to operational errors or collisions.
Communication networks, such as Vehicle-to-Everything (V2X) or equivalent systems in other domains, are also prime targets for attackers. Spoofing, interception, or denial-of-service (DoS) attacks on these networks could disrupt coordination between vehicles and infrastructure, causing chaos and safety risks.
Additionally, all autonomous systems generate and store sensitive data, such as location histories, user preferences, and operational logs. If this data is accessed or stolen, it could lead to privacy violations, espionage, or even physical harm if attackers exploit it for targeted attacks.
It goes without saying that if these concerns remain unaddressed, it will continue to be a major challenge to build consumer trust and confidence in these systems.
Lessons from recent incidents
The urgency of addressing these cybersecurity challenges is underscored by real-world incidents.
In 2015, security researchers demonstrated the ability to remotely access and control various functions of a Tesla Model S, including the infotainment system, by exploiting software vulnerabilities. Tesla quickly addressed these issues with over-the-air (OTA) updates, but the incident highlighted the potential dangers of compromised software in connected vehicles.
GPS spoofing, a significant threat to autonomous systems, has been highlighted in several alarming cases. In 2019, Regulus Cyber successfully conducted a test on a Tesla Model 3, deceiving its navigation system through GPS spoofing. This caused the vehicle to exit a highway unexpectedly, showcasing the risks of over-the-air attacks on navigation systems. More recently, in 2024, reports of GPS spoofing incidents affecting commercial airliners have emerged, particularly in conflict zones. These attacks led to navigation systems displaying incorrect positions, posing significant risks to aviation safety. The implications are even more severe when considering unmanned vehicles, where human intervention is absent to correct the course.
These incidents make it clear that autonomous transportation systems must be designed with security as a foundational principle, not an afterthought. As reliance on autonomy grows, addressing these vulnerabilities is not just critical for the success of the technology but also for public safety and trust.
Building a secure future for autonomous transportation
Securing autonomous transportation requires a multi-faceted approach that addresses its unique risks. Communication protocols, such as V2X and drone-to-controller links, must minimally be fortified with encryption and authentication to prevent unauthorised access. AI systems used in autonomous vehicles and drones must be made resilient against adversarial attacks, such as manipulated traffic signs or false data inputs designed to mislead decision-making.
While software security plays a crucial role in protecting autonomous systems, it must be complemented by hardware-based security measures to offer comprehensive protection. Hardware security is uniquely positioned to detect and stop malicious actors attempting to access data in real time, addressing threats at the physical layer where critical data is generated and processed. For instance, embedded sensors in hardware can identify attempts to access or tamper with sensitive data and immediately lock down the system to prevent theft or corruption.
One of the most significant advantages of hardware security is its independence from interconnected systems. Unlike software, which often relies on a network of applications and updates, hardware can operate independently. This independence makes it far less susceptible to the cascading vulnerabilities that plague interconnected software systems, such as malware spreading through shared networks or dependencies on compromised third-party applications. Hardware’s self-contained nature ensures it can continue functioning and safeguarding critical data even when other layers of security are breached.
To build a robust future for autonomous transportation, redundancy and fail-safes must also be built into critical systems to ensure functionality during a breach. In the event of a vehicle hack – such as an attacker gaining remote control of a car’s steering, brakes, or acceleration – hardware security can act as the last line of defence. Its ability to operate autonomously and proactively ensures that the system can detect unauthorised actions in real-time, isolate the compromised components, and prevent malicious commands from causing harm.
For instance, in a scenario where navigation systems are hijacked or critical driving functions are manipulated, hardware-level monitoring can trigger a lockdown or revert the vehicle to a safe mode, overriding malicious inputs. This capability is particularly vital in high-stakes environments, such as urban areas or highways, where a compromised vehicle could endanger not only its passengers but also other road users.
Looking ahead to a bright and secure future
The future of autonomous transportation is bright, but its success hinges on public trust and safety. As these technologies become more prevalent, the industry must prioritise cybersecurity at every stage – from design and manufacturing to deployment and ongoing operation. A critical part of this effort is ensuring that hardware and software security work together seamlessly, creating a multi-layered defence against evolving threats.
Emerging innovations, such as edge computing to reduce reliance on centralised systems, further enhance this collaboration. By processing data closer to the source, edge computing minimises latency and the risks associated with transferring sensitive information over potentially vulnerable networks. This decentralised approach aligns well with the strengths of hardware security, which operates independently and can safeguard data at its point of origin.
Ultimately, the journey toward secure autonomous transportation requires continuous vigilance, innovation, and collaboration. By addressing cybersecurity challenges head-on, we can unlock the full potential of these technologies while safeguarding the people and systems they serve.
