Cybersecurity threats in the automotive industry are growing at an alarming rate. Autonomous vehicles are connected through vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrians (V2P).  Attackers can gain unauthorized access to critical automotive systems, manipulate vehicle behaviour, or steal sensitive user data. So, automotive cybersecurity should be a top priority for manufacturers, regulatory bodies, and consumers. Understanding the potential risks and implementing stringent measures can prevent catastrophic failure (source).

The Growing Importance of Cybersecurity in Automotive Systems

The automotive industry adopted connected vehicle technology. The connectivity improves road safety, reducing congestion, and enhancing vehicle performance. However, these advancements come with significant cybersecurity challenges (source).

Imagine a situation where your car braking to prevent a collision or navigating through the best route to prevent traffic. Now, a hacker remotely disabling those safety features or rerouting your vehicle to a dangerous location. This would be the dark side of connected vehicle technology. Unauthorized access to vehicle networks can lead to life-threatening consequences.

Key Cybersecurity Risks in the Automotive Sector

• Remote hacking – Cybercriminals can exploit vehicle’s wireless communication systems to gain unauthorized access. A hacker, sitting miles away could unlock your car, disable your brakes, and even take control of the steering system.
  
• Malware attacks – Vehicles running on outdated or unpatched software are susceptible to malware. They compromise critical functionalities like braking, acceleration, and even engine control. Suppose malicious software infects a vehicle’s system, it could lead to unexpected failures or erratic behaviour on the road.
  
• Data breaches – Modern vehicles collect vast amounts of data, including location tracking, biometric data, and personal user information. Suppose a cybercriminal gains access to this data; it could lead to identity theft, unauthorised tracking, and even financial fraud.
  
• Ransomware attacks – A cybercriminal could lock a vehicle’s software systems and demand a ransom to restore access. In some worst-case scenarios, a fleet of vehicles might be rendered useless, leading to significant disruption.
  
• Supply chain vulnerabilities – Cybercriminals exploit weak third-party software and hardware components integrated into a vehicle’s system. A minor vulnerability in a single software compromises an entire vehicle model (source).

Real-World Cybersecurity Incidents in the Automotive Industry

Cybersecurity breaches in the automotive sector are not just hypothetical threats—they are real and have already caused significant disruptions. Let’s take a look at some of the most notable incidents that have highlighted the need for stronger automotive cybersecurity measures.

• Jeep Cherokee Hack (2015) –Researchers Charlie Miller and Chris Valasek demonstrated the automotive cybersecurity breaches. It was a famous and classic cyber security breach.  They showed how they could remotely hack a Jeep Cherokee from miles away. They took control of the vehicle’s braking, acceleration, and even steering. They controlled by exploiting vulnerabilities in the Uconnect infotainment system. With this alarming demonstration, Chrysler was forced to recall 1.4 million vehicles.  They implemented software patches to close the security loophole (source).
• Tesla Model X Key Fob Hack (2020) – In another high-profile case, cybersecurity researchers showcased a vulnerability in Tesla’s keyless entry system. Hackers cloned the model-X key signal. They unlocked a model X within minutes by exploiting weaknesses in the key fob encryption. Tesla quickly responded by rolling out a security patch in the cybersecurity software. This incident showcased the vulnerabilities in keyless entry systems. There is an ongoing battle between automakers and cybercriminals (source).
• Automaker API Flaws (2022) – In 2022, researchers uncovered many vulnerabilities in automakers’ APIs. They accessed vehicle data and even controlled certain functions. These scenarios affected several well-known car brands and the widespread nature of cybersecurity risks in connected vehicles. It also raised concerns about how automakers store and manage user data. This brought the need for stricter security measures in vehicle APIs (source).

These real-world examples showcase the imminent cyber-attack on automotive vehicles.  The risks are not just theoretical but real. Automakers must take proactive steps to ensure vehicles are secure against ever-evolving cyber threats.

Essential Cybersecurity Measures for Automotive Systems

Secure Software Development and Cybersecurity Standards

Automotive manufacturers must adopt secure coding practices and conduct rigorous security testing to prevent vulnerabilities in-vehicle software. The development lifecycle should incorporate security-by-design principles, ensuring that cybersecurity is a core component from the initial stages of software creation.

Adhering to industry standards such as ISO/SAE 21434, which provides a framework for automotive cybersecurity engineering, helps manufacturers build more secure vehicles. Additionally, regulations like UNECE WP.29 enforce cybersecurity and software update management protocols, ensuring compliance and enhancing vehicle security (source).

Network Segmentation for Enhanced Cybersecurity

Modern vehicles operate using internal networks like the Controller Area Network (CAN) bus, which connects various electronic control units (ECUs). A breach in one part of the system, such as an infotainment unit, could provide attackers with access to critical safety components like steering or braking.

To mitigate this risk, manufacturers implement network segmentation, isolating safety-critical systems from less critical functions. By keeping high-risk areas separate, even if hackers access to one part of the vehicle, they cannot easily infiltrate essential driving systems (source).

Regular Software Updates and Patching

Cyber threats constantly evolve, and so should vehicle security. Over-the-air (OTA) updates allow manufacturers to remotely deploy security patches and software updates without requiring vehicle recalls. These updates can address newly discovered vulnerabilities, ensuring that vehicles remain protected against emerging threats.

OTA updates also reduce the time lag between identifying a cybersecurity risk and resolving it, which is critical in an industry where real-time protection can prevent accidents and data breaches (source).

Strong Encryption and Authentication

To protect vehicle communications and prevent unauthorized access, manufacturers must implement robust encryption techniques and multi-factor authentication (MFA). Encryption ensures that data transmitted between vehicle components remains unreadable to attackers, while MFA provides an additional layer of protection against unauthorized entry.

For instance, implementing public key infrastructure (PKI) within vehicle networks helps secure software updates, remote access functions, and user authentication, making it more difficult for cybercriminals to hijack vehicle systems (source).

Continuous Security Monitoring for Cyber Threats

Automakers and cybersecurity teams must implement real-time security monitoring to detect and mitigate threats before they escalate. AI-driven anomaly detection systems can identify irregular patterns in vehicle behaviour, alerting manufacturers to potential cyberattacks before they cause harm.

By deploying Security Operations Centers (SOCs) specifically for connected vehicles manufacturers can monitor cybersecurity threats around the clock, ensuring rapid responses to any detected vulnerabilities (source).
