Why the Automotive Industry Faces Heightened Cybersecurity Risks
The UK automotive sector is undergoing a profound transformation, driven by advancements in connected cars, electric vehicles (EVs), and autonomous driving technologies. While these innovations promise efficiency and convenience, they also expose the industry to significant cybersecurity vulnerabilities. Recent data highlights a surge in cyberattacks targeting automotive businesses, underscoring the urgent need for robust defences. This blog article explores why the UK automotive industry is considered to be at higher risk of cyber breaches.
Technological Advancements and Expanded Attack Surfaces
The digitalisation of the automotive sector has revolutionised operations, but it has also created new entry points for cybercriminals. Modern vehicles are equipped with software-defined systems, Internet of Things (IoT) devices, and smart mobility features, which are increasingly interconnected. For example, EV charging stations and fleet management systems are now critical infrastructure that hackers can exploit. According to Upstream’s 2025 report, mobility-specific ransomware attacks surged by 19% in 2024 alone, with incidents targeting EV chargers and software-laden vehicles.
This shift towards connected technologies has widened the cybersecurity gap in the industry. Many organisations struggle to keep pace with evolving threats, as traditional security measures fail to address vulnerabilities in smart mobility devices. The rise of autonomous driving systems adds further complexity; remote hacking of vehicle functions such as braking or acceleration poses serious safety risks. Without comprehensive cybersecurity frameworks tailored to these innovations, the sector remains highly exposed.
High-Value Data and Intellectual Property Risks
The automotive industry is a treasure trove of sensitive data, including customer personal details, financial records, driving histories, and intellectual property such as R&D blueprints. This data is highly attractive to cybercriminals for identity theft, fraud, or competitive exploitation. For instance, ransomware attacks often aim to encrypt critical systems and demand payment for their release, causing operational downtime and financial losses.
Recent incidents illustrate the scale of these risks. In early 2025, a UK-based heavy vehicle tyre repair service fell victim to ransomware attacks that potentially exposed sensitive data. Similarly, dealerships are particularly vulnerable due to gaps in secure data transit solutions; only 9.7% of UK dealerships currently employ advanced protections for safeguarding customer information during transactions. Such vulnerabilities not only jeopardise customer trust but also threaten the competitive position of businesses in an increasingly digital marketplace.
Legacy Systems and Supply Chain Vulnerabilities
Despite rapid technological progress, many UK automotive companies continue to rely on legacy systems that lack modern security features. These outdated platforms are often incompatible with newer technologies, creating integration challenges that leave organisations open to cyber threats. Additionally, the sector’s extensive supply chain network introduces further risks; smaller suppliers with weaker cybersecurity measures are frequently targeted by attackers seeking entry points into larger manufacturers.
A notable example is a ransomware attack on a UK automotive dealership group in February 2025 that exposed customer and financial data. Such incidents highlight how supply chain vulnerabilities can ripple across the industry. When suppliers or third-party providers are compromised, it can disrupt production lines or delay deliveries, affecting partners and customers alike.
Rising Threats and Industry Trends
The frequency and sophistication of cyberattacks on the UK automotive sector are escalating. US research revealed over 100 ransomware attacks targeting the global automotive ecosystem in 2024 alone. The growing adoption of AI-driven tools by threat actors amplifies these risks; attackers use machine learning algorithms to bypass traditional defences and scale their operations.
Moreover, phishing and social engineering tactics continue to pose significant threats. Cybercriminals manipulate employees into disclosing sensitive information through deceptive emails or fake websites. These methods often lead to unauthorised access to critical systems or data breaches. As hackers become more adept at exploiting human errors alongside technological vulnerabilities, the industry’s exposure increases.
Conclusion
The UK automotive sector’s heightened vulnerability to cyber breaches stems from its rapid technological evolution, extensive data collection practices, reliance on legacy systems, and complex supply chains. Addressing these challenges requires a multi-faceted approach:
- Strengthening IT Infrastructure: Organisations must invest in robust firewalls, intrusion detection systems, and multi-factor authentication.
- Employee Training: Regular cybersecurity training can help staff recognise phishing attempts and other social engineering tactics.
- Incident Response Plans: Developing comprehensive recovery strategies ensures businesses can act swiftly in the event of an attack.
- Compliance with Regulations: Adhering to GDPR and other data protection laws safeguards customer information.
- Cyber Insurance: Policies provide financial support during recovery efforts while offering access to expert advice on handling ransomware demands.
As cyber threats evolve in scale and complexity, proactive measures are essential to protect both businesses and customers. By prioritising cybersecurity as a strategic imperative, the UK automotive industry can build resilience against future attacks while maintaining its competitive edge in a digital-first world.
