The Automotive Cyber Arms Race: Why OEMs & Tier 1s Need Threat Intelligence Now

Introduction 

The automotive industry is undergoing a digital revolution, with vehicles becoming increasingly connected, semi-autonomous, autonomous, and software driven. While this transformation enhances convenience, efficiency, and safety, it also exposes the automotive ecosystem to unprecedented cybersecurity threats. OEMs and Tier 1 suppliers are now facing complex challenges in securing their products against cyberattacks, and the need for Automotive Threat Intelligence has never been more critical. 

The Cybersecurity Challenges for OEMs and Tier 1 Suppliers 

1. Increased Attack Surface 

As modern vehicles integrate ECUs (Electronic Control Units), in-vehicle infotainment systems (IVI), V2X communication, and cloud services, the attack surface expands significantly. Cybercriminals can target multiple entry points, from Wi-Fi and Bluetooth to over-the-air (OTA) update systems and third-party software components. 

2. Real-World Cyber Incidents in the Automotive Industry 

Several high-profile cyberattacks have demonstrated the vulnerabilities in connected vehicles and automotive supply chains:

• Toyota Keyless Theft Exploit (2024): Toyota vehicles faced a keyless entry vulnerability, allowing thieves to bypass security systems and steal cars without the physical key. Exploiting weaknesses in CAN bus communication, attackers could trick the system into unlocking and starting the vehicle, highlighting the risks of unprotected in-vehicle networks.
• Volkswagen Data Leak Exposing EV Locations (2024): A Volkswagen Group server misconfiguration led to a data leak exposing real-time locations of EVs, affecting brands like Audi and Porsche. The breach raised serious concerns about privacy risks in connected cars, emphasizing the need for stronger data protection and access controls. 
• Kia Web Vulnerability Enabling Remote Car Tracking (2024): A security flaw in Kia’s online services allowed unauthorized access to vehicle tracking, remote unlocking, and engine control features. The vulnerability stemmed from poor authentication mechanisms, demonstrating the dangers of weak API security in connected vehicle ecosystems. 
• Honda and Nissan API Vulnerabilities (2023): Exposed APIs in connected services allowed attackers to remotely control functions like unlocking doors and starting vehicles. 

These examples highlight the urgency for proactive cybersecurity measures within the automotive industry. 

3. Regulatory Compliance Pressure 

4. Supply Chain Vulnerabilities 

The automotive industry heavily relies on third-party suppliers for software and hardware components. This dependence introduces risks such as compromised firmware, embedded malware, and supply chain attacks. Without continuous monitoring and intelligence, these vulnerabilities can remain undetected until exploited by adversaries. 

5. The Challenge of Incident Detection and Response 

Many automotive companies lack dedicated Security Operations Centers (SOCs) and Incident Response Teams (SIRTs) with expertise in embedded system threats. Traditional cybersecurity measures like firewalls and endpoint detection are insufficient against vehicle-specific attacks. This makes early threat detection and intelligence-driven defence strategies essential. 

General vs. Product-Oriented Threat Intelligence 

Why Automotive Threat Intelligence is Crucial 

Automotive Threat Intelligence (TI) provides OEMs and Tier 1 suppliers with proactive, real-time insights into emerging cyber threats. A specialized intelligence service like PCA Cyber Security’s (formerly known as PCAutomotive) TICAP platform offers significant advantages:

1. Real-Time Threat Monitoring & Attack Detection 

TICAP continuously collects and analyses intelligence on known and emerging threats targeting automotive systems. By tracking adversary tactics, techniques, and procedures (TTPs), organizations can anticipate and mitigate risks before attacks occur.

2. Proactive Risk Assessment for Supply Chains

TICAP helps monitor third-party suppliers and software components for security weaknesses, ensuring supply chain integrity. This prevents vulnerabilities from propagating through interconnected automotive systems.

3. Support for Product SIRT Teams 

4. Regulatory Compliance and Risk Mitigation

By leveraging TICAP’s intelligence, OEMs can align with ISO/SAE 21434 and UNECE R155, demonstrating proactive cybersecurity risk management during audits and regulatory assessments. 

5. Cost Savings and Business Continuity 

Cyberattacks on vehicles and infrastructure can result in product recalls, legal penalties, and reputational damage. Investing in automotive threat intelligence helps prevent costly incidents and ensures business continuity.
