automotive cyber security 2024 – What you need to know

What is automotive cyber security?

Page Contents

Automotive cybersecurity refers to the protection of automotive electronic systems, communication networks, control algorithms, software, users, and underlying data from malicious attacks, damage, unauthorized access, or manipulation. This field is crucial for ensuring the safety and security of modern vehicles, which increasingly rely on digital technologies and connectivity features.

What is the importance of Automotive Cybersecurity?

Automotive cybersecurity is essential for several reasons:

  1. Safety: The primary concern is the safety of the vehicle’s occupants. Cyber attacks can potentially take control of critical vehicle functions such as braking, steering, and acceleration, posing significant risks2.
  2. Privacy: Vehicles collect and process vast amounts of data, including personal information about the driver’s location, habits, and preferences. Protecting this data is crucial to prevent privacy breaches12.
  3. Compliance: With the increasing regulatory focus on data protection and vehicle safety, automotive manufacturers must comply with various cybersecurity standards and regulations to avoid penalties and legal issues278.
  4. Trust and Brand Reputation: Effective cybersecurity measures are vital for maintaining consumer trust and confidence in automotive brands. A single cybersecurity incident can significantly damage a company’s reputation25.

What are the key components of Automotive Cybersecurity?

Automotive cybersecurity encompasses several key components:

  • Protection of electronic systems and networks: This includes securing communication channels such as Bluetooth, Wi-Fi, and cellular networks that the vehicle uses to interact with the external world and other devices.
  • Data security: Ensuring the integrity and confidentiality of data collected and processed by the vehicle, including implementing measures to prevent unauthorized data access and theft.
  • Software security: Regular updates and patches to the vehicle’s software to protect against vulnerabilities. This also involves secure software development practices from the initial design phase through deployment and maintenance.
  • Incident response: Developing and implementing processes to quickly detect, respond to, and recover from cybersecurity incidents to minimize their impact on vehicle functionality and user safety.
  • Regulatory compliance: Adhering to international standards and regulations such as ISO/SAE 21434 and UNECE WP.29, which set guidelines for managing cybersecurity risks throughout the lifecycle of automotive products.

what are some common vulnerabilities in automotive electronic systems that can be exploited by cyber attackers?

The automotive industry faces a range of cybersecurity threats that are increasingly concerning due to the growing connectivity and complexity of vehicle systems. Here are some of the primary threats, supported by statistics and insights from recent reports:

Remote Keyless Entry Systems

Remote keyless entry systems, which allow users to unlock and start their vehicles without a physical key, can be exploited through relay attacks. Attackers capture and relay the signal from the key fob to the vehicle, tricking it into thinking the key is nearby. This vulnerability can lead to unauthorized vehicle access and theft.

In-Vehicle Infotainment Systems

In-vehicle infotainment (IVI) systems, which provide entertainment and vehicle information, can be compromised through code injection attacks or by exploiting software vulnerabilities. Attackers can gain access to the vehicle’s network, control vehicle functions, or access sensitive data stored in the system.

Electronic Control Units (ECUs)

ECUs control various vehicle functions, from engine operation to braking systems. Vulnerabilities in ECUs can be exploited to send malicious commands, potentially taking control of critical vehicle functions. This includes sending altered Controller Area Network (CAN) messages to manipulate vehicle behavior314.

Telematics and Application Servers

Telematics systems, which provide navigation, safety, and communication features, can be compromised through networked connection attacks. Vulnerabilities in telematics and application servers can allow attackers to remotely access and control vehicle functions or steal personal data.

Mobile Applications

Automotive mobile apps, used for remote control of vehicle features, can contain vulnerabilities that allow attackers to gain unauthorized access to the vehicle’s systems or the user’s personal information. Poorly secured apps can serve as entry points for cyber attackers712.

EV Charging Infrastructure

Electric Vehicle (EV) charging infrastructure can be targeted by cyber attackers to disrupt charging services or compromise the EV’s onboard systems through software exchanges during charging. This vulnerability is particularly concerning for the growing number of EVs.

Software Updates

The process of updating vehicle software can be exploited if not properly secured. Attackers can introduce malicious software through fake updates, compromising vehicle safety and functionality11.


The CAN bus, a vehicle’s internal communication network, lacks built-in security features like authentication. Attackers can exploit this to send unauthorized commands to ECUs, affecting vehicle operation. Proposals for authentication protocols aim to address this vulnerability.

Third-Party Components

Vehicles often incorporate third-party software and hardware components, which may not adhere to the same stringent security measures as automotive manufacturers. This creates potential vulnerabilities that can be exploited by attackers.

Remote Hacking and Unauthorized Access

Remote hacking is one of the most significant threats, where attackers exploit vulnerabilities in a vehicle’s software. This type of attack can lead to unauthorized control over vehicle functions such as steering, braking, and the engine. According to Upstream’s 2024 Automotive Cybersecurity Report, 95% of cyber attacks are executed remotely, and 85% of them are long-range, highlighting the prevalence and risk of remote attacks.

Data Breaches and Privacy Concerns

Connected vehicles collect and transmit vast amounts of data, including personal information about drivers’ locations, habits, and preferences. This data can be vulnerable to breaches, leading to privacy violations. The EY-Parthenon report noted that cybercrimes could harm consumer privacy, with India ranking second in 2022 for the total number of cybercrime complaints received, indicating a significant risk of data breaches in the automotive sector.

Ransomware Attacks

Ransomware attacks involve malicious software that encrypts a victim’s data, then demands a ransom to unlock it. These attacks can lock out essential operational technology systems in the automotive industry, leading to significant data and operational losses. The London Loves Tech article highlights ransomware as a prevalent threat in the auto industry, necessitating robust data backup and recovery plans.

Supply Chain Vulnerabilities

The automotive supply chain involves multiple third parties, making it susceptible to cyber threats. If any component or software from a supplier is compromised, it can jeopardize the entire vehicle system. Ensuring the security of the supply chain is crucial, as highlighted by the need for thorough security audits and strict cybersecurity guidelines in contracts with manufacturers and suppliers.

Infotainment System Exploits

Infotainment systems, which connect to the internet and other devices, can provide an entry point for hackers. These systems store personal information such as contacts and location data, attracting cybercriminals. The AT&T Cybersecurity blog lists infotainment system attacks as a top threat, emphasizing the need for strong security measures to protect these systems.

EV Charging Station Security

As the adoption of electric vehicles grows, so does the number of EV charging stations, which have become new targets for cyber attacks. Attackers may attempt to exploit these stations to gain access to private consumer information or disrupt the charging service. Upstream’s report notes that EV charging stations are a growing battleground for attacks, with regulators increasing their focus on securing these infrastructures against cyber risks.

Regulatory Compliance and Standards

The automotive industry must comply with various cybersecurity regulations and standards to mitigate risks. For example, the UNECE WP.29 regulations and ISO/SAE 21434 standard govern cybersecurity practices for vehicles and their components. Non-compliance can lead to legal and financial repercussions, as well as safety risks.
