Automotive Hacking: A Peril of Life!

Automotive hacking is the exploitation of vulnerabilities within the software, hardware, and communication systems of automobiles. It can potentially enable an attacker to gain unauthorized control over various vehicle functionalities, compromise safety features, or steal sensitive data by exploiting weak links in the vehicle’s security. With the increasing connectivity complexities of modern vehicles, the potential for malicious attacks has grown significantly.


The compromise in safety depends upon the amount of access gained and the intentions of the attacker. However, some of the consequences of automotive hacking can be listed as:

  • Unauthorized control of vehicle functions, such as steering, acceleration, or braking, compromises the safety of the passengers.
  • Disabling or manipulating critical safety features like airbags or anti-lock braking systems.
  • Tracking the vehicle’s location or monitoring the driver’s activities.
  • Theft of personal information stored in the vehicle’s systems, including contact lists, GPS history, or financial data.

The last few years have seen a significant advancement in vehicular technology. Automated cars/bikes have evolved to become a major part of the automobile industry. This has brought about significant ease in driving with features like automatic brakes, GPS-secured driving, and many more. However, the heavy dependence on technology has led to the development of many associated risks. It has made the vehicles vulnerable to cyber-attacks which has become a threat to safety.


Possible vulnerabilities to automotive hacking include:

  • Connected systems: Modern vehicles often have multiple electronic control units (ECUs) interconnected through a network, such as the Controller Area Network (CAN bus). These systems control various functions, including engine management, braking, steering, and entertainment.
  • Wireless systems: With the increasing integration of wireless connectivity, like Bluetooth, Wi-Fi, or cellular networks, and the adoption of infotainment systems and telematics, vehicles can become vulnerable to hacking. Weaknesses in software, inadequate security protocols, or insufficiently protected communication channels can expose vulnerabilities.
  • Inadequate authentication or authorization: Weak or poorly implemented authentication and authorization mechanisms can allow unauthorized individuals to gain access to a vehicle’s systems or control its functions. For example, if an attacker can bypass or crack the authentication mechanism used to access the vehicle’s onboard systems, they can manipulate critical functions.
  • Insecure mobile apps: Many vehicles now offer companion mobile apps that provide features like remote unlocking, vehicle status monitoring, or even remote control. Insecurely designed or poorly implemented mobile apps can become entry points for hackers to gain unauthorized access to the vehicle’s systems or extract sensitive information.
  • Insufficient physical security: Physical access to a vehicle can also present opportunities for hacking. For instance, if an attacker gains physical access to the onboard diagnostic (OBD-II) port, they may be able to connect to the vehicle’s systems and manipulate them.

How to prevent your car from being hacked?

The combination of the aforementioned vulnerabilities makes automotive systems a feasible target for hackers or cybercriminals. They use these vulnerabilities to steal personal information, disable safety features, or take control of the vehicle. While the risks in vehicular security are numerous, there are always ways to counter them. Some of the precautions that can be taken to nullify automotive hacking are:

  • Using secure software development practices: Vehicle manufacturers should use secure software development practices to design and develop their software systems. This includes using secure coding standards, performing security testing, and using secure configuration management.
  • Using secure communication protocols: Vehicle manufacturers should use secure communication protocols for their vehicles. This includes using protocols that are designed with security in mind, such as TLS and IPsec.
  • Limiting wireless connectivity: Wireless connections such as Bluetooth or wifi should be made only with secure networks. Public networks should ideally be avoided.
  • Providing regular security updates: Vehicle manufacturers should provide regular security updates for their vehicles. This will help to protect vehicles from known vulnerabilities.
  • Installing a firewall: A firewall is a network security device that monitors and controls incoming and outgoing network traffic. It can help to protect the vehicle from being hacked by blocking unauthorized communication with the vehicle’s onboard computers. An effective firewall will filter V2V (vehicle to vehicle) and V2X (vehicle to everything) communications and only allow authorized entities to communicate with the car.


In conclusion, automotive hacking without proper authorization is illegal and unethical. It is essential to respect the law, adhere to ethical guidelines, and encourage responsible and lawful behavior in the realm of cybersecurity. Car hacking not only poses a risk to the owners/passengers of the car but also to every single person present on the road. To address these risks, automakers are actively working to enhance vehicle cybersecurity, implementing measures such as secure coding practices, encryption, intrusion detection systems, and frequent software updates. However, one should keep themselves updated and aware of the risks and precautions relating to their vehicle to avoid any untoward incident.
