In a recent study, researchers have highlighted significant cybersecurity vulnerabilities in commercial trucks and buses, which can be exploited to remotely unlock these vehicles.
This issue is particularly concerning due to the increasing reliance on software-driven systems and interconnected technologies in the automotive industry.
The study emphasizes that heavy-duty vehicles are more susceptible to cybersecurity threats compared to passenger cars due to their complex software-driven functionalities, extensive data exchange, and higher value.
Cybersecurity Risks in Heavy-Duty Vehicles
Heavy-duty vehicles, such as trucks and buses, utilize numerous electronic control units (ECUs) connected via standardized automotive networks like CAN.
These vehicles also employ various communication interfaces, including physical onboard diagnosis ports and wireless interfaces like Wi-Fi and LTE.
These features, while enhancing efficiency and connectivity, introduce vulnerabilities similar to those found in passenger vehicles.
For instance, weak remote keyless entry (RKE) systems can be exploited by thieves to unlock vehicles by jamming or manipulating signals.
Additionally, the standardized SAE J1939 protocol used in trucks can be accessed easily, allowing unauthorized manipulation of vehicle functions.
The study identifies several types of cybersecurity threats, including physical theft, electronic manipulation, data theft, and safety attacks.
Physical theft of valuable components or entire vehicles is a significant concern due to the high monetary value of these vehicles and their loads.
Electronic manipulation attacks often involve circumventing legal restrictions, such as disabling exhaust gas treatment systems or manipulating speedometers.
These actions can lead to financial losses and safety risks, especially when critical driving functionalities are compromised.
Protection Measures
According to the Report, The implications of these vulnerabilities are substantial, as they not only pose financial risks but also threaten safety and reliability.
The study underscores the need for a holistic, multi-layered protection approach to mitigate these risks.
This includes enhancing the security of communication protocols, improving component authentication, and implementing robust cybersecurity measures to protect against both internal and external threats.
Given the increasing reliance on technology in the automotive sector, addressing these vulnerabilities is crucial to ensure the safety and security of heavy-duty vehicles.
Researchers and manufacturers must collaborate to develop and implement effective cybersecurity solutions to safeguard against these emerging threats.
