GNSS Spoofing Attacks on Cars

Disclaimer: This is for educational purposes only.

In the evolving world of automotive technology, where autonomous vehicles and smart mobility are becoming more prevalent, GNSS (Global Navigation Satellite Systems) spoofing attacks represent one of the most sophisticated threats. GNSS, which encompasses systems like GPS, Galileo, and GLONASS, provides crucial information about vehicle location, velocity, and time synchronization. In vehicles, especially autonomous and connected ones, GNSS underpins navigation, route optimization, and even safety systems like collision avoidance. However, GNSS spoofing attacks—where a malicious actor sends fake satellite signals to deceive the vehicle's receiver—pose a unique challenge. The implications are vast, from threatening personal safety to disrupting logistical operations and undermining trust in autonomous driving technologies.

GNSS Spoofing: A Closer Look

GNSS spoofing is not just a theoretical concept; it is an increasingly real and present threat. In essence, spoofing attacks involve tricking a GNSS receiver by broadcasting counterfeit satellite signals that appear legitimate but provide false location or time data. For vehicles, which rely on GNSS to navigate through space and maintain their course, the consequences of such an attack can be profound. Autonomous vehicles (AVs) and those with advanced driver assistance systems (ADAS) are particularly at risk because these systems depend on the accuracy of GNSS to function correctly.

Imagine an autonomous vehicle receiving spoofed signals that tell it it’s several meters off course. The vehicle’s systems, trusting the false data, may adjust speed, lane position, or even route based on this erroneous information. In critical situations, where a....
