As vehicles become increasingly connected, integrating sensors, software, and internet connectivity, they offer enhanced safety and convenience features. However, this technological advancement also exposes them to significant cybersecurity risks, making them susceptible to hacking and unauthorized access.
A notable example occurred in 2024 when researchers, including Sam Curry, identified a vulnerability in Kia’s web portal. This flaw allowed unauthorized reassignment of control over internet-connected features in Kia vehicles manufactured after 2013. Similarly, certain Subaru models were found to be remotely hijackable and trackable due to security weaknesses.
The financial impact of such cyberattacks on the automotive industry is substantial. According to a report by VicOne, the industry faced approximately $22.5 billion in cyberattack costs, including $20 billion from data breaches, $1.9 billion due to system downtime, and $538 million in ransomware damages.
Modern vehicles are vulnerable to various cybersecurity threats, including remote hacks through Bluetooth, Wi-Fi, and cellular connections; physical access attacks via diagnostic ports like OBD-II; software vulnerabilities that can be exploited for unauthorized control or data theft; and malware or ransomware injections that can incapacitate vehicle systems.
In-vehicle networks such as the Controller Area Network (CAN) and Local Interconnect Network (LIN), which manage critical functions from engine control to seat adjustments, were not originally designed with security in mind. This oversight leaves them particularly susceptible to hacking. Implementing measures like encryption, authentication, and intrusion detection systems is essential to safeguard these networks.
The advent of autonomous vehicles introduces additional security concerns. Self-driving cars rely heavily on AI algorithms and sensor systems, necessitating robust cybersecurity measures to protect against both external and internal threats. Ensuring the integrity of communication between these components is critical for the safety of passengers and the public.
Manufacturers and regulators must prioritize cybersecurity in vehicle design and operation. This includes conducting thorough risk assessments, implementing comprehensive security protocols, and staying vigilant against emerging threats to protect consumers and maintain trust in automotive technologies.
