Analysts warn over-the-air vehicle tech raises cybersecurity concerns

Analysts say the growing use of overtheair software updates in vehicles is increasing cybersecurity risks for automakers and transportation systems. The technology allows cars, buses, and other connected machines to receive software, firmware, and data remotely, making updates faster and cheaper than traditional recalls. The article notes that Tesla helped popularize overtheair updates in 2012, and the approach is now widely used across the auto industry. But experts warn that the same connectivity can create weak points that may be exploited by attackers, including possible risks to vehicle controls, battery systems, and other critical functions. Concerns intensified after tests by Norwegian bus operator Ruter found potential vulnerabilities in one of its electric buses. The issue has since prompted scrutiny in the U.K. and Denmark, while analysts say the broader challenge extends beyond one company or country. They argue that regulators and manufacturers may need stronger security checks and clearer oversight as the technology spreads to rail, maritime, drones, industrial machinery, and robotics.
