What Is Car Hacking, and How Can It Be Prevented?

Car hacking means unauthorized access to a vehicle’s digital systems. Modern cars are no longer just mechanical machines with engines, brakes, and wheels. They are connected computers on wheels, often using software, sensors, wireless connections, mobile apps, Bluetooth, GPS, and electronic control units to manage everything from entertainment to safety features.

That does not mean every connected car is about to be hijacked. But it does mean vehicles now have cybersecurity risks that older cars did not face. The U.S. National Highway Traffic Safety Administration says cybersecurity in modern vehicles is tied to safety because attacks could target electronic systems, networks, software, data, and communication links. The real solution is not panic; it is better design from manufacturers and smarter habits from drivers.
