Auto advice: Can a car really be hacked? Car software can be hacked like any computer - however carmakers invest heavily in security Is it true that my car can be hacked? Yes. From engine management to drive assistance and even lighting, software governs many core functions, so it can be hacked in pretty much the same way as anything else that is computer-based.

Hackers generally gain access within the car’s ecosystem through things like your mobile app, Bluetooth or Wi‑Fi, and keyless entry system. They simply exploit weaknesses in the vehicle software or in the cloud services that communicate with the car.

If a car is hacked, attackers might unlock the doors, start or stop the engine, track a car’s location or access personal data linked to the car’s online account.

Using only a license plate number, they were able to remotely control millions of cars; they could geolocate the cars in real time, lock or unlock the doors, start or stop the engine and trigger the horn. Research has shown that it is theoretically possible to remotely interfere and take over control of functions like braking or steering in some cars. However, these scenarios are complex, highly controlled and to date have been confined to demonstrations of what’s possible rather than criminal use. Read more What are the key concerns about
