Yes, in theory it is possible to attack a car's in-vehicle information system through malware, causing the car to lose control while driving. Modern cars are increasingly integrating complex electronic control units (ECUs), infotainment systems, and networking functions. While these systems improve the driving experience, they also increase potential security risks. Here are a few areas to pay attention to: 1. **Network connectivity**: Many modern cars have the ability to connect to the Internet, which makes them vulnerable to cyber attacks. Once hackers successfully hack into the car, they can remotely control certain functions of the vehicle. 2. **Software vulnerabilities**: The software in the car may have unpatched vulnerabilities that hackers can exploit to attack. 3. **Physical access**: If an attacker has physical access to the vehicle, such as through the OBD-II interface, it may be easier to perform malicious operations. 4. **System integration**: Different systems in the car are often connected to each other, such as systems that control engine, brakes, steering, etc. This integration improves convenience, but it may also allow attackers to control other systems through one system. 5. **Real Case**: Past studies and some safety experiments have shown that researchers have successfully demonstrated how to manipulate vehicle functions such as braking and acceleration. Although most automakers have taken some measures to enhance safety, risks cannot be completely eliminated. In order to reduce this risk, automakers and related agencies are strengthening cybersecurity protection measures, promoting security updates and vulnerability patches. At the same time, car owners should also update vehicle software regularly to ensure the latest security patches are used.
