Special planning | Hackers are getting closer to your car
In the digital age, technology continues to evolve at an unprecedented pace, and with it comes both innovation and risk. One of the most pressing concerns today is the growing threat of cyberattacks on connected vehicles. While hackers or "global users" in a broader sense may not always aim to take control, their actions can range from implanting information to inserting malicious code, or even carrying out purposeless pranks. However, when it comes to targeting vehicles, there are essentially two main attack vectors: end-point attacks (directly attacking the vehicle) and network-based attacks that target external nodes, such as smart transportation systems or cloud servers.
Although cloud platforms themselves are generally secure, the communication between the vehicle and the cloud remains vulnerable. Hackers could potentially flood data channels with garbage packets, effectively creating a denial-of-service attack. Even if the cloud platform is safe, this disruption could prevent critical information from reaching the vehicle. More alarmingly, a hacker might spoof a legitimate data packet sent from the cloud, tricking the vehicle into accepting false commands. If the vehicle’s verification system has weaknesses—especially in handling remote frames or data frames—it could temporarily lose control, posing a serious risk to the entire cloud command system.
Imagine a future where the city's traffic infrastructure is fully digitized, with every road and traffic signal connected to a centralized network. In this scenario, cars would no longer rely on human drivers but instead communicate with the road itself. The road would provide real-time updates about traffic conditions, potential obstacles, and optimal routes. These data streams would be updated in milliseconds, and local decision algorithms would handle only the most immediate issues. But this reliance on connectivity also creates a major vulnerability—if the network fails, so does the entire system.
As seen in movies like *Fast & Furious 8*, hackers have already demonstrated the ability to remotely control large numbers of vehicles using systems like the “Eye of the Eyes.†Whether through physical or digital means, the cloud-based command structure offers a pathway for mass manipulation. This raises a troubling question: what happens if an attacker gains control over the entire traffic network?
In the era of manual driving, accidents were typically localized and manageable. But a full-scale network failure could lead to widespread chaos, impacting entire cities. The thought of global control over traffic systems is deeply unsettling, and we are far from being prepared for such a scenario.
Technology is a double-edged sword. We don’t reject cars because of annual traffic fatalities, just as we shouldn’t ignore the risks of the Internet of Vehicles. Although the industry is still in its early stages, security concerns are already on the agenda. Car manufacturers emphasize physical safety, but data security must also become a priority. Some believe they can manage cyber threats, while others warn that network vulnerabilities could endanger the entire system. The truth likely lies somewhere in between—but the cost of mistakes is too high to afford trial and error. As the world moves toward smarter, more connected vehicles, time is running out to get it right.
