Special planning | Hackers are getting closer to your car
In the modern era of connected vehicles, the threat landscape is evolving rapidly. Hackers—often referred to as "global users" in a broader sense—are not always aiming to take full control. Sometimes, their goal is simply to inject information or insert malicious code, and in some cases, it could even be a harmless prank. However, when it comes to targeting vehicles, there are essentially two main approaches: end-target attacks (directly attacking the vehicle itself) and pan-net attacks, which involve external network nodes, intelligent transportation systems, and cloud servers.
While the latter is still in early development stages, the potential attack methods are often based on existing network vulnerabilities. For example, hackers have already attempted to flood data channels with garbage packets, effectively carrying out a disguised denial-of-service attack. Although cloud platforms themselves may be secure, communication between the vehicle and the cloud can be disrupted. In such scenarios, a hacker might impersonate the cloud by sending a "studded" data packet to the vehicle. If the vehicle's system has weaknesses in verifying remote frames or data frames, it could temporarily lose control, posing a serious risk to the entire cloud command infrastructure.
Imagine a future where the city’s road network is fully digitized, with every inch of road and traffic facility generating real-time data. Vehicles would no longer rely on human drivers but instead communicate with the road itself. The road would inform the car about upcoming obstacles, suggest optimal routes, and even guide it through complex situations. These data streams are updated in sub-millisecond intervals, and local decision-making algorithms are designed to handle simple scenarios without exhausting all possible conditions. However, this reliance on the network introduces a new kind of vulnerability—when everything depends on connectivity, a single point of failure could lead to widespread chaos.
As depicted in *Fast & Furious 8*, hackers have demonstrated the ability to "bulk" thousands of vehicles using systems like the "Eye of the Eyes." No matter how technically implemented, the cloud-based command mechanism inherently allows for the mass production of "zombie" vehicles. In the age of manual driving, traffic accidents were usually localized and manageable. But if an entire city’s network were to go offline, the consequences could be catastrophic. We cannot afford to face a situation where the entire traffic system is under global control.
Technology has always been a double-edged sword. We don’t stop using cars just because of annual road fatalities, and similarly, we shouldn’t abandon the Internet of Vehicles due to security concerns. While the industry is still in its early stages, security issues are already being addressed. Car manufacturers are focusing on physical safety, but data security will become equally critical in the future. Some believe they can handle even mock attacks, while tech companies argue that vehicle network security risks could threaten the entire system. Neither side is entirely right, but the cost of mistakes is too high, and time is running out.
