The automotive industry is rapidly evolving with the integration of the Internet of Things (IoT), transforming vehicles into sophisticated, connected machines. While this innovation brings numerous benefits, including enhanced safety, convenience, and efficiency, it also creates significant cybersecurity risks. With IoT devices embedded in vehicles and connected to external networks, these systems provide multiple entry points for cyberattacks.
At Sectech Solutions, we understand the critical need to secure IoT ecosystems in the automotive industry. In this blog, we’ll explore the latest concerns surrounding IoT vulnerabilities in connected cars, real-world examples of exploited weaknesses, and the growing risks as smart cities and transportation systems become increasingly interconnected.
The Internet of Things has revolutionised how vehicles interact with their environment, creating smarter, more connected driving experiences. Today’s vehicles often feature IoT-enabled components such as:
While these advancements significantly improve convenience and safety, they also broaden the attack surface for cybercriminals.
The more interconnected a vehicle becomes, the more vulnerable it is to cyberattacks. Each IoT device embedded in a car serves as a potential entry point for hackers. Here are some of the key IoT vulnerabilities in the automotive industry:
Connected cars often allow for remote access to features like locking/unlocking doors, starting the engine, and even controlling key systems. These access points, if not properly secured, can be exploited by hackers to gain control over the vehicle.
IoT-enabled vehicles constantly send and receive data—from GPS locations and driver behaviour to diagnostics and performance metrics. Without robust encryption, this data can be intercepted, allowing hackers to manipulate or steal sensitive information.
Many IoT devices in vehicles operate with outdated software or lack adequate security protocols. Weak authentication measures, like default passwords that are never changed, can provide easy access to cyber criminals.
The complex automotive supply chain, involving numerous third-party manufacturers and suppliers, increases the likelihood of vulnerabilities. A weakness in one part of the chain can have cascading effects across the entire vehicle system.
Over the years, several high-profile incidents have demonstrated how vulnerable connected cars can be to cyberattacks:
One of the most well-known incidents occurred when security researchers remotely hacked into a Jeep Cherokee’s infotainment system through its internet connection. They gained full control over the vehicle’s brakes, steering, and transmission—exposing the potential dangers of insecure IoT systems.
In another demonstration, researchers hacked into a Tesla Model S, taking control of the vehicle’s infotainment system and moving on to the steering, acceleration, and braking functions. Tesla responded by issuing a software update to close the vulnerability, but the incident highlighted how quickly IoT vulnerabilities can be exploited.
In this case, security flaws in the Nissan Leaf’s mobile app allowed hackers to remotely access the car’s heating and air-conditioning system and retrieve personal information about the owner’s driving habits. While it didn’t compromise safety features, it raised concerns about data privacy and security in IoT-connected vehicles.
The Integration of Smart Cities and IoT: Expanding the Attack Surface
As smart cities begin to integrate with connected vehicles, the security stakes grow even higher. With the development of smart transportation systems, vehicles are increasingly connected to urban infrastructure—such as traffic lights, road sensors, and parking systems—creating new opportunities for cybercriminals.
At Sectech Solutions, we understand the growing complexity of IoT ecosystems in the automotive industry and the increasing threats they pose. Our tailored cybersecurity solutions ensure that your connected vehicles and associated systems remain secure, even as the IoT landscape continues to evolve.
Comprehensive Vulnerability Assessments
We perform detailed vulnerability assessments to identify weaknesses in your IoT infrastructure, whether in-vehicle systems or external communication networks. By pinpointing potential entry points for cyberattacks, we help you strengthen your defences before they can be exploited.
IoT Device Security
Our team implements advanced security protocols for IoT devices embedded in vehicles, ensuring they are properly encrypted and secured. This includes patching outdated software, securing remote access points, and preventing unauthorised access to critical vehicle systems.
Network and Data Encryption
Data transmitted between connected vehicles and external networks is particularly vulnerable. We implement strong encryption protocols to protect data in transit and at rest, ensuring sensitive information—like location data and driver details—remains secure.
Supply Chain Risk Management
We work closely with manufacturers and suppliers to ensure that cybersecurity best practices are maintained across the supply chain. By addressing vulnerabilities at every level, we help mitigate risks before they reach the end vehicle.
Incident Response and Recovery
In the event of a cyberattack, quick action is essential to minimise damage. Our 24/7 incident response team ensures that any threats to your IoT ecosystem are swiftly contained, with minimal impact on your operations. We also offer post-incident recovery services to get systems back online as quickly as possible.
Conclusion: Staying Ahead of IoT Risks in Connected Cars
The automotive industry is embracing IoT technology at an incredible pace, but with this connectivity comes new cybersecurity challenges. From remote access points and data transmission vulnerabilities to the risks posed by smart city integration, connected vehicles are increasingly becoming targets for hackers.
At Sectech Solutions, we specialise in providing the advanced cybersecurity measures needed to secure connected cars and their IoT systems. Whether you’re a vehicle manufacturer, fleet operator, or supplier, we can help you navigate the complexities of securing your business against evolving cyber threats.
