You've heard of carjacking – but what about carhacking?

Carhacking: The New Threat to Smart Cars

In recent years, the automotive industry has made significant strides in incorporating advanced technologies into vehicles. These technological advancements have made cars more convenient, efficient, and comfortable. However, with the increased use of technology comes a new threat - carhacking.

Carhacking refers to the unauthorized access and manipulation of a vehicle’s computer system. Hackers can gain entry into a car’s network through various means, such as exploiting vulnerabilities in software updates, using malicious apps or websites, or even physically accessing the car’s computer through a USB port. Once inside, they can control various functions of the vehicle, including the engine, brakes, and steering wheel.

The Rise of Carhacking

Carhacking has become a growing concern in the automotive industry. According to a report by the National Highway Traffic Safety Administration (NHTSA), there were over 150 documented cases of carhacking in the United States alone between 2016 and 2018. The report also revealed that most car manufacturers had experienced some form of hacking attempt, with some brands being more vulnerable than others.

One of the most high-profile cases of carhacking occurred in 2015 when a group of researchers demonstrated their ability to remotely hack into a Jeep Cherokee’s computer system. They were able to take control of the vehicle, causing it to accelerate, steer, and even crash into a barrier. The incident prompted a recall of 1.4 million vehicles by FCA (Fiat Chrysler Automobiles), highlighting the severity of the issue.

Methods of Carhacking

Carhackers use various techniques to gain access to a vehicle’s computer system. Some of the most common methods include:

  1. Phishing attacks: Hackers send fake emails or messages that appear to be from a legitimate source, such as a car manufacturer or a dealership. The message may ask the owner to download a software update or click on a link to resolve an issue. Once the owner does so, the hacker gains access to the vehicle’s system.
  2. Malware: Hackers can install malware on a car’s computer system through a USB port or by exploiting a vulnerability in the vehicle’s software. The malware can then be used to control various functions of the vehicle.
  3. Outdated software: Many cars still run on outdated software, which can be easily exploited by hackers. Manufacturers often release updates to address these vulnerabilities, but some owners may not install them, leaving their vehicles vulnerable.
  4. Third-party apps: Some car owners use third-party apps to control their vehicle’s functions, such as starting the engine or unlocking the doors. However, these apps may have vulnerabilities that hackers can exploit to gain access to the vehicle’s system.

Consequences of Carhacking

Carhacking can have serious consequences for both car owners and manufacturers. Some of the potential risks include:

  1. Theft: Hackers can use carhacking to steal vehicles, either by taking control of the vehicle remotely or by using the compromised system to unlock the doors and start the engine.
  2. Safety risks: Carhacking can pose a significant safety risk, as hackers can take control of critical functions such as the brakes, steering wheel, and acceleration. This could lead to accidents or even fatalities.
  3. Privacy concerns: Carhacking can also raise privacy concerns, as hackers may be able to access sensitive information such as location data, travel history, and personal details.
  4. Financial losses: Car manufacturers may face financial losses due to carhacking incidents, including the cost of recalls, software updates, and potential lawsuits.

Preventing Carhacking

While carhacking is a serious concern, there are steps that car owners and manufacturers can take to prevent it. Here are some best practices:

  1. Keep your vehicle’s software up-to-date: Regularly updating your vehicle’s software will help patch vulnerabilities and reduce the risk of hacking.
  2. Use strong passwords: Choose strong, unique passwords for any apps or systems that control your vehicle. Avoid using default passwords or easy-to-guess combinations.
  3. Be cautious with third-party apps: Only use trusted third-party apps to control your vehicle’s functions, and read reviews to ensure they are safe and secure.
  4. Disable Wi-Fi and Bluetooth when not in use: Turn off Wi-Fi and Bluetooth connectivity when you’re not using them to reduce the risk of hacking.
  5. Use a VPN: Consider investing in a virtual private network (VPN) to encrypt your internet connection, making it more difficult for hackers to intercept your data.
  6. Monitor your vehicle’s systems: Regularly check your vehicle’s systems for suspicious activity or alerts that may indicate a hacking attempt.
  7. Implement security measures: Car manufacturers can implement additional security measures, such as multi-factor authentication, encryption, and secure software updates.

Conclusion

Carhacking is a growing concern in the automotive industry, with potentially serious consequences for car owners and manufacturers. However, by staying informed and taking proactive steps to protect their vehicles, owners can reduce their risk of falling victim to this type of cyber attack. Manufacturers must also prioritize security measures and regularly update software to ensure their vehicles remain safe and secure. By working together, we can prevent carhacking from becoming a major threat to our safety and privacy on the road.
