Cybersecurity isn’t just about protecting your computer or smartphone. Your car is now a target, too. Modern vehicles are essentially computers on wheels, loaded with smart technology—from keyless entry and infotainment systems to GPS tracking and remote start functions. But as cars become more connected, they also become more vulnerable to cyber threats.
How Can a Car Be Hacked?
Cybercriminals have found multiple ways to compromise vehicle systems, sometimes without the driver even realising it. Here are some of the most common attack methods:
- Key Fob Cloning: Thieves can intercept signals from your key fob, allowing them to unlock and even start your car without ever touching it.
- Malware Attacks: If you connect an infected USB device or download malicious software via your car’s Wi-Fi, hackers can gain access to sensitive systems.
- GPS and Data Theft: Many vehicles store personal data, including locations, contacts, and even Wi-Fi credentials. If accessed, this information could be exploited.
- Remote Control Exploits: Some high-profile cases have demonstrated how hackers can remotely take control of critical vehicle functions, including braking, acceleration, and steering.
- Ransomware for Cars: This emerging threat could see cybercriminals locking you out of your own car and demanding payment to regain access.
How to Protect Your Car from Cyber Threats
Although automotive cybersecurity is still evolving, there are practical steps you can take to minimise risks:
- Keep Your Car’s Software Updated: Manufacturers frequently release security patches, just like for your phone or laptop. Check for updates regularly.
- Disable Unnecessary Connectivity Features: If you don’t use Wi-Fi, Bluetooth, or remote access, consider turning them off.
- Use a Signal-Blocking Pouch for Your Key Fob: This prevents criminals from cloning your key’s signal.
- Be Cautious When Connecting Devices: Avoid plugging in unknown USB drives or connecting to untrusted networks.
- Monitor for Unusual Activity: If your car’s systems behave strangely—such as unlocking unexpectedly or displaying errors—it could be a sign of tampering.
As vehicles become smarter, so do the cyber risks they face. Ensuring your car’s security is just as important as locking your doors at night. Are you confident your car is protected?
