You love your car’s technology—keyless entry, GPS navigation, smartphone connectivity, and even self-driving features. But while these make driving easier, they also open the door to cyber threats. Just like your computer or phone, your car can be hacked, putting your personal data and even your safety at risk. So how can you stay one step ahead of cybercriminals? Here’s what you need to know to keep your car’s technology secure.
Understanding Your Car’s Vulnerabilities
One of the main entry points for cyber-attacks is the car’s infotainment or navigation system, which connects to the internet and often stores personal data such as contacts, locations, and music preferences. Additionally, many newer vehicles come equipped with Wi-Fi hotspots, allowing multiple devices to connect. While convenient, these features can also be exploited if not properly secured. To reduce risk, limit connections to trusted devices only and review your list of connected devices regularly. Be cautious when using third-party apps and services for navigation, entertainment, or remote control, as they can introduce vulnerabilities.
Beyond infotainment, various vehicle systems are also connected to the internet, including mileage tracking, tire pressure monitoring, fuel usage, braking data, and engine diagnostics. While this connectivity is helpful, it can also be a target for hackers. Check with your car dealer about the cybersecurity measures in place to protect your vehicle’s systems.
Protecting Your Key Fob
Your key fob, which grants access to your car, can be an easy target for hackers. Criminals use electronic signal amplifiers to intercept your fob’s signal, sometimes from up to 100 feet away, potentially unlocking and even starting your car without your knowledge. To prevent this:
- Store your key fob in a metal box or an RFID-blocking pouch to prevent signal interception.
- Some key fobs allow you to disable the wireless signal manually—check your vehicle manual to see if this feature is available.
- Wrapping your fob in aluminum foil can also help block signals in a pinch.
- Manually locking your doors is an extra safeguard, as some thieves use signal jammers to make you think your car is locked when it isn’t.
Keep Your Car’s Software Up to Date
Software updates are crucial for fixing security vulnerabilities. Cybercriminals often exploit outdated software to gain access to a vehicle’s systems. To protect yourself:
- Bring your car to the dealer for routine software updates.
- Check your manufacturer’s official website for downloadable updates.
- Stay in contact with your car manufacturer to receive notifications about recalls.
- Check gov for any relevant recalls affecting your vehicle.
Be Wary of Mechanics and Counterfeit Parts
Your mechanic has access to your car’s onboard diagnostics, which contain valuable data. While most mechanics are trustworthy, some may use this access to replicate keys and steal vehicles. Additionally, counterfeit parts pose not only cybersecurity risks but also physical safety concerns. Always ensure that you’re getting certified parts and working with reputable mechanics.
Be Cautious with Your OBD-II Port
The OBD-II port is a diagnostic access point that allows mechanics to check engine performance and retrieve vehicle data. However, leaving devices plugged into this port, such as insurance tracking devices, can make your car more vulnerable to cyberattacks. If you don’t need a device plugged in, remove it to reduce risk.
Extra Layers of Security
You can take simple steps to make it harder for a hacker to access your vehicle.
- Invest in a steering wheel lock. Even if a hacker gains electronic access to your car, they won’t be able to drive away with a physical lock in place.
- Turn off Bluetooth when not in use. If you’re not actively using Bluetooth, disable it to prevent hackers from getting to your phone or vehicle data.
- Secure your Wi-Fi password. If your car has Wi-Fi-enabled remote features, change the default password and enable two-factor authentication if possible. Never leave your password written down in your car and make sure to regularly update it.
- Disable remote systems when not needed. Features that allow remote unlocking, starting, or tracking should be turned off when not in use to minimize potential entry points for hackers.
Avoid Phishing Scams
Cybercriminals often use phishing tactics to gain access to vehicles. They may send fake emails with malicious links or attachments that install malware on your car’s system. Since cars lack built-in malware protection, these infections can be hard to detect. Protect yourself by:
- Never opening emails from unknown sources.
- Avoiding clicking on suspicious links.
- Verifying messages from your car manufacturer before taking any action.
Watch for Suspicious Activity
If you notice unusual behavior in your vehicle, such as unexpected setting changes, new sounds, or erratic electronic functions, it could be a sign of hacking. If anything seems off, contact your dealer or manufacturer immediately to investigate potential breaches.
By staying vigilant and following these cybersecurity measures, you can enjoy your car’s advanced technology while keeping it safe from hackers.
