As cars become more connected and equipped with GPS, Wi-Fi, Bluetooth, and even the internet, the risk of car hacking has become a real concern for drivers.

Car hacking may sound like something out of a sci-fi movie, but it’s a growing issue that Canadian drivers must understand.

Here’s a guide on car hacking, its risks, and how to protect your vehicle from cyber threats.

What Is Car Hacking

Car hacking refers to the unauthorized access or manipulation of a vehicle’s electronic systems.

Modern vehicles have up to 100 computers and electronic control units (ECUs), which control everything from steering and brakes to engine performance.

Hackers can gain access to these systems to tamper with your car’s functions, lock or unlock doors, and even compromise safety features.

Why Car Hacking Is A Growing Concern

As more cars connect to the internet, they create multiple entry points for hackers.

A study by McAfee found that more than half of new cars are vulnerable to cyber attacks, with the risk increasing as manufacturers add more connectivity features.

While no system is 100% secure, understanding the risks helps drivers take proactive steps.

How Hackers Access Vehicles

Hackers can use several methods to access a vehicle’s systems:

  • Through Connected Apps: Many modern cars connect to mobile apps that allow you to start the engine, check fuel levels, or track location. If these apps aren’t properly secured, they can provide a backdoor for hackers.
  • Bluetooth and Wi-Fi Vulnerabilities: Wireless technology like Bluetooth and Wi-Fi is common in cars for convenience, but it can also expose vehicles to unauthorized access.
  • Physical Access: Hackers with physical access to your car can plug into the OBD-II port to gain control of the vehicle’s systems.

Protect Your Car By Updating Software

One of the simplest ways to keep your car safe from cyber threats is by updating its software.

Manufacturers release updates that patch security vulnerabilities.

If your car has a telematics system or a dealer-provided app, check for updates regularly and install them as soon as they’re available.

Use Strong Passwords And Avoid Sharing Logins

If you use an app to control or monitor your car, ensure it’s protected with a strong, unique password.

Avoid sharing login information with others, and enable two-factor authentication if available.

Weak or shared passwords are one of the easiest ways for hackers to gain unauthorized access.

Limit The Use Of Public Wi-Fi Networks

Public Wi-Fi is convenient but often less secure, making it easier for hackers to intercept data.

Avoid connecting your car to public networks.

Instead, use a secure home Wi-Fi network for software updates or telematics services or a personal hotspot if you need internet access on the road.

Disable Unnecessary Features

If you’re not using features like Bluetooth or Wi-Fi, consider turning them off.

This limits potential entry points for hackers and reduces the likelihood of unauthorized access.

Likewise, you can disable keyless entry systems if they aren’t essential, as these can be manipulated to unlock vehicles.

Consider Cybersecurity Insurance

Cybersecurity insurance for cars is a new but growing field.

Some insurance companies now offer policies that cover the cost of cyber-attack repairs.

While not necessary, it’s worth exploring for peace of mind, particularly if your car has many internet-connected features.

Stay Informed About Car Hacking Trends

Car hacking is constantly evolving, and staying informed is essential.

Follow news updates from automakers, and consider consulting your dealership about the security features of your vehicle.

Being aware of potential threats allows you to take steps to protect your car.

Car hacking is a growing concern, but with proactive steps, you can protect your vehicle from cyber threats.

Understanding your car’s technology and being cautious with connected features can help ensure your vehicle and data remain safe.
