Car manufacturers regularly release software updates that address vulnerabilities in the car’s wireless systems. These updates are akin to security patches for your computer.  Treat them with the same importance and install them promptly. Procrastination can leave your car exposed to known threats.

Wireless Network Caution: 

• Discretion is Key: Public Wi-Fi hotspots are tempting, but avoid using them for in-car features like Wi-Fi hotspots themselves or app updates. Public Wi-Fi networks are often unsecured, making your car’s systems vulnerable to eavesdropping or malware attacks. Stick to secure, password-protected networks whenever possible, and treat in-car Wi-Fi hotspots with caution, only connecting trusted devices.

• Bluetooth: Encryption is Your Friend: Bluetooth is a fantastic technology, but remember, “unsecured Bluetooth” is an oxymoron when it comes to car security.  Always ensure Bluetooth connections are encrypted. This scrambles the data being transmitted, making it unreadable to anyone without the decryption key. Additionally, only pair your car’s Bluetooth with trusted devices – avoid connecting to unknown devices in parking lots or public spaces.

Password Power & Two-Factor Authentication:  

Many car’s wireless systems require accounts and passwords for features like navigation or connected services.  Here’s the golden rule: never use weak or reused passwords.  Instead, create strong, unique passwords for each in-car account.  Whenever available, enable two-factor authentication, which adds an extra layer of security by requiring a second verification step beyond just a password.

• Aftermarket Devices: Scrutinize Before You Install: The allure of aftermarket gadgets that connect wirelessly to your car is understandable. However, these devices can introduce new vulnerabilities if not chosen carefully.  Before installing any aftermarket device, research it thoroughly.  Ensure it comes from a reputable source with a good security track record.  Look for devices that prioritize security features and don’t compromise your car’s existing security measures.
