How to Stay Safe Using Public Wi-Fi

April 30, 2025

Using public Wi-Fi at your favorite café, airport, or hotel might seem convenient, but it can expose your personal information to cybercriminals. As a credit union member, safeguarding your financial data is paramount. Here’s how you can stay secure while connected to public networks.

Understanding the Risks

Public Wi-Fi networks are often unsecured, making them attractive targets for hackers. Common threats include:

Man-in-the-Middle (MitM) Attacks: Hackers can intercept data transmitted between your device and the network, potentially capturing sensitive information like login credentials and credit card numbers.
Rogue Hotspots: Cybercriminals may set up fake Wi-Fi networks that mimic legitimate ones. Connecting to these can allow them to monitor your online activities or inject malware into your device.
Data Theft: Unencrypted websites (those without HTTPS) can expose your browsing activities and data, which hackers can capture and misuse.

Best Practices for Staying Safe

Enable Multi-Factor Authentication (MFA) – For important accounts (such as email and banking), enable multi-factor authentication. This adds an extra layer of protection, even if your password is compromised.

Avoid Sensitive Transactions – Refrain from logging into sensitive accounts or making online purchases while connected to public Wi-Fi. Wait until you’re on a trusted, secure network.

Use HTTPS Websites – Ensure the websites you visit are secure by checking that they begin with HTTPS rather than HTTP. A padlock symbol in the address bar indicates a secure connection.

Turn Off Sharing Features – Public networks make it easier for others to access your device if file-sharing or printer-sharing features are enabled. Turn these features off in your system settings while on public Wi-Fi.

Disable Auto-Connect – Most devices have an option to automatically connect to available Wi-Fi networks. Disabling this feature can prevent your device from connecting to insecure or rogue networks without your knowledge.

Keep Your Software Updated – Ensure that your operating system, browser, and security software are up to date. Software updates often contain security patches that protect against newly discovered threats.

Additional Tips

Be Cautious with Public Charging Stations: Avoid using public USB charging stations, as they can be used to install malware on your device. Instead, carry your own charger and use a standard electrical outlet.
Monitor Your Accounts Regularly: Keep an eye on your accounts for any unauthorized transactions. Early detection can prevent further unauthorized access.
Educate Yourself: Stay informed about the latest cybersecurity threats and best practices to protect your personal information.

By implementing these practices, you can significantly reduce the risks associated with using public Wi-Fi. Always prioritize your cybersecurity to protect your financial and personal information.
