The Two Big Threats of Doing Business on Public Wi-Fi

Public Wi-Fi: Convenient, but Is It
Worth the Risk to Your Business?

Public Wi-Fi is everywhere – in cafés, airports, hotels, even trains. It’s
incredibly convenient, especially for business travellers or remote
workers.

But what if connecting to free public Wi-Fi could expose your
sensitive business data to cyber criminals? That’s exactly what
happens on unsecured networks.

What's the Risk?

When you log in to public Wi-Fi, you’re potentially opening the door to scammers who exploit these networks. The two biggest threats you should know about are Man-in-the-Middle (MITM) attacks and Evil Twin attacks.

They sound like spy movie plots, but they’re real and can cause serious harm to your business.

Man-in-the-Middle (MITM) Attacks

Imagine sitting in a cafe, checking your emails or logging into your business accounts. You assume your connection is secure, but secretly a cyber criminal has intercepted your connection, becoming a hidden “man in the middle.”

They can see everything-your passwords, emails, even credit card details-and you probably won’t notice a thing. Cyber
criminals use this stolen data to:

Sell your information online.
Impersonate you in phishing scams.
Access your financial accounts, stealing funds or sensitive customer data.

Evil Twin Attacks

Imagine you’re at an airport and see two available Wi-Fi networks: “Airport Free Wi-Fi” and “Airport Wi-Fi Secure”. Both look
legitimate, but one could be an “evil twin” network set up by scammers.

Connecting to the fake network gives criminals the power to monitor your online activities. They can even:

Steal your cookies (data that remembers your login info).
Access your login credentials and personal details.
Secretly install malware on your device.

How to Stay Safe on Public Wi-Fi

Using public Wi-Fi doesn’t have to put your business at risk. Follow these tips to stay protected:

Avoid sensitive tasks (banking, payments, or accessing private data) while connected to public Wi-Fi. If it’s not something you’d feel comfortable showing a stranger, save it for a secure network.
Use HTTPS websites, which encrypt data sent between your device and the website. Look for a padlock icon or “https://” in the address bar.
Use trusted browser extensions to block malicious sites, ads, and unwanted tracking cookies.
Turn off auto-join on your devices to prevent them from automatically connecting to risky networks.
Watch out for suspicious pop-ups that might trick you into clicking harmful links. If something feels off, close it immediately.
Enable two-factor authentication (2FA) wherever possible. It adds an extra security layer, making it tougher for cyber
criminals to access your accounts.
Always keep your software updated. Regular updates patch security vulnerabilities, protecting your business devices
from emerging threats.

Is Free Wi-Fi Really Worth the Risk?

A little caution goes a long way in keeping your business safe. Next time you connect, ask yourself: “Is the convenience of
free Wi-Fi worth risking my data?” If you’d like help protecting your business data wherever you go, get in touch today.
