We all love public Wi-Fi—it’s free and available in coffee shops, hotels, and airports. One afternoon, I was working at a local cafe and connected to their public network to check some files and check my social media. Everything seemed fine, until I got a notification about an unusual login attempt on my account.
I disconnected immediately. It turned out someone else on the same network was trying to access my connection. This is a common threat on public networks called a "Man-in-the-Middle" (MitM) attack, where someone intercepts your data.
Man-in-the-Middle (MitM) Threat
Without encryption, routers transmit data packets in plaintext. Threat actors can sniff this traffic to capture your session cookies, login credentials, and personal chats.
That experience made me realize how unsafe public Wi-Fi can be. Free networks are convenient, but we must protect our personal data first.
To stay safe, we should avoid checking sensitive information like banking details or corporate logs on public networks. Using a VPN is also a great way to encrypt your data. If you don’t have a VPN, it is safer to use your mobile data.
"Encryption is not a choice, it is a basic shield for your mobile data."
Take control of your connection. Enable auto-connect triggers only for trusted networks, and disable file sharing when browsing outside.
