One day while working from a café, I connected to the free public Wi-Fi to quickly check emails and access a few accounts. It felt convenient at the moment. However, later that day I received a security alert about an unusual login attempt on one of my accounts.
That incident made me realize how risky public Wi-Fi can be if we are not careful.
Public networks in places like cafés, airports, and malls are open to many users, which makes them less secure. Attackers can sometimes monitor network traffic or even create fake Wi-Fi networks to steal information.
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. Always verify the correct Wi-Fi network name before connecting.
Since then, I always follow a few simple steps to stay safe:
- Avoid logging into banking or sensitive accounts on public networks
- Use a VPN to protect internet traffic
- Verify the correct Wi-Fi network before connecting
- Turn off automatic Wi-Fi connections
- Enable two-factor authentication for accounts
"A few small precautions can make a big difference in staying secure online."
Take control of your connection. Enable auto-connect triggers only for trusted networks, and disable file sharing when browsing outside.
