Public WiFi at coffee shops, airports, hotels, and libraries is convenient — but it is also one of the easiest attack vectors for hackers. On an unsecured network, an attacker sitting at the next table can intercept your traffic, steal your credentials, and compromise your accounts in minutes.
Evil Twin Attacks: An attacker creates a fake WiFi network with the same name as the legitimate one (e.g., "Starbucks_WiFi_Free"). You connect to it thinking it is real, and all your traffic routes through their device. Man-in-the-Middle (MITM): On shared networks, attackers position themselves between you and the access point, intercepting and potentially modifying your traffic. Packet Sniffing: Unencrypted traffic on open networks can be captured by anyone with freely available tools like Wireshark.
Passwords transmitted over unencrypted connections. Session cookies that let attackers hijack your logged-in accounts. Email content and attachments. Credit card numbers entered on HTTP sites. Your IP address and browsing history. Even encrypted HTTPS traffic leaks which domains you visit through DNS queries — test this with our DNS Leak Test.
Verify HTTPS: Only enter credentials or sensitive data on HTTPS sites. Check the padlock icon. But remember — HTTPS alone does not protect you from all MITM attacks on compromised networks.
Disable auto-connect: Prevent your device from automatically joining known networks. Attackers clone network names to trigger auto-connections.
Turn off file sharing: Disable AirDrop, network discovery, and shared folders when on public networks.
Run a Privacy Checkup to verify your connection is clean. Check your IP address to confirm it is showing correctly. Test for WebRTC leaks that may have been triggered. Review your recent account activity for any unauthorized access.
Use your mobile data instead of public WiFi when possible. If you must use public WiFi, a VPN is essential — not optional. Verify your VPN is working with our VPN detection tool every time you connect to an unfamiliar network.
