Every day, millions of French people connect to public Wi-Fi in cafés, airports, hotels, and train stations. What most don't realize: these connections are often vulnerable to cyberattacks.

The most common attacks on public Wi-Fi

1. Man-in-the-Middle (MitM)

An attacker positions themselves between you and the Wi-Fi access point to intercept your traffic. Passwords, banking data, emails... everything can potentially pass before their eyes if the connection isn't protected.

2. Evil Twin (fake access point)

Attackers create a Wi-Fi network that mimics a public venue's network ("CafeParis_Free") to trick users. Once connected, traffic passes through their infrastructure.

3. Packet Sniffing

Tools exist that can analyze data packets traveling over a network. Without encryption (HTTPS or a VPN), data travels unencrypted and can be read by a third party on the same network.

How a VPN protects you

PureVPN creates an AES-256-bit encrypted tunnel that makes your data unreadable to anyone else on the same network. Even if a third party intercepts your packets, they cannot decrypt them.

Protection provided:

  • Encryption of all incoming/outgoing traffic
  • Protection against DNS leaks
  • Kill Switch in case the VPN disconnects
  • Alert when connecting to an unsecured network

Enabling public Wi-Fi protection with PureVPN

  1. Install PureVPN on your device
  2. Enable "Wi-Fi Security" mode in the settings
  3. Enable automatic connection on unsecured networks
  4. Enable the Kill Switch

Conclusion

Avoid connecting to public Wi-Fi without protection. A VPN like PureVPN encrypts your traffic seamlessly across all your devices.
