There is even software available on mobile phones that will enable a VPN to start automatically when connecting to a public Wi-Fi hotspot. These public VPN services typically cost only $5-$20 per month. The traffic is secure from any local eavesdroppers on the public Wi-Fi network. When connected, all your internet traffic is sent from your computer through an encrypted tunnel to the provider’s endpoint.
This helps contribute to public Wi-Fi hotspots being more popular attack targets than some personal or private networks. Software used to eavesdrop can be easily obtained on the internet and does not require a lot of technical skills to operate. An attacker can also capture voice communication across Wi-Fi and replay it. Also, they can easily capture your email and file transfers that do not have any encryption applied. They can capture your passwords and content for sites that you sign into that do not require Secure Sockets Layer (SSL) encryption.
Many people think having this encryption secures their traffic, but they do not realize anyone who has the password can still snoop on the packets that traverse over the network.Īttackers can obtain a lot of information when eavesdropping on your Wi-Fi network connection. Many public Wi-Fi connections use Wi-Fi Protected Access 2 (WPA2), a secure protocol for encrypting traffic between the wireless AP and the client.
