Open WiFi abounds when you’re on the go, from networked buses to hotspots in train stations to the free airport internet. And no matter how secure they seem to be, treat these WiFi hotspots with care and suspicion. Many of us will use these free connections at times for convenience, yet all the same risks outlined in this article apply to any open, unverified WiFi network. Using a VPN can help protect your identity, file transfers and online activities from bad actors attempting to spy on you through the same WiFi network.

从联网巴士到火车站热点再到免费机场互联网，随时随地都可以使用开放式 WiFi。无论它们看起来多么安全，都要小心谨慎地对待这些 WiFi 热点。为了方便起见，我们中的许多人有时会使用这些免费连接，但本文中概述的所有风险都适用于任何开放、未经验证的 WiFi 网络。使用 VPN 可以帮助保护您的身份、文件传输和在线活动免受试图通过同一 WiFi 网络监视您的不良行为者的侵害。
