Each time you connect to a public Wi-Fi hotspot, you increase your chances of being exploited by malicious actors. Whether it’s secure public Wi-Fi, the risks are the same. But with so many and so fast public Wi-Fi hotspots around, there’s no way of getting to the internet without trying one. In this situation, you ought to use the best cyber practices and various security and privacy mechanisms to ensure your internet traffic and data is safe.
下面简要介绍使用公共 Wi-Fi 热点的一些危险；
只需简单的工具，恶意行为者就能从公共 WIFI 热点获取他们想要的任何信息。以下是这些工具的工作原理；
- 中间人攻击（MITM）-- 这是恶意行为者连接到公共 WIFI 时发起的第一种攻击。在 MITM 中，恶意行为者会在你的网络流量到达目的地之前截获它。
- Spoofing – This is a technique of masquerading or imitating a legitimate entity. For instance, after a MITM attack, a malicious actor can impersonate the receiver and send messages back to you. Malicious actors can even launch a complicated attack; website spoofing. Unsuspecting users will log into/access the website thinking it’s the legitimate one.
- 窥探--窥探又称嗅探，是恶意行为者用来捕获互联网流量数据包并进行分析的一种技术。
- 窃听-基本上就是在用户不知情的情况下窃听某个公共 WIFI 上发生的事情，在窥探的帮助下，恶意行为者可以获取你的信息和对话。
利用上述技术，恶意行为者可以访问公共 Wi-Fi 网络中他们想要的一切。为了安全起见，以下是公共 Wi-Fi 的一些注意事项；
不要 use public Wi-Fi to access any of your sensitive or confidential data. This usually involves your bank detail and any accounts that contain your personally identifiable information. Malicious actors are usually on alerts when you access certain information or websites. Your information can be used to blackmail you and propagate further attacks such as identity theft and fraud.
不要 use public Wi-Fi to do your online shopping. This is because purchases are involved which translate to your debit or credit card which further translates to your bank. Even if you have a separate shopping account with every cybersecurity detail taken care of, shopping online using public Wi-Fi isn’t the best practice as you risk everything, including your home address.
Don’t leave your devices unattended even if you’re in a secure public Wi-Fi hotspot. If you really have to, ensure its password-protected, and you have locked it. Malicious people can take a sneak peek of what you are doing or even take the opportunity to install malware on your device. Others might even steal your device, and you might end up losing all your data in case you don’t have any backup.
Do turn off automatic Wi-Fi scanning, connectivity, and adaptive Wi-Fi settings. Most devices offer this feature for your convenience but again they might be an open doorway for cybercriminals to access your data. Turn off your WIFI completely when not using Wi-Fi in public Wi-Fi hotspots. Hackers can secretly capture your devices automatic scanning requests and use them to wreak havoc.
做 turn off Bluetooth connectivity. Besides, Wi-Fi, your Bluetooth connectivity can also pose a greater risk. Only use it in your home where you need to communicate with other smart devices. In public Wi-Fi hotspot, you definitely don’t need it. Similar to Wi-Fi, malicious actors can intercept your Bluetooth request and gain access to your device.
在公共 Wi-Fi 热点时，应关闭 Wi-Fi、蓝牙和定位服务。

If you urgently need to use public Wi-Fi in any way, connect to a VPN first. A VPN will protect you against all public Wi-Fi vulnerabilities by encrypting your entire internet traffic using un-hackable encrypting standards. This encryption ensures that prying eyes and various malicious actors won’t get access to your internet traffic. Also, a VPN gives you anonymity as it assigns you a virtual private address that masks your actual IP address.
