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.
以下是使用公共Wi-Fi熱點的一些危險的回顧;
只需簡單的工具，惡意行為者就可以從公共WIFI熱點訪問他們想要的任何資訊。以下是這些工具的工作方式;
- 中間人攻擊 （MITM） – 這是惡意行為者在連接到公共 WIFI 時發起的第一次攻擊。在MITM中，惡意行為者會在您的網路流量到達目的地之前攔截它。
- 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.
- 窺探– 窺探也稱為嗅探，是一種惡意行為者用來根據數據包捕獲您的互聯網流量並對其進行分析的技術。
- 竊聽– 這基本上是在使用者不知情的情況下監聽某個公共WIFI中發生的事情，在窺探的説明下，惡意行為者可以訪問您的消息和對話。
通過上述技術，惡意行為者可以在公共Wi-Fi網路中訪問他們想要的一切。為了安全起見，這裡有一些公共Wi-Fi注意事項;
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.
當您在公共Wi-Fi熱點時，Wi-Fi、藍牙和定位服務都應關閉。

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.
