When you connect to a WI-FI network, you expose your computer and its content to the indiscretions of the network owner, but also to hackers who may take advantage of its vulnerability. This is why knowing how to spot the signs of a poorly secured Wi-Fi network is essential in order to be suspicious and take precautions.
Private WiFi and public WiFi
When you connect to a private network, it is very easy to understand whether it is properly protected. If the network is protected by a WPA2 key and the original code of the box provided by your Internet Service Provider has been changed to be replaced by a code that is sufficiently complicated (with capital letters, small letters, numbers and special characters), then you run no risk.
Public networks are not always risky as you might think. If the network has a captive portal that forces you to identify yourself, then you can be reassured. This is usually found in hotels or some public places. However, do not visit any site, as the provider can see what you are doing if they want to and you may be in trouble in some countries. These networks are generally reliable and offer a good experience.

However, if the public Wi-Fi does not ask for any code and it is not protected by a captive portal, that means that anyone can connect to it. The problem is that if someone is malicious, they can divert the use of this network and recover your data. Besides the indiscretion this represents, it can also recover sensitive data such as your bank details.
This is why it is often advisable to use a VPN when using a public network that one does not know well. The VPN will protect you and will further anonymize your connection and your route on the web. This is the best way to secure your connection, but other good reflexes can be taken.
How to protect yourself from hackers connected to WiFi ?
There are a whole host of good reflexes to keep from letting hackers use Wi-Fi against you. The first is to never connect to public Wi-Fi if you don’t really need it. If you connect to it, be sure to turn off the sharing option on your computer. This will avoid offering this easily accessible flaw to pirates.
Finally, despite all your efforts, you can still be fooled by a smarter hacker than the others. Protect your machine against intrusions and malware. A powerful antivirus is a good start, but software to scan, find and uninstall spyware is also necessary. Use it after each connection to a WIFI that seems risky.
