The dangers of the connections on Wi-Fi networks depend on the confidence you have in a providers and computers on the Wi-Fi network and on the protections used.An old joke at conferences, which I visit for my work, is a presenter who shows at the end of a conference passwords that people use to read their emails. With a bit of dexterity and software like Howtodecrypt 802.11-the Wireshark Wiki , it’s not that hard to eavesdrop off low-security networks.If people connect to such a network and use unsecured protocols such as HTTP, FTP, Telnet (instead of HTTPS, SFTP, and SSH) or don’t make a VPN connection, it’s a piece of cake to read along with everything you do on the Wi-Fi network. If stronger protections are used on the network, it takes much more effort, knowledge and time to eavesdrop networks. For home-garden-kitchen use are WPA2-AES encryptions for WIFI Networks and network protocols like HTTPS, SFTP, SSH and creating VPN networks the best choices. In general, turn on Wifi only on your phone or computer in environments you’re familiar with. Open and WEP networks are unsafe, WPA2-AES are safer. For military or industrial network protections, Wi-Fi connections are rather not recommended. In the Los Alamos National Laboratory, where I worked for several years, and a real chance of spying, these networks were banned.

By being connected to a public network, the device that you are going to go to is free to anyone who sits there.If there are (virtual) holes the device that could be compromised, someone would be able to exploit it. In addition, the applications/apps you use may not be created to securely connect to the rest of the Internet.
For example, Spotify connected to the servers in the past in an unsecured way.This allowed you to eavesdrop the connection and retrieve someone’s password. Only by sitting on the same network. It’s not just to find out if an app like Spotify does or does not make a secure connection.
My little brother is this way so once his Spotify account is lost.Public Wi-Fi at the airport.
If you would like to be on a public WiFi: use VPN, make sure you have a good Firewall, make sure your device is up to date, get a good virus scanner, just do the much needed, try to use only apps that you know are only Supports secure connections.
Physically you do not run any danger, except if you are using a public city WiFi network and crossing it without first looking left and right while you are watching on your smartphone.Or if you are the type Of personality that sees every personal mistake as a reason to get depression, myocardial infarction or brain hemorrhage.
The dangers of public WiFi networks are also determined by the quality of the security that is made available on the network.It seems to be possible nowadays to prevent users from spooling the WiFi network. Unfortunately, many WiFi networks in catering establishments are not super secured despite the fact that you often have to ask for the password when ordering. The danger is that your Media Access Control (MAC) address can be copied and used to log in to other places, making it appear if you are logged in there, so the hacker can hide his identity. Another danger is that the router you log in to, if it is hacked, tries to install malware by asking you to install software to use the network. Another danger is that your network traffic is logged to be analyzed for searching for passwords or accounts to hack. Furthermore, of course, you run the danger that a hacker tries to determine who you are to infiltrate into your life so as to be able to commit deeper attacks, more toward social engineering.
I suspect that some e-mails from abroad with the request for money, are not based on a hack, but on the fixing abroad that you are there because you log into a public WiFi network, after which the scammers send your e-mail address or e-mail Program to send those phishing mails.
And so there are probably many other dangers that are not yet conceived or are not yet known when it comes to WiFi networks.The best solution is to ensure that you don’t have to log in to accounts or only work with the mobile phone network you’re using, because it works in a different way than Wi-Fi.
