Is it possible for the WiFi owner to see what I’m browsing?

Yeah that’s pretty simple as possible.

Anyway for the owner of the WiFi network, and unless WPA2-enterprise is used it is also possible for others on the same network to see what you do.

WPA2-PSK, which is used in most places, is good to decode with some technical knowledge for anyone who has the access code to the WiFi network.

Others can not only see which websites you visit: When they are websites without HTTPS, they can in theory even see which login data (including passwords) you send to log in, which pages you view exactly, they can be your cookies Intercept and thus take over your sessions etc etc…

Also e-mail (login + content) data are sent regularly (but thankfully less often) without protection and can be intercepted.

If you use the same password in multiple places, like most people, the party is for the one who can intercept your password.

With a virtual private network (VPN) you can set up an encrypted connection between two (or more) points.For example, this can be between your mobile phone on an unsafe WiFi network and your home. Or to a VPN provider that arranges it for you.

Someone who looks at it only sees the encrypted Internet traffic to and from your VPN.

That is the way the Wifi contacts the Internet.The ‘ security ‘ protocol used does not make any more. The protocol is only important for how the characters ‘ go through the air ‘.

But assume that the Wifi owner CAN do it.And when you’re not using SSL (Jeweetwel https), it may even be possible for him to log any character that you are typing.

What do you mean exactly, do you mean data or websites?Websites go through DNS, if the WiFi owner has their own DNS server, then yes. I use Pi-hole and see who visits which website. At the data level, there must be a network hub somewhere in the network, through that hub all the network traffic, via a sniffer tool, you can see all the network traffic and analize, this requires a good amount of computing power depending on the network speed, or you have to Traffic logging and later analizing. A hub passes all network traffic to all connected network cards. A network card must be promiscuous to allow traffic that is not for him/her to pass through. Normally, a network card only leaves a broadcast message or the message addressed to him/her, you need the right hardware and software to see all traffic. A network switch only forwards broadcast messages to all connected network cards and is not able to eavesdrop or it should be a smart one where you can manage others, but those are too expensive for ordinary users.

Easiest way is to look in the DNS server of the network.Most people have DNS on it automatically, and so you use the server that the WIFI owner gives you. Here you can read all the URLs nicely. In addition, there are several routers that can also do deep packet inspection. Or even tools like Wireshark etc. All this without having to hack anything or something. In short, if you’re using someone’s network, you’ve been handed over to the administrator of that network. So if you’re often on the go or so, FF sets up a VPN (with gateway routing), or a tunnel over SSH (which I use myself a lot).
