I wonder if it is safe to use public WiFi in places where the WiFi router might not be managed by professionals and anybody is able to come and connect to the network with their own device.
There are many things that can happen when the workplace hasn't protected their Wi-Fi. For example, DNS spoofing isn't really hard.
Let me give you a real life example:
I was at the hairdresser, my dad was first so I had to wait. I brought my laptop to work a little bit. After finishing everything, I was bored so I looked up the gateway. No problem. I guess it was just something like
192.168.1.1. It asked for a username and a password so I typed
admin, and guess what, it worked... I could've done many, many things, but instead I reported it to the owner and explained to him how to resolve this. If I didn't report this, I could've made their cash desk crash, etc. Now I'm not an evil person so I didn't do any of that but what if someone who is an evil person has the knowledge to do something like that?
I don't know what the cause is that shops, etc. are not safe enough.
When I ask 'Is it safe to use Wi-Fi at a BYOD?', I doubt if anyone will give an informative answer. It really depends on the network itself. So actually my question is:
what vulnerabilities are there when a Wi-Fi network isn't protected (good)?
