So if I share someone elses mobile hotspot login for example my stepdad and family all use the same unlimited mobile xfinity hotspots plan where there are internet at millions of spots.
Could someone within the plan hack another person via the network? For example my cousin could he hack my device logged on to a hotspot or vice versa because we can see each other devices? u can see mac id of devices.
Normally no. They should not be able to gain access to your device provided that you did not mess with the firewall. As long as your firewall is up and you do not install random programs that open random ports, then your computer is safe.
For stuff that you do online, if you don't use https and just use http, then anyone can read everything you do online. They can capture your passwords and do a bunch of other stuff. Not only can people on your network do this, but also people in between you and the server such as your ISP and the server's ISP.
Well it would depend if you connect to a rogue ap. If you connect to a rogue ap there can be many bad things that could happen. Normally they would be in public as "free wifi" or something to get people on it.
But some of the more recent one's can see computer's probe for known networks and name it the same as your normal network.... scary stuff. Some sites are better then others by forcing HTTPS. But your can redirect so still scary stuff.
You really need to be more direct on what your worried about losing. Some things are much more secure then others.
*Edit read a second time anyone within wireless range can see your wireless card's mac address. But having your mac address alone is not going to do much.
