I found a suspicious wifi network at a cafe with a similar name and a login portal that tries to look legit but isn’t. How bad is it for someone who connected to it?

I let the owner know and didn’t connect.

What I wanted to know was how bad could it be for someone who did connect? What information could be exposed? 

I know passwords are encrypted for things like FB prior to being sent over the internet. Does that help stop hackers?

One issue is that yes passwords are encrypted on real sites, but this fake network could have local fake versions of things like amazon,facebook etc. 

When you log onto this network and log into those sites everything may seem fine but theyve just got your username and password because you have been redirected to their identical looking version of those sites which can capture your inputs.
