Be careful with Free WiFi

Recently I and my colleagues have visited Moscow for a business.
When we get tired we found a nice cafe (Coffee house network) with free WiFi from Beeline.
It was really nice but only for first look. We easily get internet connection, type and .. get warning that Google use self-signed ssl certificate from Beeline!
When we try point to other sites over https - we get absolutely the same message.
So,please note, that free Wifi providers start use some kind of proxies (there are a lot of them) with https monitoring features enabled (by man-in-the-middle technique).

Stay secured!
