I have been reading about the security experts recommending not to charge phones at USB stations: https://kfor.com/2019/07/02/security-experts-warn-against-wifi-cell-phone-charging-stations/

Not only that, stations providing free WiFi will be tracking users at every stop. It shows how much insecure we are. I have started accumulating some resources about WiFi security to make a complete list here: https://infosec.hatenablog.com/

Any additional resources will be appreciated. Thanks
