## Description

Smartphones prompt the user with sign-in notifications in the vicinity of public WiFi networks. Once the user clicks on the notification, Android automatically redirects the user to the http page served by the router to login to the network. We use this specific feature of the OS to launch a phishing attack. A NodeMCUv3/ESP8266 is used in place of the router which hosts the phishing pages.
I was able to successfully perform the attack on several older Android smartphones. It still does work with any smartphone, provided the user manually navigates to the router home IP or use any http website, which will be DNS redirected to the home IP.
The low current draw and affordability of the NodeMCUv3/ESP8266 make it an easy choice for someone to exploit such vulnerabilities by deploying several of these disposable rogue access points at public places and later access the harvested credentials from a safe distance through a backdoor.

### Usage

* Edit the HTML in the .h files as necessary, able to include GIFs, images etc as base64.
 * Configure the .ino file, make sure HTML doesn't exceed memory limit.
 * Compile and upload the code to NodeMCUv3/ESP8266 using ArduinoIDE.
