#Hacking: Wemos (ESP32) & Captive Portal using MicroPython


At the beginning of October I wrote a blog article called White Hacking: WeMos and SquirelCrawl!. I used the WeMos (ESP32) and the firmware provided by Hacker Arsenal to do a captive portal. As you known, a captive portal is a web page which is displayed to newly connected users before they are granted broader access to network resources [

This time, I've implemented the captive portal (system) using MicroPython on the ESP32. This implementation allows you to upload more than one file. This means, e.g. you can upload CSS and JavaScript files for better web page style and more interaction with the user (e.g. using jquery). However, you should not forget that the WiFi speed of the ESP32 as an access point is very limited. You should always optimize the web page!

Portal optimization is required! This is only a sample and a very beta code. The portal is far away from stable :S, but it works.

I assume no responsibility for the usage of this code and post. I repeat again, the book "The Hacker Playbook 2: Practical Guide to Penetration Testing - Peter Kim" says

Just remember, ONLY test systems on which you have written permission. Just Google the term “hacker jailed” and you will see plenty of different examples where young teens have been sentenced to years in prison for what they thought was a “fun time.” There are many free platforms where legal hacking is allowed and will help you further educate yourself.

#White Hacking: WeMos and SquirelCrawl! (update 17.10.2017)


I was surfing the web for new hacking software and hardware tools and I found the Hacker Arsenal website. This website offers "ARTILLERY FOR CYBER WARRIORS" as they said; it is basically hardware and firmware for pentester. In summary, they have actually three products especially for Wi-Fi Sniffing.

I found the Winx-Portable on the website and I thought I have something like that. I look for the boards that I've recently bought, and I find the WeMos WiFi ESP32 Development Tool. The boards are identical. Then, I tested the available firmware and they worked on my board.
