ESP32Marauder

ESP32 Marauder is firmware for the ESP32 microcontroller that provides a set of WiFi and Bluetooth testing tools in one package. The ESP32 is a small, inexpensive chip commonly used in hobby electronics and Internet of Things devices, and this project turns one into a portable tool for probing wireless networks and Bluetooth signals.

The README describes the project as a suite of offensive and defensive tools for WiFi and Bluetooth, aimed at security testing. Offensive in this context refers to tools used to test how networks respond to certain kinds of wireless probes, while defensive tools help detect or monitor wireless activity around you. Because this README is brief, the full feature list and setup instructions live in a separate project wiki linked from the repository page.

To get started, you download a pre-built firmware release from the releases page and flash it to compatible ESP32 hardware. For those who want to build the firmware themselves or modify it, the source code is written in C++ and is available in this repository. The project also sells a dedicated hardware unit through the author's website, so you can purchase a ready-made device rather than sourcing and assembling components yourself.

The README is short and intentionally points outward to the wiki for any deeper details. If you are evaluating this tool, the wiki is the right place to understand what individual features do and how to use them responsibly. The project is licensed under an open-source license and has attracted a large number of users given its focus on accessible wireless security tooling for hobbyist hardware.
