UPDATE: justcallmekoko has launched a new iteration of the Marauder (v6) for $60, which includes a sleeker look, options for external antennas, and the ability to update its firmware over Wi-Fi and/or SD card.
The original article continues below.
Penetration testers and security analysts looking for an easily-pocketable tool for Bluetooth and Wi-Fi testing purposes have another option, in the form of the ESP32 Marauder from security tester justcallmekoko.
“The Marauder is a portable penetration testing tool created for Wi-Fi and Bluetooth analysis,” the pseudonymous justcallmekoko explains. “It comes installed with a suite of offensive and defensive tools all running on an ESP32. I was inspired to create this tool by Spacehuhn’s deauther project. I wanted to bring similar functionality to the ESP32 and introduce new Bluetooth capabilities to the tool.”
“The tool itself serves as a portable device used to test and analyze Wi-Fi and Bluetooth devices. Use this tool and its firmware with caution as the use of some of its capabilities without explicit consent from the target owner is unlawful in most countries.”
The firmware justcallmekoko has created is compatible with any ESP32-based development board, and designed to provide feedback via a 2.8″ ILI9341-based TFT touchscreen display. The pre-assembled versions take the firmware and install it onto a custom PCB with Espressif ESP32-WROOM chip at its heart and an integrated lithium-polymer charging circuit for power on the go.
The entire unit is then enclosed in a 3D-printed chassis, which in the case of the pre-assembled version comes in a selection of colors: black, “Galaxy Black,” neon green, and silver. Justcallmekoko warns, however, that “most of the work so far has been put into designing the hardware,” meaning that the current release has “limited firmware capabilities” — but that development is ongoing to add new features and functionality.
More details on the project can be found on GitHub, where the firmware, hardware, and 3D print files can be downloaded; the pre-assembled ESP32 Marauder, meanwhile, can be purchased from Tindie. source
ESP32 Marauder Kit Assembly and Programming Guide
Thank you for purchasing the ESP32 Marauder Kit! Let’s get started with assembling and programming your device.
Things You’ll Need
