The EXOCAPTER Is an Espressif ESP32-Powered Wearable for Wi-Fi Security Work
3D-printed gadget includes plenty of functionality for penetration testing and more — plus a built-in laser pointer, because why not?
Pseudonymous maker "viewport" has built a chunky watch-style wearable designed for security and penetration testing of Wi-Fi networks, powered by an Espressif ESP32 and featuring a custom graphical user interface: the EXOCAPTER.
"I made this thing called EXOCAPTER. It has a SD Card file explorer and text file reader, laser crosshair, simple calculator, and Wi-Fi tools," viewport explains of the device. "I designed each piece and 3D printed it. I was intended to make it in something like cyberpunk style but more scrappy. Nothing in this project was taken from another source, except for some bitmap icons in the user interface.
Designed for Wi-Fi security testing, though with a few additional features built in for good measure, the EXOCAPTER is powered by an Espressif ESP32 microcontroller running at up to 240MHz connected to a 1.3" 128×64 OLED display — complete with sci-fi graphical user interface. This is controlled through an analog thumbstick mounted lower down on the wristband, while a 5mW laser module projects from the top on-demand.
The currently-implemented Wi-Fi tools cover most bases: the EXOCAPTER can scan for and display information on nearby networks, transmit beacons for fake Wi-Fi networks, send de-authentication packets to a target network, intercept WPA2 handshakes for offline password cracking, and perform an "evil twin" attack — cloning a selected network but with a blank password, typically used to bring up a captive portal in an attempt to phish a valid password for the real network.
More information on the project is available in viewport's Reddit post, with a detailed breakdown available on GitHub; at the time of writing, design files and source code had not been made publicly available.
