Wireless Rubber Ducky for Raspberry Pico W

Info

This is a Rubber Ducky for Pico W that can be controlled wirelessly, over wifi (is there a name for this kind of rubber ducky?). Note that you need a Raspberry Pico W, not a Pico, as you need the wireless functionality in order to host a webserver.

A rubber ducky emulates a keyboard/mouse, sending keystrokes to the target computer. With this repo you can make your own using a Raspberry Pico W for just $6, and connect to it over Wifi, as it hosts a webserver where you can input commands to run and send keystrokes!

Installation & Usage

First, clone the repository onto your computer. Then:

Hold down the BOOTSEL button on the Raspberry Pico W as you plug it in.
Drag the adafruit-circuitpython-raspberry_pi_pico_w-en_US-8.0.0-beta.4.uf2 file into the drive. It will disconnect and boot again with CircuitPython. Note that all previous data on the pico will be erased.
Drag code.py, creds.py and index.html from this repository onto the Pico W. Note: the Pico W will automatically run code.py when it is powered on.
In creds.py, replace "SSID HERE" and "WIFI PASSWORD HERE" with your wifi SSID and password.
Install the required libraries using circup. Install circup through pythom3 -m pip install circup, then do circup install --auto to automatically install the required libraries based on imports in code.py. New release of adafruit_httpserver was not in circup, please drag the lib folder onto the drive (it contains all the required libraries adafruit_hid and adafruit_httpserver).
Now the wireless rubber ducky is done. Upon being powered, it should host a webserver at port 80. You can search for its IP address through nmap your_local_ip/24 -p 80 and looking for a name such as PicoW.lan with port 80 open.
Visit the IP address at port 80, to be prompted with a webpage. There, you can enter keystrokes to be sent:
- To type text, simply type the text on the same line. Use special keys such as > ENTER DOWN for line breaks (see below).
- To press special keys, the format is > KEY UP/DOWN such as > TAB DOWN.
  - You can see all the available special keys here.
- There is a special > SLEEP <milliseconds> command for delays.
- To use the mouse, such as clicking, dragging and moving, use MOUSE commands:
  - To MOVE the mouse:
    - > MOUSE MOVE x y moves the mouse x right and y down.
    - Example: > MOUSE MOVE 1000 -500 moves the mouse right 1000, and up 500
  - To CLICK the mouse:
    - > MOUSE CLICK mouse_button
    - Example: > MOUSE CLICK 1 performs a left click.
  - To HOLD down a mouse button:
    - > MOUSE UP/DOWN mouse_button
    - Example: > MOUSE DOWN 1 holds down left click.
    - Example: > MOUSE UP 1 releases left click.
To terminate the webserver, press Terminate button on the webpage. The server will crash itself, and will only be up again when the Pico W is restarted (such as plugged in again).

Additional

You may want to hide the USB by preventing the Pico W from showing up as a USB drive when plugged into a victim's computer. If so, read carefully:

boot.py, which is ran before code.py when powered, contains code that will do so. HOWEVER, this will soft-lock the Pico W. Also, uncomment the line of code which does so. It's there to prevent accidentally soft-lock.
If you ever soft-lock it, you can either hold down the BOOTSEL button, and nuke the flash by dragging flash_nuke.uf2 (from here) into the Pico W drive, which will make it show up as a USB when configured again.
The other option is to exploit the RCE in the code, since the server will still run, so you may be able to edit contents of boot.py from that. See #TODO and have fun exploiting!

TODO

It's possible to gain RCE because of how special keys are parsed. This should be fixed (or can serve as a backdoor if needed?? not a bug it's a feature)

keyboard.press(eval(f"Keycode.{key}"))

this GUI is garbage, needs to be improved...
about the live textbox: add replay functionality? be able to record/replay same keys pressed again?
Password protect the webserver so other people can't access it??
When software Pico W bluetooth support comes out, definetly going to look into making this bluetooth compatible (will be much easier to use, connecting to wifi is a hassle >.<)
