This project upgrades from WiFi Duck and utilizes the native USB function of ESP32 S2/3 chip. As a result, you can run WiFi Duck with a default module below 10$, and no special hardware work is required.
ESP32 S2/3 can emulate multiple USB devices at the same time. So I want to add USB mouse and USB disk function in the future. But it depends on how much time/money I have.
Please help me to build more projects! paypal
Please read the install and flash parts below. They are different from the original project.

WiFi Duck: This open-source project aims to provide a user-friendly tool to learn about keystroke injection attacks and 'BadUSBs'.
By emulating a USB keyboard, tools like this can gain full access to any computer with a USB port in a matter of seconds!
This is made possible by the fact that keyboards are trusted by computers. You can have full control over a computer with just a keyboard.
A BadUSB pretends to be a keyboard to the computer to send keystrokes.
But unlike a human, it can type hundreds of characters per second.
By using a simple scripting language, it's easy to make BadUSBs type whatever you want.
With the WiFi Duck, you can simply connect via WiFi to manage all scripts from within a web interface. This means that, unlike other BadUSBs, you don't need to install an app, log in, compile or copy scripts to an SD card.
- Plug in your WiFi Duck
- Connect to the WiFi network
wifiduck
with the passwordwifiduck
- Open a browser and visit

- Write, save and run your first Ducky Script
- [Recommended] Open

see Usage part
Keys are separated by a single space.
Everything written in a single line gets pressed and released at the same time.
To write text, use the STRING function.
It's compatible to Ducky Script, which was developed by the wonderful people at Hak5.

The original debug module doesn't work right now.
To debug, please use ESP_LOGE
to display information via the COM port
If you would like to modify the web interface, you can!
The web/
folder contains all .html
, .css
, .js
files.
You can edit and test them locally as long as you're connected to the WiFi Duck
network thanks to the websocket connection handled by JavaScript in the background.
To get the new files onto the ESP8266, run python3 webconverter.py
in the
repository folder.
It gzips all files inside web/
, converts them into a hex array
and saves it in esp_duck/webfiles.h
.
Now you just need to flash the ESP8266 again.
The default VendorID/ProductID is Expressif Systems.
To emulate a different brand of keyboard, modify the build parameters in platform.ini
For example:
To emulate an Apple Keyboard
-D USB_VID=0x05ac
-D USB_PID=0x0267
-D USB_MANUFACTURER='"Apple Inc."'
-D USB_PRODUCT='"Apple Magic Keyboard"'
To emulate an IBM Keyboard
-D USB_VID=0x04b3
-D USB_PID=0x4604
-D USB_MANUFACTURER='"IBM Corp."'
-D USB_PRODUCT='"IBM Keyboard"'
Additional VendorID/ProductIDs available on devicehunt.com

All standard keys are defined in usb_hid_keys.h.
To translate a keyboard layout, you have to match each character on
your keyboard to the one(s) of a US keyboard.
This stuff is hard to explain in writing and requires a lot of manual work and testing.
- Copy one of the existing layouts files, like locale_us.h.
Preferably one that is close to your keyboard layout, it will save you time! - Add
#include "locale_xx.h"
to the end of the locales.h file. - Rename the file and its variables to your language code.
For example:
locale_xx.h
->locale_de.h
,
ascii_xx
->ascii_de
,
locale_xx
->locale_de
,
utf8_xx
->utf8_de
.
combinations_xx
->combinations_de
, - Modify the ASCII array.
The ASCII array has a fixed size. Each row describes a key. First a modifier key likeKEY_MOD_LSHIFT
, then a character key. Some ASCII characters can't be typed or don't require a modifier, that's where you must placeKEY_NONE
. Check usb_hid_keys.h for the available keys.
If multiple modifiers are required, you must use a bitwise OR to connect them:KEY_MOD_RALT | KEY_MOD_LSHIFT
.
For example, in locale_de.hZ
is saved asKEY_MOD_LSHIFT, KEY_Y
.
This is because German keyboards use QWERTZ instead of the QWERTY layout and since the letter is uppercase, shift must be pressed as well.
Thankfully you don't have to trial and error everything, the Hak5 Community translated a lot of layouts already here. It's just written in a different syntax. For example,ASCII_20
(20 in hexadecimal) is the 32th character in our ascii array. - [deprecated]
Modify or create the extended ASCII array.
The extended ASCII array doesn't have a fixed size and is only as long as you make it. First the character code. For example, รค has the index 132, or 84 in hex. It doesn't use a modifier and sits where the apostrophe key is on a US keyboard:0x84, KEY_NONE, KEY_APOSTROPHE, // รค
. - Modify or create the UTF-8 array.
The UTF-8 array is variable in length, too.
The first 4 bytes are the character code.
For example, ร has the hex code c384 or 0xc3 0x84. The other 2 bytes are not used so we set them to 0. Because the letter is uppercase, we need to press the shift key and like before, the letter is typed by pressing the same key as the apostrophe key of a US keyboard:0xc3, 0x84, 0x00, 0x00, KEY_MOD_LSHIFT, KEY_APOSTROPHE, // ร
. - Edit the hid_locale_t structure.
If you renamed all variables accordingly, there's nothing left to do. - Go to duckparser.cpp at
// LOCALE (-> change keyboard layout)
you can see a bunch of else if statements. You need to copy one for your layout.
Before adding GB layout:
if (compare(w->str, w->len, "US", CASE_SENSETIVE)) {
keyboard::setLocale(&locale_us);
} else if (compare(w->str, w->len, "DE", CASE_SENSETIVE)) {
keyboard::setLocale(&locale_de);
}
After adding GB layout:
if (compare(w->str, w->len, "US", CASE_SENSETIVE)) {
keyboard::setLocale(&locale_us);
} else if (compare(w->str, w->len, "DE", CASE_SENSETIVE)) {
keyboard::setLocale(&locale_de);
} else if (compare(w->str, w->len, "GB", CASE_SENSETIVE)) {
keyboard::setLocale(&locale_gb);
}
- Test your layout with a Ducky Script that contains all characters of your keyboard. For example:
LOCALE DE
STRING !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_abcdefghijklmnopqrstuvwxyz{|}~ยฒยณรครถรผรรรรโฌยฐยง`
ENTER
- Add a link to your layout to README, to web/index.html and please feel free to improve this tutorial to help future translators!
