Man in the middle device to capture input from a keyboard and save it to a file that later can be retrieved while maintaining output from the keyboard to victim's device.
- Arduino Leonardo compatible board,
- Raspberry Pi (tested on Zero),
- some cables,
- some means of connecting a keyboard to the RPi (e.g. USB A female port or micro to female A cable),
- SD card.
- Download the Arduino code and
$ pio run -t uploadwith PlatformIO installed, - Setup RPi with Raspbian, establish connection to your Wi-Fi, enable SSH,
- SSH into the Pi and
$ mkdir /home/pi/ak2_projekt && mkdir /home/pi/ak2_projekt/logs, - While in the Pi
$ pip install getch pyserial - Copy main.py from this repo's RPi directory into
/home/pi/ak2_projekt, - Append
python /home/pi/ak2_projekt/main.pyto/etc/profile, - Connect devices according to instructions below
| RPi | Arduino |
|---|---|
| 5V | VCC |
| GPIO14/TXD | RX |
| GPIO15/RXD | TX |
| GND | GND |
Keyboard <-(USB)-> RPi

- Make sure nothing is flashing to Arduino, plug it off the computer and put it back in.
- Everything should be working, the logs are in the folder you created earlier, Have fun!
To leave the program, try CTRL + ? or CTRL + -. Have in mind that the only way to resume it is to restart the devices and the output from the keyboard will be halted. CTRL + S is bugged and when pressed halts any output to victim's PC until CTRL + Z is pressed. There are probably many bugs and unhandled cases which you are welcome to tinker with.
