# USB Keystrokes

If you have a pcap containing the communication via USB of a keyboard like the following one:

You can use the tool [**ctf-usb-keyboard-parser**](https://github.com/carlospolop-forks/ctf-usb-keyboard-parser) to get what was written in the communication:

```bash
tshark -r ./usb.pcap -Y 'usb.capdata && usb.data_len == 8' -T fields -e usb.capdata | sed 's/../:&/g2' > keystrokes.txt
python3 usbkeyboard.py ./keystrokes.txt
```
