# USB Keystrokes
If you have a pcap containing the communication via USB of a keyboard like the following one:
2021-10-18 11:21:18 +00:00
![](< .. / . . / . . / . gitbook / assets / image ( 613 ) . png > )
2021-09-05 13:49:24 +00:00
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
```
