Below is a simple FTP Key logger I've made in python.
Inspired by https://github.com/ajinabraham/Xenotix-Python-Keylogger
How it works:
First it checks if there is a keys.txt file under %appdata% folder.
If there isn't, it creates one and starts recording keystrokes immediately.
It uploads the keys.txt file on the ftp server every time you run the script.
