Effective Python Penetration Testing

By: Rejah Rehim

Overview of this book

Penetration testing is a practice of testing a computer system, network, or web application to find weaknesses in security that an attacker can exploit. Effective Python Penetration Testing will help you utilize your Python scripting skills to safeguard your networks from cyberattacks. We will begin by providing you with an overview of Python scripting and penetration testing. You will learn to analyze network traffic by writing Scapy scripts and will see how to fingerprint web applications with Python libraries such as ProxMon and Spynner. Moving on, you will find out how to write basic attack scripts, and will develop debugging and reverse engineering skills with Python libraries. Toward the end of the book, you will discover how to utilize cryptography toolkits in Python and how to automate Python tools and libraries.

Screen grabbing

Screen grabber captures the victim's desktop and sends the images to a remote server. There are many Python modules that can be used to grab a raster image of the screen programmatically. We could make use of the Python Image Library (PIL) for Windows and OSX. The PIL package contains the ImageGrab module that can be used to grab screenshots.

Import the modules, here we also import the time module to sleep the execution for three seconds—allowing the user to switch the screen display before the grab:

from PIL import ImageGrab 
import time

Sleep three seconds and take a screenshot:

ImageGrab.grab().save("screen_capture.jpg", "JPEG") 

We can also take a screenshot of a specific area on screen by providing the area as follows:

ImageGrab.grab(bbox=(10,10,510,510)).save("screen_capture.jpg", "JPEG") where, bbox=(X1,Y1,X2,Y2)

The following screenshot illustrates the example:

To grab a screenshot on a Linux system, we have to use the wxPython...
