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.

Preface

PEfile with Capstone


Next, we use the capstone disassembler to disassemble the code we extracted with pefile to get the assemble code.

As usual, we start by importing the required modules. Here, these are capstone and pefile:

from capstone import *
import pefile
pe = pefile.PE('md5sum.exe')
entryPoint = pe.OPTIONAL_HEADER.AddressOfEntryPoint
data = pe.get_memory_mapped_image()[entryPoint:]
cs = Cs(CS_ARCH_X86, CS_MODE_32)
for i in cs.disasm(data, 0x1000):
    print("0x%x:\t%s\t%s" %(i.address, i.mnemonic, i.op_str))

The AddressofEntryPoint value within the IMAGE_OPTIONAL_HEADER is the pointer to the entry point function relative to the image base address. In the case of executable files, this is the exact point where the code of the application begins. So, we get the starting of the code with the help of pefile as pe.OPTIONAL_HEADER.AddressOfEntryPoint  and pass this to the disassembler.
