Hands-On Penetration Testing with Python

Building Python Scripts

This chapter will cover the core concepts of all programming languages. This includes conditional statements, loops, functions, and packages. We will see that these concepts are pretty much the same in Python as they are in other programming languages, except for some syntactical differences. But syntax just requires practice; everything else will fall into line automatically. The topics that we are going to cover in this chapter are as follows:

  • Conditional statements
  • Loops
  • Functions
  • Modules and packages
  • Comprehensions and generators

Technical requirements

Make sure you have the following pre-requisites needed to proceed further:

  • A working computer or laptop
  • Ubuntu OS (preferably 16.04)
  • Python 3.x
  • A working internet connection

Indentation

If you come from a background of a language such as Java, C, or C++, you might be familiar with the concept of grouping logically connected statements using curly braces. This is not the case, however, in Python. Instead, the logically connected statements, including classes, functions, conditional statements, and loops, are grouped using indentation. Indentation keeps the code clean and easy to read. We shall explore this in more detail in the coming sections. For now, however, let's say goodbye to braces. I recommend that you use tabs for indentation, as typing an equal number of spaces in every line becomes very time-consuming.

Conditional statements

Just like all other languages, to carry out the conditional operations, Python makes use of conditional statements. The conditional statements supported by Python are as follows:

  • if condition
  • if...else condition
  • else...if conditional ladder, known as elif in Python
Python doesn't support the switch statement.

The if condition

The if condition or the if statement takes a statement and returns either a Boolean True or a Boolean False value after evaluating the statement. If the condition returns True, the code proceeding the if statement (equally indented) is executed. If the statement/condition evaluates to False, then either the else block of code gets executed if there is one, or the block of...

Loops

Loops are utilities that every programming language has. With the help of loops, we execute tasks or statements that are repetitive in nature, which, without loops, would take up lots of lines of code. This, in a way, defeats the purpose of having a programming language in the first place. If you are familiar with Java, C, or C ++, you might have already come across while, for, and do...while loops. Python is pretty much the same, except that it doesn't support do...while loops. Thus, the loops that we are going to study in the following section in Python are the following:

  • while loop
  • for loop

The while loop

Remember that when we discussed lists in the first chapter of the book, we mentioned that lists can actually...

Functions and methods in Python

Functions and methods are used to design or make a logical unit of code that can be reused throughout the course of your script or other scripts. Functions actually form the basis of code reuse and bring modularity to the code structure. They keep the code clean and easier to modify.

It is advisable to always try to break our logic into small units of code, each of which is a function. We should try to keep the size of the method small in terms of the lines of code whenever possible.

The following code represents the basic syntax of defining methods in Python:

def print_message(message):
print(message)
statement 2
statement

Python methods do not have a return type in their definition as you might have seen in C, C++, or Java, such as void, in, float, and so on. A Python method may or may not return a value, but we do not explicitly need...

Modules and packages

Every Python script is called a module. Python has been designed with reusability and ease of code in mind. For this reason, every Python file we create becomes a Python module and is eligible to be invoked or used within any other file or script. You might have learned in Java how to import classes and reuse them with other classes. The idea is pretty much the same here, except that we are importing the whole file as a module and we can reuse any method, class, or variable of the imported file. Let's take a look at an example. We will create two files, child.py and parent.py, and put the following code in each, as follows:

The first five lines belong to child.py, and the last eight lines belong to parent.py. We will run the parent, as shown in the output. It should be noted that the imported file can be given an alias. In our case, we imported the child...

Generators and comprehensions

A generator is a special kind of iterator in Python. In other words, a Python generator is a function that returns us a generator iterator by issuing the yield command, which can be iterated upon. There might be occasions in which we would want a method or function to return us a series of values, instead of just one. We might, for example, want our method to partially carry out a task, return the partial results to the caller, and then resume the work right from the place where it returned the last value. Usually, when a method terminates or returns a value, its execution begins again from the start. This is what generators try to address. A generator method returns a value and a control to the caller and then continues its execution right from where it left off. A generator method is a normal Python method with a yield statement. The following code...

Summary

In this chapter, we discussed abut conditions, loops, methods, iterators, packages, generators, and comprehensions. All of these are widely used in Python. The reason why we covered these topics is because when we get into automating penetration testing and cyber security test cases later on, we will see these concepts widely used within our code files. In the next chapter, we will explore the object-oriented nature of Python. We will explore how to deal with XML, CSV, and JSON data in Python. We will also read about files, IO, and regular expressions.

Questions

  1. Name a real-world use case in which generators are used.
  2. Can we store a function name in a variable and then invoke it via a variable?
  3. Can we store a module name in a variable?

Description

With the current technological and infrastructural shift, penetration testing is no longer a process-oriented activity. Modern-day penetration testing demands lots of automation and innovation; the only language that dominates all its peers is Python. Given the huge number of tools written in Python, and its popularity in the penetration testing space, this language has always been the first choice for penetration testers. Hands-On Penetration Testing with Python walks you through advanced Python programming constructs. Once you are familiar with the core concepts, you’ll explore the advanced uses of Python in the domain of penetration testing and optimization. You’ll then move on to understanding how Python, data science, and the cybersecurity ecosystem communicate with one another. In the concluding chapters, you’ll study exploit development, reverse engineering, and cybersecurity use cases that can be automated with Python. By the end of this book, you’ll have acquired adequate skills to leverage Python as a helpful tool to pentest and secure infrastructure, while also creating your own custom exploits.

I loved reading this book, It covers multiple topics related to cyber security i.e Web pentest, exploit development, reverse engineering and last but not the least python based web vulnerability scanners. One can learn a lot from this book since every topic is written in simpler words which makes it easier even if you are a beginner in security. Also i would recommend to people who are at intermediate levels in cyber security.

I cannot recommend this book. The reasons why are numerous:1. There are more typos than you can shake a stick at. I know Packt is a low-end publishing company but this was ridiculous. It is almost as if whoever proofed the manuscript knew absolutely nothing about computer science. Really pathetic.2. In order to access the Python code in most of the book, you have to install Kali as a VM. Now I have been running Kali for a long time and am perfectly content with it. I cannot spare an additional server just to set up Kali VM on it. In order for me to test the source code, I thus have to either (1) type it in from the book's ugly fonts, or (2) persuade someone to send it to me. None of my emails to Packt were replied to and Khan's email address was no where to be found on the web.I am sorry that this has happened because the book is definitely leading edge. Everyone's loss here.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
