Python is an easy-to-learn cross-platform programming language that has unlimited third-party libraries. Plenty of open source hacking tools are written in Python and can be easily integrated within your script. This book is divided into clear bite-size chunks, so you can learn at your own pace and focus on the areas that are of most interest to you. You will learn how to code your own scripts and master ethical hacking from scratch.

Who this book is for

This book is for ethical hackers; penetration testers; students preparing for OSCP, OSCE, GPEN, GXPN, and CEH; information security professionals; cyber security consultants; system and network security administrators; and programmers who are keen on learning all about penetration testing.

What this book covers

Chapter 1, Warming up– Your First Antivirus-Free Persistence Shell, prepares our Kali Linux as the attacker machine. It also prepares out a target and gives a quick overview of the TCP reverse shell, the HTTP reverse shell, and how to assemble those.

Chapter 2, Advanced Scriptable Shell, covers evaluating dynamic DNS, interacting with Twitter, and the use of countermeasures to protect ourselves from attacks.

Chapter 3, Password Hacking, explains the usage of antivirus free loggers, hijacking the KeePass password manager, Firefox API hooking, and password phishing.

Chapter 4, Catch Me If You Can!, explains how to bypass a host-based firewall outline, hijack Internet Explorer, and bypass reputation filtering. We also interact with source forge and Google forms.

Chapter 5, Miscellaneous Fun in Windows, focus on exploiting vulnerable software in Windows and different techniques within privilege escalation. We'll also look into creating backdoors and covering our tracks. 

Chapter 6, Abuse of Cryptography by Malware, provides a quick introduction to encryption algorithms, protecting your tunnel with AES and RSA, and developing hybrid-encryption keys.

To get the most out of this book

You'll need an understanding of Kali Linux and the OSI model. Also, basic knowledge of penetration testing and ethical hacking would be beneficial.

You will also need a 64-bit Kali Linux and a 32-bit Windows 7 machine with Python installed, on Oracle VirtualBox. A system having a minimum of 8 GB RAM is recommended.
