To get the most out of this book

• You should have a basic knowledge of operating systems, including Windows and Linux. We will be using Linux tools and the shell heavily throughout this book, and familiarity with the environment is ideal.
• Some scripting knowledge will definitely help but it is not required. Python, JavaScript, and some PHP code will appear throughout this book.
• We will explore command and control servers in the cloud and it is highly recommended that a free account on one of the major providers be set up in preparation of following along with the examples in the book.
• A virtual machine or host running either Kali or your penetration testing distribution of choice will help you hit the ground running when trying some of the scenarios in the book.
• We routinely download code from open-source projects on GitHub, and while in-depth knowledge of Git will certainly help in this regard, it is not required.
