Tools used for penetration testing are often purchased or downloaded from the Internet. Each tool is based on a programming language such as Perl, Python, or Ruby. If a penetration tester wants to extend, augment, or change the functionality of a tool to perform a test differently than the default configuration, the tester must know the basics of coding for the related programming language. Coding for Penetration Testers provides you with an understanding of the scripting languages that are commonly used when developing tools for penetration testing. It also guides you through specific examples of custom tool development and the situations where such tools might be used. While developing a better understanding of each language, you are guided through real-world scenarios and tool development that can be incorporated into a tester's toolkit. This completely updated Second Edition focuses on an expanded discussion on the use of Powershell and includes practical updates to all tools and coverage. Discusses the use of various scripting languages in penetration testing Presents step-by-step instructions on how to build customized penetration testing tools using Perl, Ruby, Python, and other languages Provides a primer on scripting, including, but not limited to, Web scripting, scanner scripting, and exploitation scripting Includes all-new coverage of Powershell.
