Bash shell scripting is essential for penetration testing because it’s versatile and efficient and integrates thoroughly with the Unix-based systems commonly used in cybersecurity assessments. In this book, the author leverages his decades of experience in IT and pentesting to help you automate repetitive tasks, rapidly analyze data, and craft sophisticated exploits, boosting your effectiveness and productivity. You’ll get to grips with Bash basics, set up a hacking environment, and create basic scripts, before exploring file management, text processing, and manipulation. The chapters will guide you through advanced topics such as networking, parallel processing, and regular expressions. From there, the book will move on to practical applications, walking you through reconnaissance, web application and infrastructure pentesting, privilege escalation, persistence, and pivoting, all using Bash scripting. You’ll also get a solid understanding of advanced topics, including evasion and obfuscation tactics, integrating AI into penetration testing workflows, and implementing DevSecOps practices. By the end of this book, you’ll be well-versed with Bash shell scripting techniques tailored to penetration testing scenarios.
