ROP

Welcome to this comprehensive guide on x86 Linux exploit development. In this series, we’ll delve into the fundamentals of binary exploitation on x86 Linux systems. Throughout this journey, we will explore various techniques and methodologies used by security researchers and hackers alike to exploit vulnerabilities, understand system weaknesses, and ultimately strengthen defenses. What to Expect? In this series, we will cover a range of topics, starting from the basics and gradually moving towards more advanced techniques.

In the world of binary exploitation, gadgets are crucial building blocks for bypassing modern security defenses. Whether you’re attacking vulnerable software in a CTF or conducting real-world vulnerability research, Return-Oriented Programming (ROP) and other gadget-based techniques can turn the simplest bug into a powerful exploit. But what are gadgets, and how do tools like Ropper, ROPgadget, and one_gadget help us find and use them? In this blog post, we will take a deep dive into gadgets, from understanding what they are and why they’re essential in modern exploitation, to mastering the use of tools like Ropper, ROPgadget, and one_gadget for advanced gadget hunting.
