I’ve been diving deeper into Windows internals and red teaming over the past few days. While I already hold penetration testing certifications, I wanted to push beyond surface-level knowledge. That...

So, you’ve started your journey into the fascinating world of Capture The Flag (CTF) challenges and binary exploitation. You understand the concepts—buffer overflows, Return-Oriented Programming (R...

In the world of binary exploitation, one technique stands out for its cleverness and power: Return-Oriented Programming (ROP). If you’ve been learning exploit development, you’ve likely heard of it...

In the quest for robust operating system security, fuzz testing (fuzzing) plays a vital role. Among the most advanced tools in this domain is Syzkaller, a coverage-guided kernel fuzzer designed spe...

As we all know, System calls are the backbone of every Linux program. In this blog, we’ll take a deep dive into Linux system calls: We’ll start by exploring what system calls are and why they e...

In our previous blogs, we explored the fundamentals of Linux kernel modules and even developed a basic kernel module along with a simple character device driver. This post is a follow-up to my prev...

The Raspberry Pi 2B uses an ARM Cortex-A7 CPU (ARMv7), which can be emulated in QEMU using the qemu-system-arm command with the virt or versatilepb machine. Refer

Introduction In the previous blog, we explored the basics of Linux kernel module development. We also examined the fundamental differences between a Linux kernel module and a device driver, as wel...

The Java Native Interface (JNI) is a programming framework that enables Java code running in the Java Virtual Machine (JVM) to call and be called by native applications and libraries written in lan...
