Fuzzing matters for OS security. Syzkaller is Google’s coverage-guided kernel fuzzer (powers syzbot too). It does not poke a single userspace binary: it generates syscall programs in a small langua...
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...
AFL++ is an advanced fork of AFL (American Fuzzy Lop) that incorporates numerous improvements, including: Better performance optimizations Support for QEMU, Unicorn, and FRIDA modes (for bina...
The Android Native Development Kit (NDK) is a toolset that allows you to implement parts of your Android app using native-code languages like C and C++. You can download the NDK from the official ...
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 vulne...
