This repository has everything I have learnt so far while reading the book Practical Malware Analysis

Windows Portable Executable Loader Library

CoreDawn is a lightweight terminal-driven operating system core simulator built in C for Linux environments. It serves as a conceptual model demonstrating how real operating systems manage processes, memory, communication, and system resources.

A collection of tiny but powerful programs that demonstrate how computers can be overwhelmed by CPU overload, RAM exhaustion, process storms, and system resource abuse. Cute… but deadly.

Custom heap memory

A real-time terminal-based system monitor built with C++ for macOS.

A professional security research study on Linux system resilience and kernel-level protection mechanisms. Analysis of boot process integrity, direct syscall implementation, anti-debugging, and sandbox evasion. An in-depth exploration of OS durability under adversarial stress.

A minimal Docker-like container runtime built from scratch using Python, Linux namespaces, chroot, fork/exec, and filesystem isolation to demonstrate core container internals.

Simulated Linux-like virtual file system in C++ with a custom shell and basic system calls.
