# Introduction

This GitBook is a collection of practical notes covering **Windows, Linux, Active Directory, privilege escalation, pivoting**, and related topics. It’s intended to be used as a **checklist and reference** for labs, CTFs, certifications, and even real-world penetration testing engagements.

The content will continue to evolve over time as I learn and refine my approach, with plans to add more material such as **web penetration testing** and **Linux privilege escalation** techniques.

{% hint style="info" %}
This collection is a living ***work in progress*** and will continue to be updated and expanded as needed.
{% endhint %}
