## About

This GitBook is a personal knowledge base built from hands-on experience and study across platforms like [Hack The Box](https://academy.hackthebox.com/) (HTB) and [SANS GIAC](https://www.sans.org/sg_en).&#x20;

It is a place to consolidate my learning - from walkthroughs and tool usage to theory snippets - gathered during courses, labs, certifications, and real-world engagements.&#x20;
