About Me

Hands-on pentesting notes covering web, network, and Active Directory security.

Hi, I’m Sachin 👋

I’m a cybersecurity learner and CTF player focused on penetration testing and offensive security. My learning approach is strongly hands-on, combining labs, structured learning paths, and continuous practice.

This GitBook is my personal knowledge base, where I document what I learn while developing real-world security skills.

• Practicing ethical hacking in a legal and structured manner

Learn by doing. Document everything. Improve continuously.
