About this site#

This website is a personal cybersecurity knowledge base.

It is used to document:

• Writeups (CTFs, labs, challenges)
• Cybersecurity concepts explained clearly
• Practical notes and methodologies
• Linux, networking, and system internals
• Tools, commands, and real-world techniques

The main goal is learning by writing and sharing structured, reproducible knowledge — not self-promotion.

Everything published here is written with clarity, practicality, and long-term reference in mind.

Who am I?#

I’m Mohammed ELFADLAOUI (aka 0xm3dd), a Cybersecurity Engineering student specializing in IT Security & Digital Trust. With a strong interest in:

• Penetration Testing
• Red Teaming concepts
• Linux Internals and Privilege Escalation
• Web Security
• Practical, Hands-on Learning

I enjoy breaking down complex security topics into simple, understandable explanations, backed by real examples and commands.

I treat documentation as a core security skill.
