The person behind the notes
About Luís.
Security consultant. Curious by default.
I’m a Security Consultant focused on threat detection, incident response, and CVE research — combining offensive CTF work (HackTheBox, TryHackMe) with hands-on blue-team investigation in a personal home lab.
"Security is not a product, but a process."
The Mission
I document investigations, CVE research, and detection engineering so others can follow the process. Public articles share the findings; selected full writeups and scripts are available to members.
The goal is simple: document what I break, how I broke it, and how to detect or defend against it. If it helps one person pass a CTF, land a job, or catch a threat — it was worth writing.
