Hello World — Starting the Journey

Every journey has a first step. This is mine.

Who am I

I’m 0xK4iros — a software engineering student specializing in cybersecurity, currently focused on offensive security and web pentesting. Based in México, working toward eventually operating professionally in Europe.

What I’m building

Right now my focus is on web pentesting through PortSwigger Web Academy — working through every vulnerability class, building custom scripts, and developing a real methodology. Alongside that, I practice on HackTheBox to apply concepts in realistic environments.

The long term goal is bug bounty hunting, backed by a structured certification path:

PortSwigger Cert → eJPT → PNPT → OSCP → CRTO

What this blog is

A public record of the process. Writeups, scripts, lessons learned — documented as I go. No shortcuts, no skipping steps.

The name says it all — Kairos. The precise moment when conditions align and action becomes effective. That’s the standard I’m holding myself to.

See you in the next post.
