Welcome to my blog!

Wow! You make it to this website. Thanks for coming in! This website is all about sharing this awesome path of discovery I’m in. I usually do some CTFs and HackTheBox stuff but I’m interested in radio and any other thing that has to deal with computers and electronics. This is an open space, so feel free to contact me in case there are any doubts of what I post here.

CTF Writeups

CTF (Capture The Flag) are competitions where we solve different cybersecurity tasks to find the secret (flag) at the end of the challenge. There are several categories depending on the type of the challenge, some of them are: Web, Forensic, OSINT (Open Source Intelligence), Cryptography, PWN (Binary Explotation), Reverse Engineering, RF (Radio Frequency), Hardware, etc.

I have special interest in OSINT, Web and Forensic challenges and I participate with team ISwearIGoogledIt looking for scoring as much points as possible while developing new skills in different cybersecurity areas.

You can find all my CTFs writeups (solutions and explanations) here:

Flipper Zero

I backed FlipperZero from the early stage of the kickstarter and I enjoy it very much. It is nowadays my favorite tool for pentesting and I have developed some addons to use external modules such as NRF24 and CC1101. Also, I developed the VoyagerRF board, a multipurpose WiFi auditing board to take all your tools everywhere. Find out more in the following post:

An easy and automated dropbox for remote pentesting assessments using OpenVPN and Kali Linux. We will configure the complete setup using RDP and SSH as connection protocols.
