About Me#

Hi, I’m Luiz, 24 - a cybersecurity enthusiast focused on web security and blockchain, and a team lead at hackersOnSteroids, Brazil’s #1 team on Hack The Box.

HoS

At hoS, I help lead an international crew of hackers, pentesters, software engineers, exploit developers and CTF grinders. We compete weekly, share knowledge internally, and build our own infrastructure and tools for collaboration and research.

I started out deep into cryptography, and today my work is mainly centered around offensive security, especially web exploitation and smart contract security.

I hold certifications such as:

PT1 - TryHackMe Junior Penetration Tester
DCPT - Desec Certified Penetration Tester
MCRTA - Multi-Cloud Red Team Analyst
CRTA - Certified Red Team Analyst
eJPT - eLearnSecurity Junior Penetration Tester
CWHI - CrowSec Web Hacking Initial
AD-RTS - Active Directory Red Team Specialist
CJCA - Certified Junior Cybersecurity Associate
CPTS - Certified Penetration Testing Specialist
CRTO - Certified Red Team Operator
C-APIPen - Certified API Pentester

When I’m not hacking, you’ll probably find me playing chess ♞, exploring new tech, or geeking out over security reports.
