Henrique Cunha Ethical Hacker & Red Team Student.
I study and practice ethical hacking through authorized labs, Red Team methodology, Linux, automation, electronics and scientific thinking.
Looking for internship, mentorship and learning opportunities in ethical hacking, cybersecurity, Linux and technical projects.
About
Security mindset with an engineering base.
I am a technical Electronics student from Sao Paulo, Brazil, focused on pentest, Red Team methodology, ethical hacking, Linux and programming. My work connects practical cybersecurity with automation, embedded systems and scientific reasoning.
I care about projects that can be tested, documented and improved. The direction is clear: build real technical capability, communicate findings cleanly and keep offensive security inside authorized, ethical and useful contexts.
Skills
Honest, practical and organized by domain.
No inflated expert labels. Just the areas I am building, using and documenting with discipline.
Learning Now
Current study direction.
This is where I am putting focused effort right now, while keeping projects public and documented.
Web Pentest
OWASP basics, APIs, authentication, sessions and reportable findings.
Red Team
Scope, recon, evidence, OPSEC notes and attack-chain thinking in authorized labs.
Linux
Terminal workflow, automation, Docker, Git and reproducible environments.
Reporting
Turning technical findings into clear evidence, impact and mitigation.
Cloud / AD
Cloud IAM and Active Directory fundamentals as next security tracks.
