Hi! I’m Marcelo Bregieira, a Cybersecurity Engineer and a Sergeant in the Portuguese National Guard (GNR), digital forensics as team leader.

I hold the Certified Penetration Testing Specialist (CPTS) certification from Hack The Box, and I have a strong passion in offensive security, vulnerability research, and real-world security challenges.

This blog is mainly dedicated to technical write-ups from Capture The Flag (CTF) challenges, labs, and other hands-on cybersecurity exercises. My goal is to document methodologies, tools, and lessons learned while solving these challenges, in a way that can help others improve their technical skills.

Occasionally, I will also explore other topics related to cybersecurity, such as digital forensics, investigative techniques, and security research.

Cybersecurity is a constantly evolving field, and continuous learning is essential. Through this blog, I hope to share knowledge, document my learning journey, and contribute to a stronger and safer digital ecosystem.
