Hidden Investigations began as a small group of cybersecurity enthusiasts driven by curiosity and a shared passion for offensive security. Founded by Sakibul Ali Khan, the team started its journey in 2022, initially competing in Capture The Flag (CTF) events and quickly gaining recognition for its sharp technical skills and teamwork.

What started as a competitive team has grown into a collective of researchers, programmers, and bug hunters who are deeply committed to understanding and securing the digital world. We come from diverse academic and technical backgrounds, but we share the same mindset: always question, always explore, always improve.

At our core, we are problem solvers. We thrive in high-pressure scenarios, whether during timed CTF competitions or real-world adversary simulations. Every member brings unique strengths to the table, and collaboration is our greatest tool. We invest heavily in knowledge sharing, peer learning, and constant upskilling—not just to improve ourselves, but to uplift the community around us.

Hidden Investigations isn’t just a team; it’s a mindset. A mindset built on discipline, trust, and an unshakable commitment to cybersecurity. We believe in responsible research, open collaboration, and giving back to the cybersecurity ecosystem through tools, write-ups, and training.

From late-night debugging sessions to international CTF finals, our journey has been fueled by persistence and a love for the challenge. And we’re just getting started.
