About me

I'm Robiul Awal Fagun (0xRobiul) — a passionate cybersecurity researcher based in Dhaka, Bangladesh. I focus on offensive security and contribute to bug bounty platforms like HackerOne, Intigriti, Bugcrowd, and serve as a Strike Force Member at Yogosha.

// background

I thrive on uncovering security weaknesses in real-world systems — web applications, APIs, networks, cloud and Active Directory environments. Beyond breaking things, I write detailed reports with reproducible PoCs and actionable remediation guidance so teams can ship secure software.

Ranked #1 in Bangladesh on HackTheBox and previously #2 in Bangladesh on TryHackMe. I also placed 7th globally in Hacker101 CTF and actively organize and play CTFs across the country.
