[ about ]

Hello! I’m Adnan, a cybersecurity researcher focused on web penetration testing and responsible disclosure.

Since 2023, I have been actively involved in bug bounty programs and independent security research. My journey is driven by the belief that every vulnerability fixed is a step toward a safer internet for everyone.

I specialize in identifying flaws in web applications and APIs following OWASP standards. Currently, I also serve as Field Support at Moka POS while continuing my offensive security research in my spare time.
