About

My name is Sina Kheirkhah also known as @SinSinology I’m a full-time vulnerability researcher with a passion for popping shells across all kinds of targets—server-side enterprise solutions, hardware devices and I also do reverse engineering, low-level exploitation, attacking .NET/Java stacks, bypassing mitigations, chaining bugs, and all the good stuff.

To highlight some of my work, I’ve been a Pwn2Own contestant for four consecutive years 20{22,23,24,24.5,25} and have won the “Master of Pwn” title at the 2025 Pwn2Own competition in Tokyo.

Before I forget, I wouldn’t be able to do what I do if it wasn’t because of the so many talented other security researchers out there, here are some of those researchers who have directly/indirectly influenced my craft, so make sure to follow their work:
