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 multiple times 20{22,23,24x2,25x3} and have won the “Master of Pwn” title at the 2025 January edition of Pwn2Own competition in Tokyo Japan. Later in October of the same year, came back as @SummoningTeam (@_mccaulay, @Yogehi, @Ch0pin, @hyprdude) and all of us together won the “Master of Pwn” title at the October edition of Pwn2Own in Cork Ireland.
