Bio

Hi! I'm Csome (Shaomin Chen).

Ph.D. student at University of Chinese Academy of Sciences (2024 - present), B.Sc. from South China Normal University (2020 - 2024). I mainly work on Linux kernel security and exploitation, and occasionally on symmetric cryptanalysis.

CTF player focusing on Pwn. Also a bit of a musician (NetEase Cloud Music artist) — just not a singer.
