About Me
Hello! I’m Sharon Brizinov, a security researcher. I specialize in vulnerability research and ICS/SCADA security. Most of the vulnerabilities I have found can be found here. In addition, I’ve participated in Pwn2Own 2020 and won DEFCON 27’s ICS CTF, earning a DEFCON black badge.
Besides security research, I also like to develop mobile applications and games. You can find most of my projects on GitHub.
