I am an IT security researcher and professional.
I have discovered multiple significant vulnerabilities and am developing Open Source security tools.
My previous work includes the discovery of TLS vulnerabilities like ROBOT in RSA and flaws in AES-GCM implementations. I also helped discover multiple flaws in the use of STARTTLS in E-Mail protocols. I ran the Fuzzing Project, an effort to improve the security of Open Source software, and am developing multiple Open Source security tools.
I have presented my work at security conferences like Black Hat, DEF CON, Nullcon, Deepsec, and many others.
