Fotios Chantzis

Fotios (Fotis) Chantzis (@ithilgore) is laying the foundation for a safe and secure Artificial General Intelligence (AGI) at OpenAI. Previously, he worked as a principal information security engineer at Mayo Clinic, where he managed and conducted technical security assessments on medical devices, clinical support systems, and critical healthcare infrastructure. He has been a member of the core Nmap development team since 2009, when he wrote Ncrack under the mentorship of Gordon "Fyodor" Lyon, the original author of Nmap, during the Google Summer of Code. He later worked as a mentor for the Nmap project during the Google Summer of Code 2016 and 2017 and has authored a video course about Nmap. His research on network security includes exploiting the TCP Persist Timer (you can find his paper on the topic published in Phrack #66) and inventing a stealthy port scanning attack by abusing XMPP. Fotis has presented at notable security conferences, including DEF CON. Highlights of his work can be found at his site https://sock-raw.org/.
