Summary
👤
SeniorChad Seaman is a security-focused technologist and firefighter based in Columbus, Ohio, with 13 years of hands-on experience blending incident response, threat research, and full-spectrum web development. As Principal Security Researcher at Akamai he drove DDoS and malware investigations, discovered protocol-level amplification vectors, and built custom tooling and labs to attribute and analyze large-scale attacks. He also contributes as a vetted bug bounty researcher and has a deep background in web technologies dating back to early Flash, PHP, and real-time systems work. Chad pairs practical systems skills (Python, Scapy, Bash, Linux, reversing toolchains) with OSINT-driven investigations that have linked underground samples to real-world incidents. Currently serving his community as an HTFD firefighter, he brings calm under pressure and a habit of getting “hands dirty” in both emergency response and technical trenches. Notably, his long career bridges legacy web-era engineering and modern adversary research, giving him an atypical perspective on attack surfaces and defensive design.

chadillac/mdns_recon
Jan 2015 - Feb 2022
Multicast DNS and DNS service discovery daemons deployed on various systems across the Internet are misconfigured and reply to queries targeting their unicast addresses, including requests from their WAN interface. These daemons could be leveraged by attackers for sensitive information disclosure and potentially used in DDoS campaigns for reflection and in some cases amplification. This vulnerability was made public in cordination with CERT (http://www.kb.cert.org/vuls/id/550620)
