Christian Herrmann – RFID Hacker | Co-Founder of AuroraSec & RRG | MCPD Enterprise ArchitectChristian Herrmann, better known in the hacker community as “Iceman”, is a co-founder ofAuroraSec and RRG, and has helped develop many of today’s most widely used RFIDresearch tools, including the Proxmark3 RDV4 and the Chameleon Mini. He is a well-knownRFID hacking and Proxmark3 evangelist, serving the community as both a forumadministrator and a major code contributor alongside other developers since 2013.Christian has spoken at hacker conferences around the world, including Troopers, Black HatAsia, DEF CON, Hardwear IO, SSTIC, NullCon, Pass-the-Salt, BSides Tallinn, BlackAlps, and SaintCon. He also runs a YouTube channel where he shares his knowledge of RFID hacking with the public.With over 14 years of experience in bespoke software development, Christian specializes in.NET platforms and is a Certified MCPD Enterprise Architect.He possesses near-unmatched expertise in the Proxmark3 architecture and various RFIDtechnologies, and has served as an instructor for Red Team Alliance (RTA), including trainingsessions at Black Hat.

My journey in cybersecurity didn't start at the finish line. I built my foundation from the ground up, working extensively as a Security Analyst and Penetration Tester. Those early years spent analyzing defenses gave me the perspective I needed to evolve into my current role as a Head RND practitioner and Red Teamer.Sharing knowledge has always been a core part of my professional growth. Since 2012, I have been actively presenting materials on network security, Man-in-the-Middle attacks, and wireless security within university environments. This passion for research eventually led me to my current specific focus: biometric security.To truly test the limits of these systems, I realized I needed to build my own arsenal. This led me to develop several custom security tools specifically for biometric device pentesting, including zksentinel, Bac0d, GAMPAR, Tab0k, B0c0r, and BA RAT.I’ve been fortunate enough to share the insights from this development journey on larger stages like IDSecConf, where I first presented "Semi-automating Vulnerability Scanner and Exploitation in Biometric Systems." Most recently, I took that research further with a talk titled "Beyond the Match: From Biometric Bypass to Full Control - The Post-Exploitation Secrets Red Teams Use."At the end of the day, my goal isn't just to break systems, but to understand them deeply. My sincere hope is that the tools and knowledge I share can serve as useful resources for others and contribute positively to our community."

Dr. Gregory Carpenter is Principal Partner at CW PENSEC and a retired U.S. Army officer with over two decades of operational experience spanning intelligence, counterintelligence, electronic warfare, deception, and security testing. He previously served in senior roles across joint and interagency environments and was recognized as NSA Operations Officer of the Year for his work in advanced operational analysis and mission execution.Dr. Carpenter’s professional focus centers on adversary modeling and the failure modes of trust, identity, and attribution under adaptive threat pressure. His work examines how emerging technologies—including cyber-physical systems, in vivo and nano-scale technologies, automation, and information operations—alter attacker behavior and invalidate long-standing defensive assumptions. He has led and advised offensive and defensive programs across cyber, information, and electronic warfare domains, with particular emphasis on how identity collapses when human operators are no longer stable or external to the systems they access.At conferences and in research settings, Dr. Carpenter translates complex adversary behavior into practical defensive insight, emphasizing how organizations must redesign identity, access control, and trust models for environments where compromise is expected rather than exceptional. He has presented at DEF CON’s Misinformation Village (2023), Adversary Village (2025), and the DEF CON Creator Stage (2024, 2025).
