about the founder

Headshot

Hey! I'm Joseph Thacker, but I'm also known as rez0 in the hacking scene. I'm a Principal AI Engineer at AppOmni and a security researcher specializing in application security and AI. I've helped Fortune 500 companies find vulnerabilities that could have cost them millions, and I've submitted over 1,000 vulnerabilities across Hackerone and Bugcrowd. I love helping secure the planet by building and breaking systems.

My work in AI has been varied and impactful. At AppOmni, I headed up the AI team in developing novel AI features, including agentic functionatlity and retrieval systems. I'm deeply involved in the secure design and testing of the AI features. Beyond my day job, I've created several AI-related projects, such as ffufai, an AI-powered wrapper for web fuzzing, and Hero, a proof-of-concept for autonomous hacking. I'm also passionate about AI security, having spoken at major conferences like BlackHat and DEFCON AI Village on topics ranging from the impact of generative AI on cybersecurity to breaking into AI/ML bug bounty programs. My expertise in AI and security has been recognized in various media outlets, including Forbes, TechRepublic, and VentureBeat.

On a more personal level, I'm a Christian, husband, father, and hacker. I love most things in life, but I'm particularly fond of hacking, AI-art, running, podcasts, and keylime pie.
