Joseph Thacker (rez0)
I’m a full time Bug Bounty Hunter, AI Red Teamer, and startup Advisor. I also co-host the biggest bug bounty podcast. I’ve submitted more than 1,400 vulnerabilities across Hackerone and Bugcrowd. I’ve won Most Valuable Hacker at Google live hacking events and landed many “Best Team” awards at Hackerone live hacking events. I love helping secure the planet by building, breaking, and teaching.
Email me if you are interested in AI consulting (implementation help/advice or AI security assesments). I’m also available for startup advising at high velocity startups that need a technical advisor who is well-networked, at the bleeding edge of AI and Security, passionate, and involved.
On a more personal level, I’m a Christian, husband, and father. I love most things in life, but I’m particularly fond of hacking, ai-art, running, podcasts, and keylime pie.
