As the Lead Solutions Architect at XBOW, he bridges the gap between application development, penetration testing, and software supply chain defense. His recent work examines how generative AI codes like a junior developer with root access. He researches how AI models fail at security fundamentals and demonstrates how attackers use these tools to write exploits. Julian authored the book *Mastering the Art of Application Security Testing* and shares technical field notes on his blog. ## Past Sessions ### World Congress 2026 Europe 路 July 8, 2026 Berlin, Germany - [GenAI Is a Junior Dev With Root Access](https://www.wearedevelopers.com/videos/100191-genai-is-a-junior-dev-with-root-access) 路 30 min 路 馃帴 Watch recording ### World Congress 2025 路 July 9, 2025 Berlin, Germany - [Code Red: When Your Tools Turn Against You ](https://www.wearedevelopers.com/events/world-congress-2025/sessions/510-code-red-when-your) 路 120 min ### World Congress 2024 路 July 17, 2024 Berlin, Germany - [Let鈥檚 write an exploit using AI](https://www.wearedevelopers.com/videos/1004-let-s-write-an-exploit-using-ai) 路 120 min 路 馃帴 Watch recording - [Let's write an exploit using AI](https://www.wearedevelopers.com/events/world-congress-2024/sessions/360-let-s-write-an) 路 30 min ## Videos - [GenAI Is a Junior Dev With Root Access](https://www.wearedevelopers.com/videos/100191-genai-is-a-junior-dev-with-root-access) 路 Julian Totzek-Hallhuber - [Let鈥檚 write an exploit using AI](https://www.wearedevelopers.com/videos/1004-let-s-write-an-exploit-using-ai) 路 Julian Totzek-Hallhuber ## Links - [LinkedIn](https://www.linkedin.com/in/jtotzek/)
