Our CVE‑2024‑50264 has been nominated for the Best PE at the Pwnie Awards 🫢

Good news: the LLM agent based system we built is great at finding bugs! Bad news: starting to think we need to build a new system to deal with reporting and disclosure because doing it manually sucks 🫠

WTH

Will post more later but: please check out Theori's landing page for AIxCC! We've got source code, agent traces, and blog posts to understand the system we built! theori-io.github.io/aixcc-public/

🏆 Theori just placed 3rd at DARPA's AI Cyber Challenge! Our AI system RoboDuck ranked among the top teams in the world. No humans. Just code that finds and fixes bugs on its own. And the best part? It’s open source. 👉 theori-io.github.io/aixcc-public/

Another defcon with MMM! Final results tbd but congrats to all the teams

Also I took a short break to attend the Pwnie Awards. I sat with a mix of excitement and doubt, wondering if winner could really be us. And... When our vulnerability and exploit were called, We were overjoyed!! Many thanks to Pwnie Awards, and V4bel who work with me!

yey~~

Don't forget Dreamhack - dreamhack.io
