How we hacked YC Spring 2025 batch’s AI agents — Rene Brandel, Casco

A security analysis of YC AI agents reveals that the most critical vulnerabilities are not in the LLM itself, but in the surrounding infrastructure. This breakdown of a red teaming exercise, where 7 out of 16 agents were compromised, highlights three common and severe security flaws: cross-user data access (IDOR), remote code execution via insecure sandboxes, and server-side request forgery (SSRF).

Safety and security for code executing agents — Fouad Matin, OpenAI (Codex, Agent Robustness)

Fouad Matin from OpenAI's Agent Robustness and Control team discusses the critical safety and security challenges of code-executing AI agents. He explores the shift from models that *can* execute code to defining what they *should* be allowed to do, presenting practical safeguards like sandboxing, network control, and human review, drawing from OpenAI's experience building Code Interpreter and the open-source Code Interpreter CLI.
