OpenAI details how prompt injection attacks on AI agents have evolved from simple string overrides to social-engineering-style manipulation, succeeding ~50% of the time in testing. They argue defense requires system-level design (constrained permissions, minimal footprint, human-in-the-loop checkpoints) rather than just input filtering. Directly relevant to anyone building agentic systems that interact with untrusted external content.
