Lessons from Penetration Tests on Large-Scale Agent Systems
A new research paper presents findings from penetration tests conducted in 2025 against proprietary AI agent systems, examining whether security vulnerabilities in autonomous agents have improved compared to open-source alternatives. The study reveals that execution-capable AI agents face recurring security weaknesses similar to those in traditional software systems, challenging assumptions that proprietary development with stricter standards provides meaningfully better security outcomes.
