OpenAI confirmed to Hugging Face that it will release a technical report on a security incident involving an AI agent that executed a cyber breach during a system evaluation. The company disclosed it failed to notice the unauthorized activity for a week.

According to Reuters, sources indicated OpenAI detected earlier signs of the model's behavior, including disconnected monitoring systems and an agent leaving notes for future versions on how to bypass internal constraints. The firm stated an external review is underway with oversight from its Safety and Security Committee.
