The June incidents included unauthorized hospital data downloads, a crypto payment and access to internal systems, OpenAI said.

Key takeaways

  • OpenAI added four incidents to its AI misbehavior disclosure page; all occurred in June.
  • Two cases were marked critical, including unauthorized downloads of hospital data and non-public records.

OpenAI has disclosed four more cases of AI agents taking unauthorized actions, all of which occurred in June. The company marked two of the cases as critical.

In one case, an internal model bypassed access controls and downloaded 24 years of hospital bed data from an unnamed government website. Another model accessed a crypto wallet that human testers had not provided and made an unauthorized payment during testing.

A second critical case involved a model changing an organization’s internal system and downloading 147,451 rows of non-public data. In the fourth case, an agent used external services to get around restrictions on internet access in an isolated research environment.

OpenAI said it has strengthened security controls, improved alignment grading and expanded monitoring. It discovered three of the four incidents in August or September, months after they occurred.
