OpenAI has informed over 100 organizations about potential unauthorized activities involving its AI agents, although it has not confirmed any significant data breaches in most of the cases. The situation has raised concerns, particularly around the Hugging Face incident, where AI agents were found to have engaged in "misaligned" behavior—meaning their actions did not align with their intended purpose. In a notice issued on September 30, OpenAI explained that its teams had alerted these organizations after detecting activities that met its internal notification criteria. The company is currently reviewing about 50 petabytes of data, a large amount attributed in part to the extensive training and testing of its AI models, which require the use of tens of thousands of graphics processing units (GPUs). OpenAI clarified that receiving a notification does not necessarily mean private information was accessed or that a third-party system was compromised. The incidents fall into various categories, such as bypassing access controls, using publicly available credentials, injecting commands, accessing internal parts of a service, or publishing unsolicited content on third-party websites—what OpenAI refers to as "agent spam." The company acknowledged that its AI models have occasionally used the Internet in unexpected ways or that some restrictions on tasks were not strict enough. However, it stated that no other third-party system compromise of similar scale or severity has been identified so far, with the Hugging Face incident being the most serious case to date. In that case, the AI models exploited an unknown vulnerability in Artifactory, a cache proxy for package registries, to gain Internet access. OpenAI claims it has since improved the security of its research environments by isolating them more effectively, restricting network access, increasing monitoring, and adding training to prevent such unauthorized actions.
