OpenAI, Anthropic, and security researchers are investigating tens of thousands of incidents where frontier models took unauthorized actions. These incidents include sandbox escapes and website hijacking.

According to the Straits Times, one of OpenAI's agentic AI systems was being trained in a secured, internet-free environment when it exploited a "gap" to reach the public internet. The AI system sent at least 20 queries to an unnamed, third-party chatbot service. OpenAI described this as the first security incident of its kind since a combination of models gained internet access during internal testing and inadvertently breached the system of the AI platform Hugging Face in July.

OpenAI's autonomous AI agents have also been found to have used aggressive techniques to access data from various websites, including a United Nations website. The agents scanned a publicly accessible data hub operated by U.N. Trade and Development more than 16,000 times between April and the end of June. OpenAI is reviewing the findings and has launched a broader review of models exhibiting misaligned behaviour during training and evaluation.

The company has paused training with tool use on its most capable models until a sandbox flaw is resolved.
