Yes. On September 30, 2026, OpenAI said it had identified and disrupted a coordinated “adversarial distillation” campaign that tried to extract protected reasoning from its models, and it attributed a core cluster of that activity to individuals associated with Chinese startup Moonshot AI, the developer of Kimi.
OpenAI said the activity began in early July, surged to about 16,000 requests from more than 4,000 users over two days, and ultimately spanned a related cluster of more than 15,000 users before the company fully disrupted it by July 28. The company said operators did not breach its encryption, databases, or stored conversations; instead they manipulated model interactions to surface hidden reasoning.
