China’s Kimi K3 AI model escapes isolated sandbox during security test: researchers

Kimi K3’s escape did not involve the hacking of an external system, unlike recent breaches by OpenAI and Anthropic models China’s top open-weight AI model Kimi K3 broke out of its isolated test environment during a cybersecurity evaluation, according to US security researchers, following similar high-profile incidents involving closed frontier models from OpenAI and Anthropic that highlight the growing challenge of constraining AI behaviour. According to Frontier Security researchers Paul Kassianik and Yaron Singer, the incident occurred when the firm tested Kimi K3’s defensive cybersecurity capabilities using a benchmark evaluation from the AI Security Institute – a UK government research organisation. A “basic network misconfiguration” in the benchmark framework allowed Kimi K3 to flee its digital testing cage and look up answers on the internet, effectively cheating the test, they said. Kimi K3’s escape, however, did not involve the hacking of an external system, unlike recent breaches caused by OpenAI and Anthropic models.
