China’s top intelligence official publicly warned that two U.S. artificial intelligence models could raise cyber risks for China’s critical infrastructure. Ministry of State Security chief Chen Yixin said Anthropic’s Claude Mythos and OpenAI’s GPT-5.5-Cyber reflect a new phase of automated vulnerability discovery, malware development, and AI-assisted attack chaining, though he did not claim the models had been used in specific attacks. The warning was paired with a new Cyberspace Administration of China AI governance framework focused on autonomous agents and loss-of-control risks.
Why it matters: This matters because it signals possible new Chinese policy, review, or restriction pressure on foreign AI systems over cybersecurity grounds, with implications for providers, researchers, and organizations using these tools. Defenders and policy teams should watch for follow-on regulation, access limits, and further evidence of AI-assisted offensive cyber use.
