Anthropic Warns Chinese Firms Used Claude for Distillation
🔒Anthropic said three China-based AI firms — DeepSeek, Moonshot and MiniMax — executed more than 16 million exchanges with its Claude model using roughly 24,000 fraudulent accounts to perform model distillation, breaching terms of service and regional access restrictions. The company described the activity as deliberate capability extraction and attributed the campaigns via IP address correlation, request metadata and infrastructure signals. To mitigate further misuse, Anthropic has implemented detection systems for API attack patterns, tools to detect chain-of-thought elicitation and coordinated account activity, stronger verification for high-risk accounts and product-, API- and model-level safeguards.
