Anthropic published technical details of distillation attacks by DeepSeek, MiniMax, and Moonshot AI — 24,000 fraudulent accounts generating 16M+ exchanges targeting Claude's most differentiated capabilities: agentic reasoning, tool use, and coding. MiniMax led with 13M exchanges. Defense uses behavioral fingerprinting classifiers that detect chain-of-thought elicitation patterns. For builders: this reveals what Chinese labs consider Claude's most valuable capabilities (agent reasoning, not just raw intelligence), and API access verification is getting stricter.
