Anthropic identified 24,000+ fraudulent accounts generating 16M+ exchanges with Claude from DeepSeek, Moonshot AI, and MiniMax. The agent-specific targeting is key: Moonshot (3.4M exchanges) targeted agentic reasoning and tool use; MiniMax (13M) targeted agentic coding; DeepSeek (150K) targeted reasoning. Anthropic deployed behavioral fingerprinting classifiers and "response shaping" to reduce extractive value. Two new arXiv papers (CMI logit purification + trace rewriting) provide complementary technical defenses. (Anthropic)

Anthropic identified industrial-scale capability theft: 24K fake accounts generating 16M+ exchanges from DeepSeek, Moonshot, and MiniMax. MiniMax pivoted to new models within 24 hours of each Claude release — suggesting automated distillation pipelines. ---
Anthropic disclosed distillation campaigns by three Chinese AI labs through 24,000 fraudulent accounts generating 16M+ exchanges. MiniMax drove 13M (code generation focus), Moonshot generated 3.4M (targeting agentic reasoning and tool use), DeepSeek produced 150K (reasoning an...
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 exchang...
Anthropic disclosed the most comprehensive model distillation attack forensics to date. MiniMax generated 13M+ exchanges targeting agentic coding and tool use. Moonshot AI targeted agentic reasoning and computer-use agents (3.4M exchanges). DeepSeek focused on reasoning and ce...
The largest model theft accusation in AI history. Anthropic claims three Chinese companies used 24,000 fake accounts and 16 million exchanges to systematically extract Claude's capabilities — specifically targeting agentic reasoning, tool use, and coding. MiniMax reportedly pi...
DeepSeek focused on chain-of-thought reasoning (150K exchanges), Moonshot targeted agentic reasoning and computer vision (3.4M exchanges), and MiniMax targeted agentic coding and tool use (13M exchanges — the bulk of the attack). Anthropic deployed behavioral fingerprinting cl...
