Anthropic on Feb. 23, 2026 accused three Chinese AI firms—DeepSeek, MiniMax and Moonshot—of using more than 24,000 fraudulent accounts to generate over 16 million exchanges with its Claude models to extract capabilities. The company published the allegations in a blog post and tweet, naming MiniMax's 13 million interactions specifically and saying proxies enabled the activity. Anthropic said it has tightened defenses and is sharing intelligence with industry partners.
Key Points
- 1Alleges industrial-scale distillation: three firms created over 24,000 fraudulent accounts and 16 million+ exchanges.
- 2Highlights firm-level scale: MiniMax logged 13 million interactions, indicating aggressive capability extraction from Claude.
- 3Urgent call for coordination: Anthropic urges industry, cloud providers and policymakers to share threat intelligence.
Scoring Rationale
High industry-wide impact due to documented large-scale extraction, somewhat limited by reliance on a single company's public allegations.
