Anthropic's Claude Model Targeted in Large-Scale AI Distillation Attack by Chinese Labs
In February 2026, Anthropic, a U.S.-based AI startup, reported that three Chinese AI laboratories—DeepSeek, Moonshot, and MiniMax—conducted large-scale 'distillation' attacks to extract capabilities from Anthropic's Claude model. These labs utilized 24,000 fraudulent accounts to send approximately 16 million requests to Claude, aiming to enhance their own AI models. This unauthorized extraction of intellectual property not only violated Anthropic's terms of service but also posed significant national security risks by potentially enabling offensive cyber operations and mass surveillance. ([cyberscoop.com](https://cyberscoop.com/anthropic-accuses-chinese-labs-ai-distillation-cyber-risk/?utm_source=openai)) This incident underscores the growing threat of AI model distillation as a method for intellectual property theft. The scale and sophistication of these attacks highlight the urgent need for robust security measures and regulatory frameworks to protect proprietary AI technologies from unauthorized exploitation.
