Anthropic Alleges Over 28 Million Claude Exchanges from Alibaba Attack

Anthropic has accused Alibaba of orchestrating the largest known attack to illicitly extract capabilities from its Claude AI model. This alleged "distillation" campaign, conducted between April 22 and June 5, 2026, reportedly generated over 28.8 million exchanges with Claude through nearly 25,000 fraudulent accounts.
Alibaba's Alleged Distillation Campaign

The operation attributed to operators affiliated with Alibaba and its AI lab, Alibaba Qwen, is described as a "distillation" effort. This process involves training a less advanced model on the outputs of a more capable one, with the aim of accelerating China's ability to replicate Anthropic's advanced capabilities, such as those found in its Mythos Preview.
Scale of the Operation

Anthropic reported that the campaign encompassed more than 28.8 million exchanges with Claude. These interactions were facilitated through almost 25,000 fabricated accounts, indicating a large-scale and systematic attempt to extract model functionalities.
Previous Similar Incidents

This incident follows a February report by Anthropic detailing similar, albeit smaller, illicit extraction campaigns. These prior operations involved Chinese AI startups DeepSeek, Moonshot AI, and MiniMax. DeepSeek's operation involved over 150,000 exchanges, Moonshot AI's over 3.4 million, and MiniMax's over 13 million exchanges.
Context of AI Security Concerns

The allegations against Alibaba come amidst broader concerns about the intellectual property of AI labs. In April, the White House accused China of industrial-scale theft of US AI intellectual property. Furthermore, on June 12, the US Commerce Department imposed restrictions on Anthropic's Mythos and Fable AI models due to concerns they could be used by military intelligence entities in China and other nations, leading Anthropic to disable global access to these models.
