Anthropic accuses Alibaba of mass unauthorized access to Claude via fake accounts

Anthropic alleges Alibaba created thousands of fraudulent accounts to access its Claude AI model without authorization, likely to extract proprietary model behavior or training data. The claim is unverified and Alibaba has not responded, but if confirmed it signals escalating corporate espionage in the AI sector. This could heighten tensions between US and Chinese tech firms and prompt stricter access controls.
