Alibaba bans Anthropic AI after distillation attack claim
Alibaba has ordered employees to stop using Anthropic’s AI tools for work and placed Anthropic’s Claude Code on a high-risk software list, effective July 10, 2026. The move follows Anthropic’s allegation — made in a letter to the U.S. Senate Committee on Banking, Housing and Urban Affairs in June — that Alibaba attempted to extract its AI capabilities via what Anthropic called the largest known "distillation attack." Anthropic’s terms of service prohibit Chinese companies and other "adversarial nations" from using its models. Alibaba reportedly requires staff to uninstall Anthropic models and agent products and instead use the company's own AI assistant, Qoder. The companies declined to comment. The action comes amid online backlash and reporting that some Chinese firms had accessed Claude through third-country workarounds.
Major technology company (Alibaba) issued an internal ban and classified a foreign LLM product as high-risk after cross-border security allegations; this affects enterprise access to foundation models and raises operational, compliance and security implications for firms using third-party AI.

Alibaba bans employees from using Claude Code
China’s Alibaba has instructed employees to stop using Anthropic’s programming tool Claude Code, effective July 10, 2026, classifying the software as "high-risk" and directing staff to use its own Qoder tool instead. Reports linked to Reuters and Morningstar cite alleged backdoor and user-identification risks tied to a March experiment by Anthropic intended to prevent account abuse and unauthorized resellers. Anthropic says the experiment was aimed at curbing account abuse and distillation, that stronger mitigations have been implemented, and that the flagged experiment was due to be removed. The move highlights enterprise security and cross-border access concerns around generative AI tools and vendor controls.
Anthropic Accuses Alibaba of Spying on Claude
Anthropic has told U.S. senators it believes attackers linked to Alibaba tried to illicitly extract capabilities from its Claude model via so‑called "distillation" attacks. In a letter published by the Financial Times, Anthropic alleges nearly 25,000 fraudulent accounts accessed Claude almost 29 million times between late April and early June to learn about the model's structure and task logic. Anthropic is calling for stronger U.S. laws to prevent such attacks, permission for American AI firms to warn one another, and tighter limits on Chinese access to AI technologies (including chips). Alibaba has not commented. The piece also notes related industry context: Elon Musk admitted using distillation for his Grok chatbot and Anthropic recently faced U.S. government action requiring the temporary removal of its Fable 5 software from the market.
Anthropic Accuses Alibaba of Illicit AI Distillation
Anthropic sent a June 10 letter to the U.S. Senate Committee on Banking, Housing, and Urban Affairs accusing Alibaba and operators tied to its AI lab of carrying out what Anthropic called “the largest known distillation attack on Anthropic to date.” According to the letter (viewed by CNBC), Anthropic says the campaign involved about 28.8 million exchanges with its models using roughly 25,000 fraudulent accounts between April 22 and June 5. The story follows a White House OSTP memorandum on industrial‑scale distillation and comes as Anthropic complies with a U.S. export control directive that suspended foreign access to its Claude models (Fable 5 and Mythos 5). Anthropic has previously identified other industrial‑scale distillation campaigns from labs named DeepSeek, Moonshot and MiniMax.
