Alibaba has officially announced a ban on the use of Anthropic's Claude Code in workplace environments starting July 10 due to alleged security risks stemming from embedded backdoors. According to sources familiar with the matter, the restriction will apply across Alibaba's internal work environments and takes effect on July 10. The decision follows a report by Chinese financial outlet Yicai that said Alibaba had identified what it described as embedded 'backdoor' risks in the AI coding assistant. The company reached this decision due to alleged security risks linked to embedded backdoors in the coding assistant, though no official statement has been issued by Alibaba as of publication time. The ban comes just days after developers discovered that Claude Code contained mechanisms that inspected user environments, including timezone and proxy-related information, and inserted subtle markers into prompts sent to Anthropic's servers.
The security concerns center around Claude Code's ability to help identify China-linked users, according to a person familiar with the order. Claude Code is Anthropic's AI coding assistant for software developers that has become popular among programmers in China despite the company's restrictions on access by users and entities in China. An Anthropic employee revealed on Tuesday on X that the feature was 'an experiment we launched in March' intended to prevent account abuse by unauthorized resellers and protect against model distillation. This revelation adds new dimensions to the security concerns that prompted Alibaba's workplace ban, as the tool's functionality extends beyond basic coding assistance to include user behavior monitoring and geographic identification capabilities.
The Alibaba decision comes amid escalating tensions between the two companies. In June, Anthropic wrote to the US Senate Committee on Banking, Housing, and Urban Affairs, accusing Alibaba of trying to extract its AI capabilities. Anthropic specifically accused Alibaba of illicitly extracting its Claude AI model capabilities in what it said was the largest known attack of its kind on the company, according to a letter seen by Reuters. The distillation helps accelerate China's ability to reach Anthropic's advanced Mythos Preview capabilities, as reported by Reuters. The move comes as tensions between Alibaba and Anthropic have escalated in recent weeks, highlighting growing concerns among financial institutions in Hong Kong as advanced AI tools become more deeply integrated into software development and financial services workflows.
Alibaba employees are being directed to use the company's own coding platform Qoder as an alternative to Claude Code, according to sources familiar with the order. This represents a strategic shift toward internal development tools as the company addresses security concerns. The decision reflects Alibaba's commitment to maintaining control over its internal technology ecosystem while managing external security risks. The move comes as tensions between Alibaba and Anthropic have escalated in recent weeks, highlighting growing concerns among financial institutions in Hong Kong as advanced AI tools become more deeply integrated into software development and financial services workflows.
