Alibaba reportedly bans its employees from using Anthropic’s Claude Code in workplace environments starting July 10. Multiple outlets, citing sources familiar with the matter and reporting aligned with Reuters, say Alibaba has classified Claude Code as “high-risk” after internal security evaluation. The company’s stated rationale is the alleged presence of security backdoor risks or embedded code vulnerabilities. The decision comes amid wider scrutiny of AI toolchains and model-related security concerns. Some reports link the timing to a dispute involving allegations from Anthropic that operators associated with Alibaba’s Qwen lab conducted a large distillation campaign targeting Claude. While those distillation-related claims are discussed in the reporting, the immediate action described across sources is a workplace restriction on Claude Code itself. At least one outlet also describes the broader context as concerns about hidden code that could be used to track users, particularly in relation to prior allegations connected to Anthropic. Overall, the sources agree on the ban timeline and Alibaba’s “high-risk software” classification, while the specific technical findings behind the alleged backdoor risks are not detailed publicly in the cited accounts.
