Alibaba to ban Claude Code in workplace over alleged backdoor risks, source says

Alibaba will prohibit employees from using Anthropic's Claude Code within workplace environments starting July 10. According to a source cited by Reuters, the ban is driven by alleged backdoor risks. This action follows accusations from Anthropic that operators linked to Alibaba's Qwen lab executed the largest known distillation campaign against Claude. The company is implementing these restrictions to address security concerns regarding the integration of the tool within its internal professional operations.
