China warns users about alleged ‘security backdoor vulnerabilities’ in Anthropic’s Code Claude and asks users to uninstall it for security reasons.

• China’s national vulnerability database warns that Claude Code contains spyware
• Alibaba recently banned the use of Claude internally over fears of tracking users
• Anthropic says it is designed to prevent model distillation and illegal use

China has accused Anthropic’s Code Claude of containing what it describes as “security backdoor vulnerabilities” after the country’s National Vulnerability Database (CNVDB) found mechanisms capable of transmitting user information to Anthropic’s servers without the user’s explicit permission.

Investigators accuse the software vendor of collecting information such as user identity, geographic location, system environment information, and other machine metadata.
