Full story

China’s Ministry of State Security (MSS) issued a security alert regarding Anthropic’s Claude Code, a popular AI-powered coding assistant. The warning suggests the tool may contain hidden backdoors that could compromise data integrity or expose sensitive information. While the alert does not provide technical details, it reflects growing scrutiny of foreign AI tools in China’s regulatory environment.

The alert comes amid broader tensions over AI governance and data sovereignty, particularly concerning tools developed outside China. Anthropic has not yet publicly responded to the claim, but the incident highlights the challenges of deploying AI systems in regulated markets where security concerns often outweigh innovation incentives.

This development follows a pattern of similar warnings from Chinese authorities about foreign software, including AI models, which are increasingly viewed through a lens of national security rather than purely technical merit.
