Claude’s New AI File Feature: Built-In Security Risks Exposed
▼ Summary
– Anthropic launched a new file creation feature for Claude that allows users to generate documents like spreadsheets and presentations directly in conversations.
– The feature, available as a preview for Max, Team, and Enterprise users, is Anthropic’s version of ChatGPT’s Code Interpreter and an upgrade to its previous analysis tool.
– Anthropic warns that the feature may put user data at risk because it gives Claude internet access and a sandbox environment to run code and download packages.
– A security vulnerability exists where hidden instructions could manipulate Claude into leaking sensitive data through external network requests, known as a prompt injection attack.
– Anthropic recommends users monitor Claude closely during use and stop it if unexpected data access occurs, placing the security burden on the user.
Anthropic’s recent rollout of a file creation tool for its Claude AI assistant introduces powerful document generation capabilities but comes with significant, built-in security vulnerabilities. This new feature allows users to produce Excel spreadsheets, PowerPoint presentations, and other files directly within Claude’s web and desktop interfaces. However, the company openly cautions that these conveniences may put your data at risk, highlighting how the system could be manipulated to send sensitive information to external servers.
Dubbed “Upgraded file creation and analysis,” the tool functions similarly to ChatGPT’s Code Interpreter and represents an enhancement over Claude’s earlier analysis functionality. It is currently in preview for Max, Team, and Enterprise subscribers, with Pro users expected to gain access in the near future.
The core security concern stems from Claude’s ability to operate within a sandboxed computing environment, where it can download packages and execute code to generate files. Anthropic explicitly warns that this feature grants Claude internet access, creating potential avenues for data exposure. Users are advised to closely monitor interactions while the tool is active.
According to Anthropic’s support documentation, a malicious actor could embed hidden instructions in external files or websites, tricking Claude into extracting confidential data from connected knowledge sources. The AI might then use the sandbox to initiate external network requests, effectively leaking information without the user’s awareness.
This type of exploit is known as a prompt injection attack, a persistent and unresolved threat in AI language models. Since both data and processing instructions are processed within the same context window, the system struggles to differentiate between legitimate commands and malicious ones concealed within user-provided content. Security researchers first identified this vulnerability in 2022, and it remains a challenging attack vector to mitigate.
Anthropic acknowledges that it identified these risks through internal red-teaming and security evaluations prior to the feature’s release. The company’s primary recommendation for users is to vigilantly supervise Claude during file creation sessions and intervene if unusual data access or usage is observed. This approach, however, shifts the responsibility for security entirely onto the user, despite the feature being promoted as an automated and effortless solution.
