I sent email to Anthropic ([e-mail], [e-mail]) on January 8, 2025 alerting them to this issue: Claude Code Exploit: Claude Code Becomes an Unwitting Executor. If I hadn't seen Claude Code read my ssh file, I wouldn't have known the extent of the issue.

To improve the Claude model, it seems to me that any time Claude Code is working with data, the first step should be to use tools like genson (https://github.com/wolverdude/GenSON) to extract the data model and then create why files (metadata files) for data. Claude Code seems eager to use the /tmp space so even if the end user doesn't care, Claude Code could do this internally for best results. It would save tokens. If genson is reading the GBs of data, then claude doesn't have to. And further, reading the raw data is a path to prompt injection. Let genson read the data, and claude work on the metadata.
