Private Claude Chats Including Crypto Data Found on Google

Users discovered that shared Claude chat links were appearing in public search results. While these chats were intended to be private, the share feature creates a public web page accessible to anyone with the link. Because these pages were indexed by search engines, they became discoverable through simple queries. This incident has raised alarms for crypto users who may have mistakenly shared sensitive information, such as private keys or wallet credentials, during AI sessions.

Technical details suggest the issue stems from how search engines handle pages blocked by robots.txt files. When a site blocks a crawler, the search engine cannot see the internal instructions to keep the page private. Consequently, while the search results did not display the chat content directly, the links remained clickable. This creates a significant risk, as any exposed private key allows for unauthorized access to funds that cannot be recovered once compromised.

It is important to note that no widespread fund thefts or confirmed leaks of working seed phrases have been reported as a direct result of this specific issue. However, the event serves as a sharp reminder for traders to avoid pasting private keys or sensitive credentials into any AI interface. Users should check their account settings under privacy tabs to review and unshare any active links that may still be accessible to the public.

Anthropic has faced similar indexing reports in the past. To stay safe, treat all AI interactions as public logs. Always assume that any link generated by a third party service could be discovered by others, and never share secrets that could lead to the loss of your crypto assets.
