Chats with Claude Containing Crypto Wallet Keys Found in Google Search Results
A Reddit user discovered on July 25th that a Google search for `site:claude.ai/share` revealed hundreds of users' shared conversations with Anthropic's Claude AI. Among the indexed chats were sensitive data, including a cryptocurrency wallet seed phrase, API keys, resumes with personal details, and numbers resembling U.S. Social Security numbers.
This occurred because the platform's "Share" function, which creates public links, lacked a `noindex` meta-tag to prevent search engines from crawling the pages. Although Anthropic's `robots.txt` file blocked crawlers, Google still indexed links found elsewhere online, leading to exposure. Publicly shared "artifacts" (like documents and dashboards) were also found, containing internal company data.
Following the discovery, Anthropic added `noindex` and `nofollow` tags, and Google began removing the pages. However, copies of the chats had already been archived on sites like GitHub. Anthropic stated users control sharing and links cannot be found unless shared directly.
This incident mirrors a similar event at OpenAI in August 2025, where a "Make this chat searchable" feature inadvertently exposed conversations. It highlights recurring privacy vulnerabilities with shared AI chatbot outputs.
