Type the right query into Google over the weekend and you could read strangers’ conversations with Claude. Some held medical records. Some held company files and children’s phone numbers.
The chats were not hacked or leaked in any technical sense. Users had shared them through a Claude feature built for that. Search engines then indexed the pages like any other public link.
Anthropic’s position is that nothing failed. The system, it says, is working as intended.
How it surfaced
A Reddit user flagged it on Saturday. The search operator “site:claude.ai/share” returned a long list of shared Claude chats. 404 Media first reported it on Monday, and the rest of the tech press followed within hours.
