Claude Private Chat Leak: Closed-Source LLMs Must Pay Their Security Debt

This morning I was scrolling through Reddit in the lab when I saw a post that nearly made me spill my coffee.

I quickly tried it myself and indeed found dozens of public conversation links, one of which even contained an unencrypted SSH private key.
