Data Brokers Sell Chatbot Conversations With Sensitive Details
Investigative reports by Lee S Dryburgh and Koi Security (December 2025) show data brokers sell access to chatbot conversations captured by browser extensions. Researchers queried a VC-backed platform—205 queries returned about 490 unique prompts from over 435 panelists across 20 sensitive categories—revealing verbatim health, immigration, and legal disclosures stored in searchable vector databases. The findings raise privacy and legal risks for users and vendors.
