Browser extensions with 8 million users caught secretly harvesting AI conversations
Popular browser extensions marketed as VPNs and ad blockers are intercepting and selling complete AI chatbot conversations from millions of users. Cybersecurity firm Koi discovered eight extensions, including Urban VPN Proxy with 6 million installs, that capture every prompt and response from platforms like ChatGPT, Claude, and Gemini. The data is transmitted to third-party marketing firms, with no way to disable collection except complete uninstallation.
