FEATURED CHROME BROWSER EXTENSION CAUGHT INTERCEPTING MILLIONS OF USERS' AI CHATS

Summary from the TLDR InfoSec newsletter

A widely trusted Chrome and Edge extension, Urban VPN Proxy, was updated in 2025 to inject JavaScript that hooks network APIs, silently captures all AI chatbot prompts and responses, plus metadata, and then sends them to Urban VPN's analytics servers. The data is shared with parent company BIScience for commercial insights, despite “AI protection” marketing and a privacy policy that downplays risks. Security teams should review browser extension permissions, monitor network traffic for unusual API calls, and enforce policies restricting the installation of unverified extensions to prevent data exfiltration by malicious extensions such as Urban VPN Proxy.
