Fingerprinting

Cloudflare's Turnstile service is requiring users to enable fingerprintable WebGL, raising privacy concerns. The change involves using WebGL for browser fingerprinting, which can uniquely identify devices.

An article discusses how Mullvad VPN's exit IP addresses can be used as a fingerprinting vector to identify users, undermining the privacy protections the service is designed to provide. The research reveals that despite Mullvad's privacy-focused approach, the exit IPs themselves may leak identifying information about users.
