Brave has fixed a privacy issue in its browser that sent queries for onion domains to public internet DNS resolvers rather than routing them through Tor nodes. The bug was addressed in a hotfix release (V1.20.108) made available yesterday. Brave ships with a built-in feature called “Private Window with Tor” that integrates the Tor anonymity network into the browser, allowing users to access.onion websites, which are hosted on the darknet, without revealing IP address information to internet service providers (ISPs, Wi-Fi network providers, and the websites themselves.
