How to prevent web tracking scripts from using proxies

Sophisticated advertisers conceal tracking scripts (like Google Analytics) behind subdomains designed to mimic legitimate parts of the site you are visiting (CNAME cloaking), effectively bypassing traditional ad-blocking blocklists.

Network signature analysis against CNAME cloaking

Static blocklists fail against local logical subdomains. AdBlock Network overcomes this by performing network signature analysis. The extension executes asynchronous read-only requests to multiple independent endpoints to refresh its firewall, enabling the Advanced layer to intercept connections with camouflaged proxy servers.
