How do automated browsers hide from detection tools?

Automated browsers often use native patching to mask their automation by altering browser APIs or properties. BotRefund looks for these mismatches as part of its 106 independent checks. A single patching anomaly is not enough to call something a bot because privacy tools or corporate networks can also cause changes. That is why BotRefund cross-checks each signal with browser, network, device, and behavior data before reaching a conclusion.
