I'M BUILDING A BROWSER FOR REVERSE ENGINEERS

Summary from the TLDR Dev newsletter

This article goes over the process of building a custom browser for web reverse-engineering to streamline the process of analyzing browser fingerprinting and anti-bot techniques. The project started with a simple browser extension for hooking JavaScript functions but evolved to use the Chrome Devtools Protocol for deeper access. Eventually, Chromium was forked to create custom events for stealthier instrumentation. The final browser includes features like deobfuscation, property overrides, and automated decryption of fingerprinting payloads.
