JavaScript exploitation doesn’t end at recon — it evolves at runtime.
In this advanced masterclass, we dive deep into DevTools debugging, obfuscation handling, send-message abuse, and real-time JS logic manipulation.
This is Part 2 of the JavaScript Analysis series — focused on runtime exploitation. If Part 1 helped you collect and dissect static JS files, this episode teaches you how to weaponize them in motion.
You’ll learn how to intercept frontend logic, bypass checks, decode obfuscation, and exploit hidden dev functions — all from your browser.
