JavaScript is everywhere — but most bug bounty hunters don’t look deep enough.
In this video, I’m pulling back the curtain on one of the most overlooked attack surfaces in modern web applications: JavaScript files.
From hidden APIs to hardcoded tokens, this masterclass will teach you how to collect, dissect, and weaponize JS like a real hunter.
No extensions. No shortcuts. Just pure hacker methodology.
This is Part 1 of my complete JavaScript Analysis series — focused on recon and static analysis. Whether you’re using Burp Suite, digging through Wayback, or scraping the CDX archive — this is where your recon starts getting serious. 💥
