Scan Multiple JavaScript Files

To scan multiple JavaScript files, use a text file containing URLs of the JS files and process them with xargs:

Waybackurls - JS Recon for IP, Hostname & URL

waybackurls vulnweb.com | grep '\.js$' | awk -F '?' '{print $1}' | sort -u | xargs -I{} bash -c 'python lazyegg.py "{}" --js_urls --domains --ips' > jsurls.log && cat jsurls.log | grep '\.' | sort -u

Chrome Extension

LazyEgg includes a Chrome extension that logs real-time JavaScript files loaded by the browser. It captures the difference in JavaScript files loaded for unauthenticated and authenticated users. When a user logs in, additional JavaScript files specific to the authenticated user are loaded. This allows you to see how the JavaScript environment changes upon authentication, providing insight into the dynamic content and functionality provided to logged-in users.

To install the extension:

Open Chrome and navigate to chrome://extensions/.
Enable "Developer mode" using the toggle switch.
Click "Load unpacked" and select the chrome_extension directory from the LazyEgg repository.
