Katana crawler — JavaScript endpoint discovery and deep-crawl flags
50k ft — Why care?
Part two of a Katana walkthrough: use the JavaScript-crawl flag to pull endpoints out of JS files that a basic crawl misses, set crawl depth with -d, and write results to a file. Demoed against a local CTF VM; only for systems you own or are authorized to test.
10k ft — Key takeaways
• Enable JS crawling to surface hidden API routes during recon.
• Increase -d depth for thorough crawls and save output for later fuzzing.
• Practice on CTF boxes, not third-party sites.

Transcript excerpt
This is part two of using Katana. Now if you use this CLI flag you can specifically search for JavaScript endpoints. It can uncover specific routes that a basic crawl might miss. You can also use the dash D flag here to specify the depth of the scan so it's not just some basic scan you can really do a deep crawling session here. By the way this URL here is not a legitimate URL this is just my virtual machine running a CTF. Let's see if we get anything. Here we go. So we go onto the full URL JavaScript crawl and we're basically outputting it into a Katana full.txt file saving all these results. And if you want to learn more of this I've got a school community for you to check out the link is in the bio.
