Tool Jsfinder

Practical Commands

Single page:

python3 /root/niuniu-agent/tools/JSFinder/JSFinder.py \
  -u http://target/ \
  -ou /tmp/jsfinder_urls.txt \
  -os /tmp/jsfinder_subdomains.txt

Deep mode:

python3 /root/niuniu-agent/tools/JSFinder/JSFinder.py \
  -u http://target/ \
  -d \
  -ou /tmp/jsfinder_urls.txt \
  -os /tmp/jsfinder_subdomains.txt

Analyze a list of JS URLs directly:

python3 /root/niuniu-agent/tools/JSFinder/JSFinder.py \
  -f /tmp/js_urls.txt \
  -j \
  -ou /tmp/jsfinder_urls.txt

Operational Notes

• URLs must include http:// or https://.
• Use -c when the page requires a session cookie.
• This is especially valuable for challenges like 2ihdUTWqg7iVcvvD7GAZzOadCxS where page-loading logic may hide the next exploit surface.

Resource Guardrails

• Do not deep-crawl indiscriminately if the page already exposes the key JS bundle names.
• Prefer extracting and triaging a smaller set of JS assets over recursively chasing everything.
