From Manual Guessing → Full Recon Automation

✍️ Introduction

Most beginners waste time doing this:

  • Manually guessing endpoints
  • Clicking around apps
  • Missing hidden APIs

Meanwhile, experienced hunters do something different:

👉 They automate endpoint discovery + testing at scale

In this guide, I'll show you:

  • How to generate thousands of endpoints automatically
  • How to filter and test them fast
  • The exact workflow I use in real bug bounty recon

🧠 Why Endpoint Discovery Matters

Modern apps are API-driven.

That means:

  • /api/user
  • /v1/account
  • /internal/config

👉 These endpoints are where real vulnerabilities live:

  • IDOR
  • Auth bypass
  • Data exposure

If you're not finding endpoints… 👉 you're missing bugs.

⚙️ The Automation Stack

Here's the exact stack:

🔍 Step 1 — Generate Endpoints Automatically

We combine multiple sources:

echo target.com | gau | katana | hakrawler | anew endpoints.txt

👉 What this does:

  • gau → pulls historical URLs
  • katana → crawls deeply (JS included)
  • hakrawler → fast link discovery

🌐 Step 2 — Find Live Endpoints

Not all endpoints work.

Filter them:

cat endpoints.txt | httpx -silent -o live.txt

👉 Now you only keep:

  • Responding endpoints
  • Real attack surface

💣 Step 3 — Fuzz Hidden Endpoints

Now we go deeper.

ffuf -u https://target.com/FUZZ -w /usr/share/seclists/Discovery/Web-Content/common.txt -mc 200,403

👉 This discovers:

  • Hidden directories
  • Admin panels
  • Backup files

🧪 Step 4 — Automatic Vulnerability Testing

Now we scan endpoints for real bugs:

cat live.txt | nuclei -t exposures,misconfig,auth -severity medium,high,critical

👉 Nuclei will detect:

  • Misconfigurations
  • Exposed files
  • Auth issues

⚡ Full Automation Pipeline

This is the real power:

echo target.com | gau | katana | hakrawler | anew endpoints.txt
cat endpoints.txt | httpx -silent -o live.txt
ffuf -u https://target.com/FUZZ -w /usr/share/seclists/Discovery/Web-Content/common.txt -mc 200,403
cat live.txt | nuclei -t exposures,misconfig,auth -severity medium,high,critical

👉 One workflow =

  • Thousands of endpoints
  • Tested automatically
  • Vulnerabilities surfaced fast

🧠 Pro Tips (What Most People Miss)

  • Always combine tools → one tool = limited results
  • Focus on:
  • /api/
  • /auth/
  • /user/
  • Save everything → reuse later
  • Run scans overnight (huge advantage)

💡 Real Impact

Using this workflow, you can:

  • Find hidden APIs
  • Discover admin panels
  • Detect critical misconfigs

👉 This is how real hunters scale.

⚠️ Ethical Use Disclaimer

Use this knowledge responsibly.

  • Only test systems you have permission to test
  • Respect bug bounty program scope
  • Never target unauthorized systems
