Self-Hosted Program Recon via Custom Dork

When performing reconnaissance for bug bounty programs, custom Google dorks can help uncover self-hosted programs that aren’t listed on major platforms like Bugcrowd or HackerOne. Below is a powerful dork to find such programs:

-site:bugcrowd[.]com "will use the Bugcrowd Vulnerability Rating Taxonomy" 
-site:hackerone[.]com "Follow HackerOne's disclosure guidelines"

This search query excludes well-known bug bounty platforms while targeting pages that mention vulnerability disclosure guidelines, indicating potential self-hosted programs.

You Should Know:

Advanced Google Dorking Techniques

Here are more dorks to refine your search:

1. Find Private Bug Bounty Pages

inurl:/security intext:"submit vulnerability report"

2. Discover Responsible Disclosure Policies

intext:"responsible disclosure" inurl:/security

3. Locate Security.txt Files

inurl:/security.txt "contact"

4. Search for Vulnerability Disclosure Forms

inurl:/report-vulnerability intext:"bug bounty"

5. Find API Security Policies

intext:"API security policy" filetype:pdf

Automating Recon with Bash & Python

Use these commands to automate searches:

Bash Script for Dorking

!/bin/bash 
echo "Enter target domain:" 
read domain 
dork="site:$domain inurl:/security intext:'bug bounty'" 
google-chrome "https://www.google.com/search?q=$dork"

Python Script for Security.txt Discovery

import requests 
target = input("Enter domain (e.g., example.com): ") 
response = requests.get(f"https://{target}/.well-known/security.txt") 
if response.status_code == 200: 
print(f"Found security.txt:\n{response.text}") 
else: 
print("No security.txt found.")

Linux Commands for Security Researchers

  • Extract URLs from Web Pages 
    curl -s "https://example.com" | grep -Eo 'https?://[^"]+'

  • Check for Open Ports 

    nmap -p 80,443,8080 target.com

  • Analyze SSL Certificates 

    openssl s_client -connect target.com:443 | openssl x509 -noout -text

Windows Recon Commands

  • Check Active Network Connections 

    netstat -ano

  • Find Hidden Files in Directories 

    dir /a:h C:\

What Undercode Say

Reconnaissance is the foundation of ethical hacking. Mastering Google dorks, automating searches, and understanding security policies can uncover hidden bug bounty opportunities. Always verify program legitimacy before testing.

Expected Output:

  • A list of self-hosted bug bounty programs.
  • Security.txt files containing contact details.
  • Private vulnerability disclosure pages.
