The article “FOFA Recon for Hidden HackerOne & Bugcrowd Programs” by Abhirup Konwar explores how security researchers can uncover undisclosed bug bounty programs using advanced reconnaissance techniques. Instead of solely focusing on known vulnerabilities, ethical hackers can leverage tools like FOFA, a powerful search engine for cyberspace, to discover hidden programs that may offer lucrative rewards.

You Should Know:

1. Using FOFA for Bug Bounty Recon

FOFA allows researchers to search for assets linked to HackerOne and Bugcrowd programs using specific search queries. Here are some useful queries:

 Search for HackerOne-related subdomains 
title="HackerOne" && domain="target.com"

Find Bugcrowd programs 
"Bugcrowd" && "target.com"

Search for security.txt files (may contain program info) 
body="security.txt" && domain="example.com"

2. Extracting Hidden Programs via JavaScript Files

Many bug bounty programs are referenced in JavaScript files but not publicly listed. Use tools like Waybackurls and Gau to extract URLs:

 Fetch historical URLs 
waybackurls target.com | grep -i "hackerone|bugcrowd"

Use Gau for more recent data 
gau target.com | grep -i "security.txt"

3. Automated Recon with Nuclei & FFUF

Automate the discovery of hidden programs using:

 Scan for security.txt files 
nuclei -u target.com -t ~/nuclei-templates/http/security-txt.yaml

Fuzz for hidden paths 
ffuf -w wordlist.txt -u https://target.com/FUZZ -H "Host: target.com"

4. Google Dorking for Private Programs

Google dorks can help uncover hidden program pages:

site:target.com inurl:bounty 
site:target.com inurl:security intext:"submit vulnerability"

5. Monitoring New Subdomains

Newly registered subdomains may indicate private programs:

 Use Subfinder & Amass 
subfinder -d target.com -silent | httpx -status-code 
amass enum -d target.com -passive

What Undercode Say

Bug bounty hunting is not just about finding vulnerabilities—it’s also about discovering hidden programs that offer better rewards. By leveraging FOFA, Waybackurls, Nuclei, and Google Dorks, researchers can uncover private programs before competitors. Always verify program scopes and rules before submitting reports.

Expected Output:

  • A list of undisclosed bug bounty programs
  • Extracted security.txt files
  • New subdomains linked to private programs
  • Verified endpoints for submission
