How To Hack: Learning From Duplicate Bug Bounty Reports

Even when a bug bounty submission is marked as a duplicate, the process of discovering and reporting vulnerabilities is invaluable. It reinforces real-world attack vectors, sharpens testing methodologies, and improves security research skills.

You Should Know:

1. Common Web Vulnerabilities to Test

SQL Injection:
```
' OR '1'='1' --
```

Test with automated tools like `sqlmap`:

sqlmap -u "https://example.com/login?id=1" --dbs

Cross-Site Scripting (XSS):

<script>alert('XSS')</script>

Test manually or with tools like Burp Suite or XSStrike:

python3 xsstrike.py -u "https://example.com/search?q=test"

Cross-Site Request Forgery (CSRF):

Check for missing CSRF tokens:

curl -X POST -d "user=admin&action=delete" https://example.com/admin/action

2. Essential Bug Hunting Tools

Burp Suite (Manual Testing)

OWASP ZAP (Automated Scanning)

zap-cli quick-scan --spider -r https://example.com

Nmap (Network Recon)
```
nmap -sV --script vuln example.com
```

3. Bug Bounty Methodology

1. Reconnaissance:

subfinder -d example.com -o subdomains.txt

2. Fuzzing Directories:

ffuf -w wordlist.txt -u https://example.com/FUZZ

3. Automated Scanning:

nikto -h https://example.com

4. Handling Duplicate Reports

Analyze Public Disclosures:

gobuster dns -d example.com -w subdomains-wordlist.txt

Improve Testing Techniques:
```
waybackurls example.com | grep ".php"
```

What Undercode Say

Duplicate reports are part of the bug bounty journey. They validate your skills and reinforce best practices. Keep refining your approach, automate repetitive tasks, and stay updated with new attack vectors.

Expected Output:

A structured bug hunting workflow.
Improved manual and automated testing techniques.
Better understanding of real-world vulnerabilities.

Prediction

Bug bounty programs will increasingly use AI to detect duplicates faster, but manual testing will remain crucial for uncovering logic flaws and advanced exploits.
