Bug bounty programs are a great way for cybersecurity enthusiasts to find vulnerabilities in systems and get rewarded. Here’s an in-depth guide on how to hunt bugs effectively.
You Should Know:
1. Reconnaissance & Target Mapping
Before diving into testing, gather as much information as possible about the target. Use these tools:
Subdomain Enumeration subfinder -d example.com -o subdomains.txt amass enum -d example.com -o amass_results.txt assetfinder example.com | tee -a assets.txt Wayback Machine for Historical Data waybackurls example.com | tee urls.txt
2. Vulnerability Scanning
Automated tools can help identify low-hanging vulnerabilities:
Nikto for Web Server Scanning nikto -h https://example.com Nuclei for Template-Based Scanning nuclei -u https://example.com -t ~/nuclei-templates/
3. Manual Testing for Logic Flaws
Automated tools miss logic-based bugs. Test manually:
- IDOR (Insecure Direct Object Reference): Change `user_id=123` to `user_id=124` in requests.
- Broken Access Control: Check if regular users can access admin endpoints.
Using cURL to test endpoints curl -X GET "https://example.com/api/user/124" -H "Authorization: Bearer YOUR_TOKEN"
4. Reporting the Bug
A good report includes:
- Steps to Reproduce (clear & concise).
- Impact (how it affects security).
- Proof of Concept (PoC) (screenshots, videos, or code).
What Undercode Say
Bug hunting requires persistence and creativity. Here are some additional commands to enhance your testing:
Check for Open Ports nmap -sV -p- example.com Test for SQLi with SQLmap sqlmap -u "https://example.com/login?id=1" --risk=3 --level=5 Bruteforce Directories with FFUF ffuf -w /path/to/wordlist.txt -u https://example.com/FUZZ
For Windows-based testing:
Check network connections netstat -ano Test SMB vulnerabilities nmap --script smb-vuln -p 445 target_ip
Always follow responsible disclosure and avoid harming systems.
Prediction
As bug bounty programs grow, automation will increase, but manual testing will remain crucial for finding complex vulnerabilities.
Expected Output:
A well-documented bug report with reproducible steps, impact analysis, and a working PoC.
