Introduction
Bug bounty hunting is a rewarding career path in cybersecurity, where ethical hackers identify vulnerabilities in systems and report them for rewards. This article explores essential commands, tools, and methodologies for aspiring bug bounty hunters, inspired by Bahadır Birinci’s recent success in the field.
Learning Objectives
- Understand key tools and commands for vulnerability discovery.
- Learn how to validate and report security flaws effectively.
- Gain insights into the bug bounty workflow and best practices.
You Should Know
1. Reconnaissance with Subdomain Enumeration
Command:
subfinder -d example.com -o subdomains.txt
Step-by-Step Guide:
- Install SubFinder.
- Run the command to discover subdomains of
example.com.
3. Review `subdomains.txt` for potential targets.
Purpose: Subdomain enumeration helps identify overlooked entry points for testing.
2. Vulnerability Scanning with Nikto
Command:
nikto -h https://example.com -output scan_results.html
Step-by-Step Guide:
1. Install Nikto (`sudo apt install nikto`).
- Scan a target web server for common vulnerabilities.
- Analyze `scan_results.html` for findings like outdated software or misconfigurations.
Purpose: Automated scanning accelerates initial vulnerability assessment.
3. Exploiting SQL Injection with SQLmap
Command:
sqlmap -u "https://example.com/login?id=1" --dbs
Step-by-Step Guide:
1. Test the URL for SQL injection vulnerabilities.
2. Use `–dbs` to list available databases.
3. Extract sensitive data responsibly and report it.
Purpose: SQLmap automates detecting and exploiting SQLi flaws.
4. Cross-Site Scripting (XSS) Testing
Command:
xsstrike -u "https://example.com/search?q=test"
Step-by-Step Guide:
- Clone XSStrike.
2. Test input fields for XSS vulnerabilities.
3. Validate payloads and document findings.
Purpose: XSS testing ensures user inputs are sanitized.
5. API Security Testing with Postman
Command:
curl -X GET https://api.example.com/users --header "Authorization: Bearer token"
Step-by-Step Guide:
- Use Postman or cURL to test API endpoints.
- Check for insecure data exposure or broken authentication.
3. Report unauthorized access or excessive data leaks.
Purpose: APIs are common attack surfaces requiring rigorous testing.
6. Network Scanning with Nmap
Command:
nmap -sV -p 1-1000 example.com
Step-by-Step Guide:
1. Scan for open ports and services.
- Identify outdated or vulnerable services (e.g., FTP, SSH).
3. Document findings for further exploitation or mitigation.
Purpose: Nmap reveals network-level weaknesses.
7. Cloud Security: AWS S3 Bucket Checks
Command:
aws s3 ls s3://bucket-name --no-sign-request
Step-by-Step Guide:
1. Check for publicly accessible S3 buckets.
2. Report misconfigured permissions or exposed data.
3. Use AWS CLI for automated audits.
Purpose: Cloud misconfigurations are a top attack vector.
What Undercode Say
- Key Takeaway 1: Automation tools like SQLmap and SubFinder streamline discovery but require ethical use.
- Key Takeaway 2: Bug bounty success hinges on persistence, continuous learning, and adherence to responsible disclosure.
