Introduction

Bug bounty hunting is a critical component of modern cybersecurity, enabling ethical hackers to identify vulnerabilities before malicious actors exploit them. With platforms like HackerOne and Bugcrowd offering lucrative rewards, mastering bug bounty hunting requires a blend of technical skills, persistence, and strategic thinking. This guide covers essential commands, tools, and methodologies to help you succeed in bug bounty programs.

Learning Objectives

  • Understand core bug bounty hunting techniques.
  • Learn practical Linux and Windows commands for vulnerability assessment.
  • Master API security testing and cloud hardening strategies.

You Should Know

1. Reconnaissance with Subdomain Enumeration

Command:

subfinder -d example.com -o subdomains.txt

Step-by-Step Guide:

  1. Install Subfinder: 
    go install -v github.com/projectdiscovery/subfinder/v2/cmd/subfinder@latest
  2. Run the command to discover subdomains of example.com.

3. Save results to `subdomains.txt` for further analysis.

Why It Matters: Subdomains often expose hidden attack surfaces, including outdated software or misconfigurations.

2. Vulnerability Scanning with Nmap

Command:

nmap -sV --script vulners -p 80,443,8080 example.com

Step-by-Step Guide:

  1. Install Nmap (sudo apt install nmap on Linux).
  2. Use `-sV` for service detection and `–script vulners` to check for known vulnerabilities.

3. Target common web ports (`80, 443, 8080`).

Why It Matters: Nmap helps identify open ports and services with known exploits.

3. Exploiting SQL Injection with SQLmap

Command:

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

Step-by-Step Guide:

1. Install SQLmap (`pip install sqlmap`).

  1. Test the URL parameter `id=1` for SQL injection.

3. Use `–dbs` to list available databases.

Why It Matters: SQL injection remains a top web vulnerability, often leading to data breaches.

4. API Security Testing with Postman

Command:

curl -X GET "https://api.example.com/users" -H "Authorization: Bearer TOKEN"

Step-by-Step Guide:

  1. Use Postman or `curl` to test API endpoints.
  2. Check for insecure headers, excessive data exposure, or broken authentication.
    Why It Matters: APIs are prime targets for attackers due to poor access controls.

5. Cloud Hardening in AWS

Command:

aws iam get-account-password-policy

Step-by-Step Guide:

  1. Ensure AWS password policies enforce complexity and rotation.

2. Use AWS CLI to audit configurations.

Why It Matters: Misconfigured cloud services lead to data leaks and breaches.

What Undercode Say

  • Key Takeaway 1: Reconnaissance is the foundation of bug bounty hunting—always start with subdomain enumeration.
  • Key Takeaway 2: Automation (Nmap, SQLmap) accelerates vulnerability discovery but requires ethical use.

Analysis: The rise of bug bounty programs reflects the growing demand for proactive security. As AI-driven attacks increase, ethical hackers must stay ahead with advanced tools and methodologies. Continuous learning (e.g., via platforms like HackingHub) is essential to keep pace with evolving threats.

Prediction

By 2025, AI-powered bug bounty platforms will automate low-hanging vulnerability detection, but human expertise will remain critical for complex exploits. Ethical hacking will become a mainstream career path, with certifications like OSCP and CEH gaining more value.
