Introduction

Bug bounty programs have become a critical component of modern cybersecurity, incentivizing ethical hackers to uncover vulnerabilities before malicious actors exploit them. Offensive security tools play a pivotal role in this ecosystem, enabling researchers to automate and enhance their testing methodologies. This article explores key commands, techniques, and emerging trends in offensive security for bug bounty hunters.

Learning Objectives

  • Understand essential offensive security tools and commands for bug bounty hunting.
  • Learn how to leverage automation in vulnerability discovery.
  • Explore future trends in offensive security tool development.

You Should Know

1. Automating Reconnaissance with Subfinder

Command:

subfinder -d example.com -o subdomains.txt

Step-by-Step Guide:

Subfinder is a subdomain discovery tool that scours multiple sources to enumerate subdomains.

1. Install Subfinder: `go install github.com/projectdiscovery/subfinder/v2/cmd/subfinder@latest`

  1. Run the command above, replacing `example.com` with your target domain.
  2. Results are saved in `subdomains.txt` for further analysis.

2. Exploiting XSS Vulnerabilities with XSS Hunter

Command:

xsshunter -u https://your-xss-hunter-instance.com

Step-by-Step Guide:

XSS Hunter helps detect blind XSS vulnerabilities.

  1. Deploy your XSS Hunter instance (self-hosted or cloud).
  2. Inject the payload `”>` into input fields.
  3. Monitor the XSS Hunter dashboard for callback alerts.

3. Password Spraying with Kerbrute

Command:

kerbrute passwordspray -d example.com users.txt Password123

Step-by-Step Guide:

Kerbrute automates Kerberos pre-authentication attacks.

1. Compile a list of valid usernames (`users.txt`).

  1. Run the command to spray a common password (Password123).

3. Review output for successful authentications.

4. API Security Testing with Postman

Command (Postman Collection Runner):

newman run api_test_collection.json

Step-by-Step Guide:

Postman automates API security testing.

  1. Create a collection of API requests in Postman.

2. Export the collection as `api_test_collection.json`.

  1. Run the collection with Newman to test for vulnerabilities like IDOR or broken authentication.

5. Cloud Hardening with AWS CLI

Command:

aws iam update-account-password-policy --minimum-password-length 12

Step-by-Step Guide:

Hardening AWS environments is critical for bug bounty hunters targeting cloud assets.
1. Ensure AWS CLI is configured with proper credentials.
2. Enforce a strong password policy with the command above.

3. Verify changes in the AWS IAM console.

What Undercode Say

  • Key Takeaway 1: Offensive security tools are evolving rapidly, with automation playing a central role in bug bounty success.
  • Key Takeaway 2: Ethical hackers must stay updated on emerging tools to maintain a competitive edge.

The increasing sophistication of offensive tools underscores the need for continuous learning. As bug bounty programs expand, researchers who master automation and cloud security will dominate the field. Future tools may integrate AI-driven vulnerability discovery, further transforming the landscape.

Prediction

The next wave of offensive security tools will likely incorporate machine learning to identify zero-day vulnerabilities autonomously. This shift will accelerate bug discovery but also raise ethical questions about responsible disclosure and tool misuse.
