Using GoldenEye: A Lightweight HTTP DoS Testing Tool

GoldenEye is a powerful yet lightweight tool designed to simulate HTTP-based Denial-of-Service (DoS) attacks on web servers. Created for security professionals and researchers, GoldenEye helps you evaluate your server’s resilience under heavy traffic. As always, ensure you have explicit permission before testing any system.

What is GoldenEye?

GoldenEye is an open-source Python tool available on GitHub that floods a target web server with HTTP requests to assess its capacity to handle stress. While its primary use is for penetration testing and load evaluation, the insights you gain can help identify performance bottlenecks and security vulnerabilities.

Installation

GoldenEye is simple to set up. Begin by cloning the repository and running the script with Python:

git clone https://github.com/jseidl/GoldenEye.git
cd GoldenEye
python3 goldeneye.py -h

The help command (-h) displays available options so you can customize your testing parameters.

Usage Examples

Below are some practical examples to help you get started with GoldenEye:

1. Basic Attack Simulation

To perform a basic HTTP DoS simulation against a target URL:

python3 goldeneye.py http://target-website.com

This command begins sending a continuous stream of HTTP requests to the specified target.

2. Customizing Attack Parameters

You can tailor the test by adjusting the duration and the number of concurrent worker threads. For instance, to run the test for 60 seconds with 20 worker threads:

python3 goldeneye.py http://target-website.com -s 60 -w 20

Here, -s 60 sets the duration to 60 seconds, and -w 20 designates 20 worker threads to simulate simultaneous traffic.

Best Practices

  • Ethical Use: Only use GoldenEye on systems you have explicit permission to test. Unauthorized usage can have legal consequences.
  • Controlled Environment: Run tests in a staging or lab environment to prevent disruption of live services.
  • Monitor and Analyze: Use server monitoring tools to track performance during tests. This helps identify potential bottlenecks or vulnerabilities that could be exploited during a real attack.

Final Thoughts

GoldenEye is a valuable tool in the security tester’s arsenal, providing a straightforward method for simulating HTTP DoS attacks. By incorporating GoldenEye into your testing workflow, you can better understand how your web server responds under stress and identify areas for improvement. Remember to always test responsibly and within legal boundaries.

Happy testing!
