rate-limit-testing

What problem does it solve?

This Skill helps identify and exploit weaknesses in API rate limiting and throttling mechanisms, which can prevent brute-force attacks, credential stuffing, and denial-of-service vulnerabilities.

Core Features & Use Cases

• Rate Limit Discovery: Identifies rate limiting headers and triggers rate limiting to understand thresholds.
• Bypass Techniques: Explores various methods like IP spoofing, path variations, case sensitivity, and timing attacks to circumvent limits.
• Use Case: When testing an API login endpoint, you encounter a "429 Too Many Requests" error after a few attempts. This Skill can help you discover if changing the X-Forwarded-For header or using different casing for the username parameter allows you to bypass the limit and continue testing for brute-force vulnerabilities.

Quick Start

Use the rate-limit-testing skill to discover rate limit headers for the target API endpoint.
