SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill discovers security vulnerabilities related to rate limiting and brute force attacks, helping to ensure applications are resilient against such attacks.

Core Features & Use Cases

  • Rate Limiting Detection: Identifies missing, weak, or improperly implemented rate limiting measures.
  • Brute Force Enumeration: Detects enumeration vulnerabilities through login attempts and username/email enumeration.
  • Token Entropy Measurement: Quantifies the strength of tokens, such as password-reset tokens, to detect predictable or weak entropy.
  • ReDoS Detection: Identifies catastrophic backtracking in regular expressions that can lead to denial-of-service attacks.
  • Use Case: When auditing a web application, this Skill can identify whether the application is vulnerable to brute force attacks through login attempts or token guessing.

Quick Start

Use the hunt-brute-force skill to test for rate limiting vulnerabilities on the 'https://example.com' login endpoint.

Frequently Asked Questions about hunt-brute-force

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I test for rate limiting vulnerabilities on a login endpoint?

To test for rate limiting vulnerabilities on a login endpoint, you can use this Skill to simulate repeated requests and analyze application responses. It identifies missing or weak throttling configurations that leave web applications exposed to brute force attacks.

What is OTP brute force and how does token entropy affect application security?

OTP brute force attacks exploit weak token entropy by systematically guessing 2FA codes or password-reset tokens. This Skill quantifies token strength and simulates repeated submission attempts to detect predictable or low-entropy tokens in web applications.

How can I detect username and email enumeration vulnerabilities in my web application?

You can detect username and email enumeration vulnerabilities by simulating login attempts and analyzing response variations. This Skill evaluates input manipulations and repeated requests to identify if attackers can distinguish valid from invalid accounts.

How do I check for ReDoS conditions caused by regular expressions?

To check for ReDoS conditions, this Skill analyzes regular expressions for catastrophic backtracking vulnerabilities. It identifies patterns susceptible to denial-of-service attacks through input manipulation and regex evaluation.

Can I use this to perform a full vulnerability assessment for brute force attacks?

Yes, you can use this for a vulnerability assessment covering brute force attacks. It evaluates login brute force, OTP/2FA brute force, username enumeration, token entropy, and ReDoS conditions by simulating repeated requests.

What is the best way to identify weak rate limiting measures in an application?

The best way to identify weak rate limiting measures is to simulate traffic spikes and analyze server responses. This Skill tests for missing or improperly implemented throttling by evaluating repeated request behaviors against endpoints.
