SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill identifies and demonstrates vulnerabilities in Multi-Factor Authentication (MFA) and Two-Factor Authentication (2FA) implementations, helping to prevent unauthorized access.

Core Features & Use Cases

  • Pattern Detection: Identifies 7 distinct patterns of MFA/2FA bypass.
  • Auth Flow Analysis: Traces the authentication flow for MFA validation and rate limiting.
  • Validation Reporting: Validates attacker session reaching post-MFA state and reports findings.
  • Use Case: A security researcher can use this Skill to discover and report vulnerabilities in a web application's authentication process, particularly those related to MFA/2FA bypass.

Quick Start

Execute the hunt-mfa-bypass skill to initiate an MFA/2FA bypass assessment against a target application.

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

FAQPage Schema
How do I detect MFA bypass vulnerabilities in a web application?

This Skill discovers MFA bypass vulnerabilities by tracing authentication flows to identify 7 distinct bypass patterns and validating if an attacker session reaches the post-MFA state. It reports findings for security testing scenarios.

What is two-factor authentication bypass testing and how does it work?

Two-factor authentication bypass testing works by tracing authentication flows to detect validation and rate limiting flaws. It identifies 7 distinct bypass patterns and validates attacker sessions reaching the post-MFA state to report vulnerabilities.

How do I test my 2FA implementation for authentication flow vulnerabilities?

You test 2FA implementation vulnerabilities by executing an assessment against the target application. The Skill traces the authentication flow for MFA validation and rate limiting, detecting 7 bypass patterns to validate and report findings.

Can I use this MFA vulnerability assessment for any web application?

You can use this MFA vulnerability assessment for security testing scenarios across web applications. It applies to applications requiring analysis of authentication flows, detection of MFA/2FA bypass patterns, and validation reporting.

What is the best way to validate an attacker session after an MFA bypass?

The best way to validate an attacker session after an MFA bypass is to trace the authentication flow and confirm the session reaches the post-MFA state. This Skill performs validation reporting to demonstrate the vulnerability.

Does this Skill require external dependencies to test MFA vulnerabilities?

This Skill requires no external dependencies to test MFA vulnerabilities. It uses internal scripts to analyze authentication flows, identify 7 bypass patterns, and validate attacker sessions without additional setup.
