SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identifies and analyzes MFA bypass weaknesses in authentication workflows to prevent authorization and session compromise.

Core Features & Use Cases

  • MFA bypass pattern analysis: Detects common misconfigurations such as missing step-up checks, OTP reuse, and pre-MFA states.
  • Workflow testing for red-team engagements: Applies to web apps, identity providers, and enterprise platforms where MFA can be bypassed.
  • Actionable guidance: Provides practical mitigations and evidence-oriented results to close gaps in MFA enforcement.

Quick Start

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

To test for MFA bypass vulnerabilities, analyze authentication workflows for missing gating checks, OTP reuse, and pre-MFA session states. Describe your MFA flow in plain English to load relevant tests and identify where token handling or session transitions fail.

What are common MFA misconfigurations in identity platforms and enterprise SSO?

Common MFA misconfigurations include missing step-up authentication checks, OTP reuse, improper remember-device behavior, and race conditions during session transitions. These weaknesses allow attackers to bypass MFA enforcement across identity platforms and enterprise SSO.

Can I use this approach to detect race conditions in authentication and session management?

Yes, you can detect race conditions in authentication by analyzing session transitions and token handling during MFA workflows. This approach identifies timing vulnerabilities that allow unauthorized session access before MFA validation completes.

Does MFA bypass testing work for red-team assessments and security testing?

MFA bypass testing is designed for authorized red-team assessments and bug-hunting. It validates MFA enforcement across web apps, identity platforms, and enterprise SSO by detecting misconfigurations, race conditions, and OTP reuse with measurable results.

What is the best way to validate MFA enforcement and prevent session compromise?

The best way to validate MFA enforcement is to analyze authentication workflows for gating weaknesses, token handling flaws, and session transition issues. This provides evidence-oriented results and recommended mitigations to close security gaps.

When should I not rely on remember-device behavior for MFA security testing?

You should scrutinize remember-device behavior during MFA security testing if the workflow allows pre-MFA states or OTP reuse. Improper remember-device configuration can create bypass paths that undermine step-up authentication enforcement.
