You can detect MFA bypass vulnerabilities using automated scripts to identify patterns like OTP brute-force, OTP replay, and direct navigation to post-login URLs. This approach evaluates the entire attack chain, including race conditions and device trust escalation.

Common 2FA bypass patterns include no rate limit on OTP, OTP replay, direct navigation to post-login URLs, brute-force OTP, recovery code exploitation, race conditions, and device trust escalation. These vulnerabilities allow unauthorized access by circumventing multi-factor authentication mechanisms.

Yes, testing for MFA bypass vulnerabilities requires tools like Burp Suite and ffuf. These dependencies are necessary for intercepting web traffic, automating requests, and running scripts for automated testing and verification of the identified bypass patterns.

To exploit race conditions and recovery codes during a 2FA bypass audit, this Skill analyzes the authentication attack chain. It verifies if simultaneous OTP requests or recovery code reuse can successfully grant unauthorized access to the target web application.

Yes, you can audit device trust escalation in authentication mechanisms. The Skill detects and analyzes device trust escalation patterns alongside OTP brute-force and direct navigation bypass to ensure robust security defenses against MFA bypass attacks.

Automated scripts for MFA bypass detection are limited by their reliance on predefined patterns like OTP replay and direct navigation. They require tools like Burp Suite for traffic interception and may not identify novel bypass techniques outside the seven specific patterns evaluated.
