Vulnerabilities in Multi-Factor Authentication

This chapter explores the vulnerabilities in cross-origin resource sharing (CORS) and Multi-Factor Authentication (MFA) systems, detailing how attackers can exploit these weaknesses to impersonate users. It highlights real-world security failures, including a lapse in Microsoft's Azure MFA, and emphasizes the need for stricter security measures and external penetration testing. The episode advocates for a multifaceted approach to user authentication, underscoring that MFA is just one aspect of a comprehensive security strategy.
