It outlines the most common attack methods used by cybercriminals and the practical steps businesses can take to strengthen their defences. **Common MFA bypass techniques include:** - Phishing and social engineering attacks - MFA fatigue attacks (rapid-fire push requests) - Man-in-the-middle (MitM) attacks that intercept credentials - Session hijacking and token theft - Exploiting legacy authentication protocols **Mitigation strategies covered:** - Implementing phishing-resistant MFA methods (e.g. FIDO2, hardware tokens) - Blocking legacy protocols that weaken security - Applying conditional access policies - Monitoring for abnormal login behaviours - Educating users about social engineering tactics This guide is ideal for IT teams, security leads, and business owners looking to strengthen access controls and understand the limits of traditional MFA.
