Multi-factor authentication (MFA) can block up to 99.2% of account compromise attacks, yet many businesses underutilize or misconfigure it. The post covers the three authentication factor categories, business benefits, common adoption roadblocks (cost, usability, compliance), and real-world MFA bypass techniques observed by Huntress SOC analysts — including brute force on RDP, disabling Duo Security post-compromise, SIM swapping, push bombing, and AiTM attacks using tools like Evilginx. It also compares MFA types (SMS-based, app authenticators, hardware tokens, biometrics) and their trade-offs in security, cost, and manageability.
