Hackers Exploit ADFS to Bypass MFA and Access Critical Systems

Hackers are targeting organizations using Microsoft’s Active Directory Federation Services (ADFS) to bypass multi-factor authentication (MFA) and infiltrate critical systems.

Leveraging phishing techniques, these attackers deceive users with spoofed login pages, harvest credentials, and manipulate ADFS integrations to gain unauthorized access to sensitive data, posing a significant threat to organizational security.

The ADFS Vulnerability

Microsoft ADFS is a widely used tool for enabling single sign-on (SSO) by bridging authentication across multiple services, making it a cornerstone of many enterprises’ authentication systems.

However, security experts warn that ADFS, when not properly safeguarded, can become a gateway for hackers.

By exploiting the inherent trust-based environment of ADFS and crafting convincing phishing pages, attackers are bypassing MFA mechanisms and taking over user accounts.

This method is particularly effective against organizations lagging behind in adopting modern security protocols, as many still rely on legacy systems that are ill-equipped to counter advanced threats.
