Microsoft will enforce mandatory multi-factor authentication (MFA) for the Microsoft 365 admin center starting February 2025. All logins must pass an MFA challenge to enhance account security and prevent unauthorized access. This is a significant security enhancement aimed at mitigating the risk of account hijacking. The enforcement of MFA is a crucial step in bolstering the security posture of Microsoft 365 environments. It addresses the growing threat of credential theft and unauthorized access to sensitive administrative functions. By requiring MFA, Microsoft significantly raises the bar for attackers, making it harder for them to gain control of admin accounts.
Iranian hackers are targeting organizations with a sophisticated multi-factor authentication (MFA) push-bombing attack, aiming to compromise their Microsoft 365, Azure, and Citrix Systems accounts. This attack involves sending a barrage of MFA push notifications to a victim’s device, overwhelming them with authentication requests and potentially tricking them into approving a malicious login.
The attackers exploit the user’s trust in MFA and their desire to quickly clear the notifications. This attack highlights the importance of implementing robust MFA strategies, including the use of advanced MFA solutions and security awareness training for employees. Organizations should also be wary of suspicious activity related to MFA notifications and promptly investigate any unusual behavior.
