SANS Researchers Expose Massive Entra ID Password Spray Campaign

Security researchers at SANS Internet Storm Center have documented widespread password spray attacks targeting Microsoft Entra ID (formerly Azure AD) environments, with attackers systematically attempting authentication against multiple user accounts using common passwords. The attacks, detected through PowerShell-based log analysis of Entra ID audit logs, showed attackers leveraging rotating proxy services to evade IP-based blocking while targeting organizations that had migrated to cloud services but failed to implement proper monitoring. Multiple organizations were found to have inadequate conditional access policies, allowing attackers to probe authentication systems from unexpected geographic locations and compromise accounts through credential stuffing techniques. This incident highlights the critical gap many organizations face when transitioning to cloud infrastructure - abandoning the rigorous log monitoring practices they maintained for on-premises systems, creating blind spots that attackers actively exploit through automated credential attacks.
