Introduction:
With the rise of digital transformation and the cost-effectiveness of Azure AD Active Directory usage, many corporate entities are shifting towards Azure services. Azure’s hybrid technology introduces access control risks, particularly from On-Prem to Cloud infrastructure transitions. However, this transition isn’t straightforward; there exist multiple security risks that could lead to accessing the On-Prem Active Directory controller through a compromised cloud system. Additionally, logging into Azure AD via On-Prem Windows systems is also feasible. Attackers actively seek out such vulnerabilities to exploit, including those present in web applications hosted on Azure. Consequently, both On-Prem and on-cloud active directory infrastructures are vulnerable to exploitation.
In light of these risks, it is strongly recommended that organizations incorporate Azure AD into their penetration testing routines, regardless of their internal or external network configurations.
