8 Things to Avoid in Azure Active Directory: A Guide to Secure Your Infrastructure


Azure Active Directory (Azure AD) offers a centralized solution for managing digital identities and simplifying IT infrastructure. However, it’s important to note that the default configuration of Azure AD includes basic features and security settings. This leaves organizations vulnerable to potential data leaks, unauthorized access, and targeted cyberattacks.

One example of such vulnerability is the default setting for Azure storage accounts, which allows access from anywhere, including the internet. This can introduce significant security risks if not properly addressed.

A critical aspect of securing Azure AD is protecting against attacks on Azure AD Connect. Cybercriminals can exploit this service, which synchronizes Azure AD with Windows AD servers, to decrypt user passwords and compromise administrator accounts. Once inside the system, attackers have the potential to access and encrypt an organization’s most sensitive data, leading to severe consequences.

Neglecting to enforce multi-factor authentication (MFA) creates an opportunity for attackers to easily connect a malicious device to an organization using compromised account credentials. Implementing MFA for all users joining the Active Directory with a device is a commonly overlooked security measure.

In addition to increased security risks, a poorly configured Azure AD can also result in process bottlenecks and poor system performance. It is crucial to ensure proper configuration to maintain smooth operations and optimize efficiency.

Production Tenants Used for Tests:

Using production tenants for testing purposes is a common mistake. We recommend creating separate tenants dedicated to testing new apps and settings. By minimizing the exposure of Personally Identifiable Information (PII) in these testing environments, you can mitigate potential risks.

Overpopulated Global Admins:

Assigning the Global Admin role to user accounts grants unlimited control over your Azure AD tenant and, in some cases, your on-premises AD forest. To reduce risks, consider using less privileged roles for delegation of permissions. For example, the Security Reader or Global Reader role can be sufficient for security auditors.

Not Enforcing Multi-Factor Authentication (MFA):

Failure to enforce MFA for all users joining the Active Directory with a device can lead to security breaches. Temporary MFA exclusions should not become permanent, and trusted IP address ranges should be carefully configured. Leveraging Azure AD’s Security Defaults or configuring Global Administrators for continuous MFA usage can significantly enhance security.

Overprivileged Applications:


Applications registered in Azure AD often have stronger privileges than necessary. Regularly audit registered applications and service principals to prevent privilege escalation and potential misuse by malicious actors.

Fire-and-Forget Approach to Configuration:

Azure AD is continuously evolving, introducing new security features. Ensure that these features are enabled and properly configured, treating Azure AD deployment as an ongoing process rather than a one-time operation.

Insecure Azure AD Connect Servers:

Azure AD Connect servers, responsible for synchronizing Azure AD with on-premises AD, can be targeted by hackers. Consider them as Tier 0 resources and limit administrative rights to only Domain Admins.

Lack of Monitoring:

Default user activity logs in Azure AD are stored for only 30 days. Implement custom retention policies, leverage Azure Log Analytics, Unified Audit Log, or third-party SIEM solutions to monitor user activity and detect anomalies effectively.

Default Settings:

Default settings in Azure AD may not provide the highest level of security. Review and adjust settings such as third-party application registration, passwordless authentication methods, and ADFS endpoints to align with your organizational security policies.



Securing Azure Active Directory is essential to protect your infrastructure from data breaches and cyberattacks. By avoiding these eight common misconfigurations, you can significantly enhance the security posture of your Azure AD environment. Regularly assess and monitor your configuration, stay up-to-date with Azure AD’s evolving features, and adopt a proactive approach to maintain a robust security framework. Safeguard your organization’s digital identities with a well-configured Azure Active Directory.

Account Takeover Flaw In Azure AD Fixed By Microsoft

Account takeover flaw in Azure AD fixed by Microsoft

Microsoft has addressed an authentication flaw in Azure Active Directory (Azure AD) that could allow threat actors to escalate privileges and potentially fully take over the target’s account. The flaw, named nOAuth by the Descope security team, involved a misconfiguration that could be abused in account and privilege escalation attacks against Azure AD OAuth applications.

The attack method relied on the vulnerable applications using the email claim from access tokens for authorization. The attacker would modify the email on their Azure AD admin account to match the victim’s email address. Then, by using the “Log in with Microsoft” feature, they could gain authorization on the targeted app or website.

The impact of this vulnerability was significant. If the targeted resources allowed the use of email addresses as unique identifiers during the authorization process, the attacker could take complete control over the victim’s account. It was even possible to exploit this flaw when the victim did not have a Microsoft account.

This flaw was possible because Azure AD did not require validation for email changes. However, Microsoft has now fixed the issue to prevent further account takeovers and protect users from this form of privilege escalation.

Descope, the security team, has highlighted that if an app merges user accounts without validation, the attacker gains full control over the victim’s account, regardless of whether the victim has a Microsoft account.

After successfully logging in, the attacker has various options depending on the app or site they have taken over. They can establish persistence, exfiltrate data, explore possibilities for lateral movement, and more.

Descope linked several large organizations, including a design app with millions of frequent users, a publicly traded client experience establishment, and a leading multi-cloud consulting provider, that were set up to be vulnerable to this attack.

Descope has also shared a video detailing the exploitation of this Azure Active Directory (AAD) authentication misconfiguration, showcasing how it can result in a complete account takeover. The video also provides information on preventive measures to mitigate this vulnerability.

On April 11, 2023, Descope reported an initial finding to Microsoft regarding the nOAuth configuration. Today, Microsoft has issued mitigations to address the issue.

Redmond confirmed that several multi-tenant applications had users utilizing email addresses with unverified domain owners. However, if developers did not receive a notification, it indicated that their application did not consume email claims with unverified domain owners.

To safeguard customers and applications vulnerable to privilege escalation, Microsoft has implemented mitigations. These mitigations involve excluding token claims from unverified domain owners for most applications.

Microsoft strongly advised developers to conduct a comprehensive assessment of their app’s authorization business logic and adhere to the provided guidelines to prevent unauthorized access.

Furthermore, developers were encouraged to adopt the recommended best practices for token validation when utilizing the Microsoft identity platform.
