New Video from @BlackHatOfficialYT: In-Depth Analysis of Microsoft Intune by Cybersecurity Expert Y Chudo

In this video, Y Chudo, a cybersecurity expert working for SEC Works, presents an in-depth analysis of Microsoft Intune, a widely used endpoint management solution in enterprises. He explores the features of Intune, its internal mechanisms, and potential attack techniques that can be exploited by hackers. Y Chudo begins by explaining what Microsoft Intune is and its crucial role in device management within enterprises. Intune is an endpoint management solution that offers features such as configuration management, application deployment, and more.

He highlights that many companies use Active Directory and Group Policy for device management, but increasingly, companies are adopting Azure AD and Microsoft Intune due to their numerous features. The presentation focuses on two main components of Microsoft Intune: device enrollment and device management. Y Chudo details the device enrollment process, which starts with installing the Intune Company Portal application on a smartphone. The application then asks users to log in with their Azure AD credentials.

Once logged in, the application receives an access token used to discover the enrollment server and register the device in Intune. This process involves exchanging certificates and access tokens to authenticate and manage devices. Y Chudo then moves on to device management, explaining how Intune uses the OMA-DM protocol to communicate with enrolled devices. This protocol allows Intune to configure device settings, deploy applications, and manage various aspects of device configuration. He shows how DM commands are used to send instructions to devices and receive responses containing the results of the requested actions.

The most interesting part of the presentation concerns potential attack techniques against Microsoft Intune. Y Chudo presents four attack techniques, two related to the enrollment process and two related to the management process. The first technique involves bypassing conditional access policies by using the Intune Company Portal application to obtain access tokens, even if the device is not compliant. This allows attackers to access sensitive cloud resources without adhering to security policies.

Another attack technique involves deleting device objects by exploiting differences in enrollment requests between platforms. Y Chudo shows how an attacker can send an enrollment request with another device's ID, resulting in the deletion of the existing device object in Intune. This can make the device inaccessible and unmanageable by administrators. Y Chudo also addresses attacks related to device management, including establishing an initial foothold by exploiting the OMA-DM protocol. He demonstrates how attackers can steal sensitive network configurations, such as VPN and Wi-Fi information, by mimicking the Intune application.

Additionally, he explains how attackers can impersonate an Autopilot device to obtain Active Directory computer account credentials. To illustrate these techniques, Y Chudo introduces a new tool called Pyune, which can execute the attacks described in the presentation. He demonstrates how Pyune can enroll a fake device, communicate with Intune, and steal sensitive network configurations and applications. In conclusion, Y Chudo recommends reviewing and strengthening security configurations, such as conditional access policies and device enrollment settings, to make attacks more difficult. He emphasizes the importance of blocking the enrollment of unauthorized devices and protecting credentials against phishing.
