How to Detect Magisk Hide in Android Apps

Last updated November 27, 2023 by Appdome

Learn to Prevent Magisk Hide in Android apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is Magisk Hide?

Magisk Hide hides root permissions for selected apps, allowing them to run with root access while hiding that your device is rooted. Starting from Magisk version 24, Magisk Hide is replaced by Zygisk, which hides the root through the DenyList feature.

Why Prevent Magisk Hide in Android Apps?

Magisk enables root privileges status for other, more advanced tools such as hex editors and dynamic code injection frameworks like Frida. In addition, Magisk can be used for injecting malware by turning on the Allow Unknown Sources setting. When this setting is enabled, the mobile device allows installing applications from any developers, publisher or source outside of the Google Play store. This is an extremely high level of trust, which would not have been given otherwise. And if a root cloaking feature such as Magisk Hide or Zygisk, which is part of Magisk Manager, is enabled, both the rooted status of the device and the applications that are using (or abusing) root access are concealed. This makes detecting root device much harder.

Prerequisites for Using Block Magisk Hide:

To use Appdome’s mobile app security build system to Prevent Magisk Hide , you’ll need:

Prevent Magisk Hide on Android apps using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Prevent Magisk Hide without an SDK or gateway:

  1. Upload the Mobile App to Appdome.

    1. Upload an app to Appdome’s Mobile App Security Build System

    2. Upload Method: Appdome Console or DEV-API
    3. Android Formats: .apk or .aab
    4. Block Magisk Hide Compatible With: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps
  2. Build the feature: Block Magisk Hide.

    1. Building Block Magisk Hide by using Appdome’s DEV-API:

      1. Create and name the Fusion Set (security template) that will contain the Block Magisk Hide feature as shown below:
      2. fusion set that contains Block Magisk Hide

        Figure 1: Fusion Set that will contain the Block Magisk Hide feature
        Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).

      3. Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Block Magisk Hide feature via Appdome Console, to add the Block Magisk Hide feature to this Fusion Set.

      4. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below): fusion Set Detail Summary image

        Figure 2: Fusion Set Detail Summary
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Circle CI or other system:
        1. Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
        2. Look for sample APIs in Appdome’s GitHub Repository
    2. Building the Block Magisk Hide feature via Appdome Console

      To build the Block Magisk Hide protection by using Appdome Console, follow the instructions below.

      1. Where: Inside the Appdome Console, go to Build > Anti Fraud Tab > Mobile Malware Prevention section.
      2. How: Check whether is toggled On (enabled), otherwise enable it . The feature Block Magisk Hide is enabled by default, as shown below. Toggle (turn ON) Block Magisk Hide, as shown below.
        If needed, Customize the Threat Notification to be displayed to the mobile end-user in a standard OS dialog notification when Appdome Prevents Magisk Hide.
        Block Magisk Hide option

        Figure 3: Prevent Magisk Hide option
        Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

      3. When you select the Block Magisk Hide you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Block Magisk Hide

        Fusion Set applied Block Magisk Hide

        Figure 4: Fusion Set that displays the newly added Block Magisk Hide protection

      4. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Block Magisk Hide:
        1. Threat-Events™ OFF > In-App Defense

          If the Threat-Events™ setting is cleared (not selected). Appdome will detect and defend the user and app by enforcing Prevent Magisk Hide.

        2. Threat-Events™ ON > In-App Detection

          When this setting is used, Appdome detects Magisk Hide and passes Appdome’s Threat-Event™ attack intelligence to the app’s business logic for processing, enforcement, and user notification. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Block Magisk Hide Intelligence and Control in Mobile Apps.

        3. Threat-Events™ ON > In-App Defense

          When this setting is used, Appdome detects and defends against Magisk Hide (same as Appdome Enforce) and passes Appdome’s Threat-Event™ attack intelligence the app’s business logic for processing. For more information on consuming and using Appdome Threat-Events™ in the app, see section Using Threat-Events™ for Block Magisk Hide Intelligence and Control in Mobile Apps.

      5. Optional Configuration with Block Magisk Hide:
        1. Block Magisk Hide

          Detects and blocks Magisk Hide, a feature that hides root permissions for selected apps, allowing them to run with root access while hiding that your device is rooted.

        2. Block Zygisk

          Detects and blocks Zygisk, a feature that replaced Magisk Hide in v.24. Zygisk provides better capabilities of hiding root permissions from Banking Apps and hides the root before Apps start to process after booting the device.

      6. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
    Congratulations!  The Block Magisk Hide protection is now added to the mobile app
  3. Certify the Block Magisk Hide feature in Android Apps

    After building Block Magisk Hide, Appdome generates a Certified Secure™ certificate to guarantee that the Block Magisk Hide protection has been added and is protecting the app. To verify that the Block Magisk Hide protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Block Magisk Hide shown in Certificate secure

    Figure 5: Certified Secure™ certificate

    Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Block Magisk Hide has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Block Magisk Hide and other mobile app security features are in each build of the mobile app

Using Threat-Events™ for Magisk Hide Intelligence and Control in Android Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Magisk Hide is detected. To consume and use Threat-Events™ for Magisk Hide in Android Apps, use registerReceiver in the Application OnCreate, and the code samples for Threat-Events™ for Magisk Hide shown below.

The following is a code sample for native Android apps, which uses all values in the specification above for Block Magisk Hide:


Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.



Using Appdome, there are no development or coding prerequisites to build secured Android Apps by using Block Magisk Hide. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
