How to Block Magisk & Magisk Root in Android Apps

Last updated December 5, 2023 by Appdome

Learn to Block Magisk, Magisk Manager, Zygisk and other Magisk modules in Android apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is Magisk, Magisk Manager, Zygisk and other Magisk modules?

Magisk is a “systemless” Rooting tool that is used for elevating privileges to gain system-level access (root access) to the Android OS and underlying file system. Magisk does not make changes to the Android bootloader or require flashing custom ROM. Instead, it stores modifications in the boot partition rather than modify the real system files. Since the original system files remain unchanged, modifications can go undetected by Google SafetyNet and most root detection methods, which makes Magisk Manager an incredibly powerful and popular tool for compromising Android apps.

Magisk Manager is a rooting framework (like its predecessors SuperuserSU and Xposed) that provides multiple modules that enable different rooting features that exploit root access privileges in different ways.

Why Block Magisk, Magisk Manager, Zygisk and other Magisk modules in Android Apps?

All you need to do is have a short read of some of the posts from Magisk creator “topjohnwu” on this and many other threads to understand that Magisk is NOT a tool that you should take lightly. Bottom line, if someone other than the app developer is using Magisk on a rooted Android device that your app is also running on, your app is highly vulnerable to attack unless you have protections built into the app. 

Using Appdome, you can block Magisk, Magisk Manager, and Magisk Hide, Zygisk and all other modules and variants of Magisk to protect mobile apps from being compromised by cybercriminals using the Magisk framework.

In addition, Appdome can also Detect Advanced Malware Controls to identify advanced Magisk hiding techniques such as socket and module hiding.

Appdome Anti-Reversing protection along with Anti-Tampering and Anti-Debugging defend any mobile app against tampering, malicious debugging. and reverse engineering, acting as a solid first line of defense. Appdome’s Block Magisk Manager is designed to complement, reinforce, and build upon these other features and defend against experienced cybercriminals using specialized tools.

Prerequisites for Using Block Magisk:

To use Appdome’s mobile app security build system to Block Magisk, Magisk Manager, Zygisk and other Magisk modules , you’ll need:

Block Magisk, Magisk Manager, Zygisk and other Magisk modules on Android apps using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Block Magisk, Magisk Manager, Zygisk and other Magisk modules 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 Compatible With: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps
  2. Build the feature: Block Magisk.

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

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

        Figure 1: Fusion Set that will contain the Block Magisk 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 feature via Appdome Console, to add the Block Magisk 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, as shown in Figure 1 above, and get 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 feature via Appdome Console

      To build the Block Magisk 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. When you select the Block Magisk 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

        Fusion Set applied Block Magisk

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

      3. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Block Magisk:
        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 Block Magisk, Magisk Manager, Zygisk and other Magisk modules.

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

          When this setting is used, Appdome detects Magisk manager, Zygist or other Magisk modules 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 Intelligence and Control in Mobile Apps.

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

          When this setting is used, Appdome detects and defends against Magisk, Magisk Manager, Zygisk and other Magisk modules (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 Intelligence and Control in Mobile Apps.

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