How to Detect Magisk & Magisk Root in Android Apps Using AI
This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Detect Magisk, Magisk Manager, Zygisk and other Magisk modules in Android apps.
What Is Magisk?
Magisk is a powerful “systemless” rooting framework that allows attackers to gain full root access on Android devices by modifying the boot image instead of the system partition. This method bypasses traditional root detection and security controls by leaving core system files unchanged, enabling attackers to manipulate system behavior, load arbitrary modules, and gain unrestricted access to any apps and data. With Magisk installed, attackers can mount the data partition and directly access sensitive files—such as shared preferences containing session tokens or MFA flags—without triggering OS-level protections. These capabilities make it easy to hijack user sessions, replay secure transactions, or disable app-level defenses. Unlike OS remount attacks, Magisk operates in RAM, creating an ephemeral overlay that hides modifications and evades detection, posing a serious threat to Android app integrity, user privacy, and compliance with security frameworks like PCI DSS and NIST 800-53.
How Appdome Protects Mobile Apps Against Magisk
Appdome’s dynamic Detect Magisk plugin for Android detects Magisk-based rooting, including Magisk Manager, MagiskHide, and Magisk Modules, by identifying the presence of systemless root, injected modules, and Magisk’s patched boot sequence. This includes monitoring for signs of overlay-based execution, unauthorized access to app-private directories, and suspicious process behavior. Developers can use Threat-Events™ to capture Magisk-related detections in real time and design customized in-app responses to ensure compliance and user safety.
Prerequisites for Using Appdome's Detect Magisk Plugins:
To use Appdome’s mobile app security build system to Detect Magisk, Magisk Manager, Zygisk and other Magisk modules , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Detect Magisk
- Mobile App (.apk or .aab for Android)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
How to Implement Detect Magisk, Magisk Manager, Zygisk and other Magisk modules in Android Apps Using Appdome
On Appdome, follow these 3 simple steps to create self-defending Android Apps that Detect Magisk, Magisk Manager, Zygisk and other Magisk modules without an SDK or gateway:
-
Designate the Mobile App to be protected.
-
Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
-
Android Formats: .apk or .aab
-
Detect Magisk is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
-
-
Select the defense: Detect Magisk.
-
-
Follow the steps in Sections 2.2-2.2.2 of this article to add the Detect Magisk feature to your Fusion Set via the Appdome Console.
-
When you select the Detect Magisk you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Detect Magisk.
Figure 2: Fusion Set that displays the newly added Detect Magisk protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory). -
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):
Figure 3: Fusion Set Detail Summary
-
Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:
-
Refer to the Appdome API Reference Guide for API building instructions.
-
Look for sample APIs in Appdome’s GitHub Repository.
-
Create and name the Fusion Set (security template) that will contain the Detect Magisk feature as shown below:
Figure 1: Fusion Set that will contain the Detect Magisk feature
-
-
Add the Detect Magisk feature to your security template.
-
Navigate to Build > Anti Malware tab > Android Hacking Tool section in the Appdome Console.
-
Toggle On > Detect Magisk.
(a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Detect Magisk as shown below.
(b) To receive mobile Threat Monitoring, check the ThreatScope™ box as shown below. For more details, see our knowledge base article on ThreatScope™ Mobile XTM.
Figure 4: Selecting Detect Magisk, Magisk Manager, Zygisk and other Magisk modules
Note: The Appdome Platform displays the Mobile Operation Systems supported by each defense in real-time. For more details, see our OS Support Policy KB. -
Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Detect Magisk:
-
Threat-Events™ OFF > In-App Defense
If the Threat-Events™ setting is not selected. Appdome will detect and defend user and app by enforcing Detect Magisk.
-
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 Detect Magisk Intelligence and Control in Mobile Apps.
-
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 to 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 Detect Magisk Intelligence and Control in Mobile Apps.
-
-
Configure the User Experience Options for Detect Magisk:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.- App Compromise Notification: Customize the pop-up or toast Appdome uses to notify the user when a threat is present while using the protected mobile app.
- Short message Option. This is available for mobile devices that allow a banner notification for security events.
-
Localized Message Option. Allows Appdome users to support global languages in security notifications.

-
Detect Magisk Threat Code™. Appdome uses AI to generate a unique code each time Detect Magisk is triggered by an active threat on the mobile device. Use the code in Appdome Threat Resolution Center™ to help end users identify, find and resolve active threats on the personal mobile devices.
-
Congratulations! The Detect Magisk protection is now added to the mobile app -
-
Certify the Detect Magisk feature in Android Apps
After building Detect Magisk, Appdome generates a Certified Secure™ certificate to guarantee that the Detect Magisk protection has been added and is protecting the app. To verify that the Detect Magisk protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
Figure 6: 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 Detect Magisk has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Detect Magisk and other mobile app security features are in each build of the mobile app.

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.
Releasing and Publishing Mobile Apps with Detect Magisk
After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
- Customizing, Configuring & Branding Secure Mobile Apps.
- Deploying/Publishing Secure mobile apps to Public or Private app stores.
- Releasing Secured Android & iOS Apps built on Appdome.
