How to Protect Android Apps With Block USB Debugging Using AI

Last updated July 13, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Block USB Debugging in Android apps.

What is USB Debugging?

USB Debugging is a developer tool that enables direct device-to-PC communication using Android Debug Bridge (ADB), allowing shell command execution, app installation, log access, and full file system visibility. While useful for debugging, in production environments it becomes a serious security risk. Attackers can use USB Debugging to bypass app controls, inject commands, extract sensitive data, tamper with app logic, or automate fraud workflows. USB Debugging is often used in rooting, malware deployment, and reverse engineering attacks. Since it operates at a low device level and leverages trusted system permissions, detecting and blocking USB Debugging from within the app is difficult. To be aligned with PCI DSS and similar compliance frameworks, apps should block USB Debugging in production to prevent unauthorized system access and data leakage. 

How Appdome Protects Android Apps Against USB Debugging

Appdome’s dynamic Block USB Debugging plugin for Android apps detects and blocks active USB debugging sessions at runtime, preventing ADB commands from executing over USB. Mobile developers can use Appdome’s Threat-Events™ to monitor USB Debugging attempts and build custom in-app responses when these threats are detected.

Prerequisites for Using Appdome's Block USB Debugging Plugins:

To use Appdome’s mobile app security build system to Block USB Debugging , you’ll need:

How to Implement Block USB Debugging in Android Apps Using Appdome

On Appdome, follow these simple steps to create self-defending Android Apps that Block USB Debugging without an SDK or gateway:

  1. Designate the Mobile App to be protected.

    1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.

    2. Android Formats: .apk or .aab
    3. Block USB Debugging is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
  2. Select the defense: Block USB Debugging.

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

        Figure 1: Fusion Set that will contain the Block USB Debugging feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Block USB Debugging feature to your Fusion Set via the Appdome Console.

      3. When you enable Detect Android Debug Bridge (ADB) you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Block USB Debugging.

        Figure 2: Fusion Set that displays the newly added Block USB Debugging protection
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      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 3: Fusion Set Detail Summary

      5. 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:
        1. Refer to the Appdome API Reference Guide for API building instructions.
        2. Look for sample APIs in Appdome’s GitHub Repository.
    1. Add the Block USB Debugging feature to your security template.

      1. Navigate to Build > Anti Fraud tab > Mobile Fraud Detection section in the Appdome Console.
      2. Toggle On Detect Android Debug Bridge (ADB) > Block USB Debugging.
        Note: The checkmark feature Block USB Debugging is enabled by default, as shown below. Block USB Debugging option

        Figure 4: Selecting Block USB Debugging

        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.

      3. Configure the User Experience Options for Block USB Debugging:
        With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.
        1. 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.
        2. Short message Option. This is available for mobile devices that allow a banner notification for security events.
        3. Localized Message Option. Allows Appdome users to support global languages in security notifications.

          Localized Message

          Figure 5: Default User Experience Options for Appdome’s USB Debugging

        4. Block USB Debugging Threat Code™. Appdome uses AI to generate a unique code each time Block USB Debugging 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.
    2. Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.
    Congratulations!  The Block USB Debugging protection is now added to the mobile app
  3. Certify the Block USB Debugging feature in Android Apps

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

    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 Block USB Debugging has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Block USB Debugging and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for USB Debugging Intelligence and Control in Android Apps

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

The specifications and options for Threat-Events™ for USB Debugging are:

Threat-Event™ Elements Block USB Debugging Method Detail
Appdome Feature Name Block USB Debugging
Threat-Event Mode
OFF, IN-APP DEFENSE Appdome detects, defends and notifies user (standard OS dialog) using customizable messaging.
ON, IN-APP DETECTION Appdome detects the attack or threat and passes the event in a standard format to the app for processing (app chooses how and when to enforce).
ON, IN-APP DEFENSE Uses Appdome Enforce mode for any attack or threat and passes the event in a standard format to the app for processing (gather intel on attacks and threats without losing any protection).

With Threat-Events™ enabled (turned ON), Android developers can get detailed attack intelligence and granular defense control in Android applications and create amazing user experiences for all mobile end users when USB Debugging is detected.


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


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 USB Debugging. 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.

Device Binding in the Age of AI

For years, fraud prevention solutions have tried to use Device IDs to bind (or link) a user’s account or session to a specific device to prevent unauthorized access from other devices. However, until recently, Device IDs lacked persistence and the broad threat context needed to stop fraud and ATOs …
