How to Detect Debug Breakpoints in Android & iOS Apps Using AI

Last updated February 9, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Detect Debug Breakpoints in Mobile apps.

What are Debug Breakpoints?

Debug breakpoints allow attackers to dynamically alter app behavior by attaching debuggers or injecting code at runtime. On iOS, Objective-C’s dynamic nature is exploited to overwrite methods, redirect messages, or modify class variables, while on Android, dex file loading is used for code injection. These manipulations can bypass protections, tamper with operations, and expose sensitive data like encryption keys or credentials. With AI automating such attacks, runtime security becomes critical for maintaining data integrity, confidentiality, and compliance with standards like SOX and HIPAA in health and financial apps.

How Appdome Protects Against Debug Breakpoints?

Appdome’s dynamic Detect Debug Breakpoints plugin for Android and iOS blocks debugger-based code manipulations at runtime. It monitors app execution to identify suspicious activities like method overwrites, class injections, or variable tampering. Upon detecting debugger manipulations, the plugin prevents attackers from bypassing security controls, protecting sensitive data and ensuring app integrity in real time. Mobile developers can use Appdome’s Threat-Events™ to gather data on debug breakpoints events and create a customized user experience when such threats are detected, enhancing both security and user awareness.

Prerequisites for Using Appdome's Detect Debug Breakpoints Plugins:

To use Appdome’s mobile app security build system to Detect Debug Breakpoints , you’ll need:

How to Implement Detect Debug Breakpoints in Mobile Apps Using Appdome

On Appdome, follow these simple steps to create self-defending Mobile Apps that Detect Debug Breakpoints 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. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
    3. Detect Debug Breakpoints is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
  2. Select the defense: Detect Debug Breakpoints.

      1. Create and name the Fusion Set (security template) that will contain the Detect Debug Breakpoints feature as shown below:
        fusion set that contains Detect Debug Breakpoints

        Figure 1: Fusion Set that will contain the Detect Debug Breakpoints feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Detect Debug Breakpoints feature to your Fusion Set via the Appdome Console.

      3. When you enable ONEShield™ by Appdome you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Detect Debug Breakpoints.

        Figure 2: Fusion Set that displays the newly added Detect Debug Breakpoints 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 Detect Debug Breakpoints feature to your security template.

      1. Navigate to Build > Security tab > ONEShield™ section in the Appdome Console.
      2. Toggle On ONEShield™ by Appdome > Detect Debug Breakpoints.
        Note: The checkmark feature Detect Debug Breakpoints is enabled by default, as shown below. Detect Debug Breakpoints option

        Figure 4: Selecting Detect Debug Breakpoints

        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 Detect Debug Breakpoints:
        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 Debug Breakpoints

        4. Detect Debug Breakpoints Threat Code™. Appdome uses AI/ML to generate a unique code each time Detect Debug Breakpoints 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 Detect Debug Breakpoints protection is now added to the mobile app
  3. Certify the Detect Debug Breakpoints feature in Mobile Apps

    After building Detect Debug Breakpoints, Appdome generates a Certified Secure™ certificate to guarantee that the Detect Debug Breakpoints protection has been added and is protecting the app. To verify that the Detect Debug Breakpoints protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: Detect Debug Breakpoints 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 Detect Debug Breakpoints has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Detect Debug Breakpoints and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Debug Breakpoints Intelligence and Control in Mobile Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Debug Breakpoints are detected. To consume and use Threat-Events™ for Debug Breakpoints in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for Debug Breakpoints shown below.

The specifications and options for Threat-Events™ for Debug Breakpoints are:

The following is a code sample for native Mobile apps, which uses all values in the specification above for Detect Debug Breakpoints:


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 Apps by using Detect Debug Breakpoints. 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.
