Detect Hooking Frameworks

Last updated September 5, 2023 by Appdome

Learn to Detect Hooking Frameworks in Android apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What are Hooking Frameworks?

Hooking frameworks are software tools or techniques that allow hackers to intercept and modify the behavior of Android applications or the operating system itself by inserting custom code or “hooks” into the code execution flow. These hooks can capture specific events or function calls, enabling hackers to monitor and alter the application’s functionality. While hooking frameworks have legitimate uses in debugging, testing, and performance monitoring, they can also be exploited for malicious purposes, posing significant security risks. When used maliciously, these frameworks can lead to unauthorized access, information theft, application tampering, and other potential threats, making them a concern in terms of Android security.

Why Should Detecting Hooking Frameworks be a Priority?

Detecting and defending against hooking frameworks is crucial to safeguard sensitive data, maintain application integrity, prevent unauthorized access, preserve user trust, and mitigate the spread of malware. By doing so, it contributes to creating a more secure and reliable Android environment, benefiting both developers and end users. Appdome employs multiple methods to detect and protect applications from Android Hooking Frameworks. This includes monitoring for any unauthorized changes made to the app’s binary function implementations and identifying malicious frameworks used within the app’s process’ memory. Through these proactive measures, Appdome ensures a robust defense against potential security threats posed by hooking frameworks in the Android ecosystem.


Detect Hooking Frameworks on Android apps using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Detect Hooking Frameworks 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. Detect Hooking Frameworks Compatible With: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and more
  2. Build the feature: Detect Hooking Frameworks.

    1. Building Detect Hooking Frameworks by using Appdome’s DEV-API:

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

        Figure 1: Fusion Set that will contain the Detect Hooking Frameworks 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 Detect Hooking Frameworks feature via Appdome Console, to add the Detect Hooking Frameworks 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, Cirlce 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 Detect Hooking Frameworks feature via Appdome Console

      To build the Detect Hooking Frameworks 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: Toggle (turn ON) Detect Hooking Frameworks, 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 Detects Hooking Frameworks. Detect Hooking Frameworks option

        Figure 3: Detect Hooking Frameworks 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 Detect Hooking Frameworks you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Detect Hooking Frameworks

        Fusion Set applied Detect Hooking Frameworks

        Figure 4: Fusion Set that displays the newly added Detect Hooking Frameworks protection

      4. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Detect Hooking Frameworks:
        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 Detect Hooking Frameworks.

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

          When this setting is used, Appdome detects Hooking Frameworks 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 Hooking Frameworks Intelligence and Control in Mobile Apps.

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

          When this setting is used, Appdome detects and defends against Hooking Frameworks (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 Detect Hooking Frameworks Intelligence and Control in Mobile Apps.

      5. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
    Congratulations!  The Detect Hooking Frameworks protection is now added to the mobile app
  3. Certify the Detect Hooking Frameworks feature in Android Apps.

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

Using Threat-Events™ for Hooking Frameworks Intelligence and Control in Android Apps
