How to Detect SSL Pinning Bypass in Android Apps Using AI

Last updated October 23, 2025 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Detect SSL Pinning Bypass in Android apps.

What Are SSL Pinning Bypass Attacks?

An SSL Pinning Bypass attack occurs when attackers disable or bypass certificate validation, allowing them to intercept and manipulate encrypted communications between a mobile app and its server. Exploiting weaknesses in SSL pinning implementations, attackers use tools like mitmproxy or Objection to bypass these checks, tricking the app into trusting a malicious server certificate and modifying network traffic to replace legitimate certificates. This enables Man-in-the-Middle (MitM) attacks, where sensitive data like login credentials, API calls, or transactions are intercepted or altered. As AI-based malware advances, automated SSL Pinning Bypass attacks could make real-time detection and defense increasingly challenging. Defending against these bypass attacks is critical for compliance with standards such as PCI DSS and GDPR, which require secure communications.

How Appdome Protects Mobile Apps Against SSL Pinning Bypass Attacks?

Appdome’s dynamic Detect SSL Pinning Bypass plugin for Android defends against attacks that bypass SSL/TLS certificate pinning, exposing sensitive app data to man-in-the-middle (MitM) attacks. The plugin continuously monitors the app’s network communication to detect tools like Frida, Xposed, HttpCanary, and SSLUnpinning modules that intercept or alter secure traffic. It identifies suspicious behaviors such as unauthorized certificate injections, custom CA installations, or tampered network libraries. It triggers responses such as alerting the app or backend to terminate unsafe sessions. Mobile developers can leverage Appdome’s Threat-Events™ to collect detailed data on SSL pinning bypass events and tailor in-app responses based on detected threats.

Prerequisites for Using Appdome's Detect SSL Pinning Bypass Plugins:

To use Appdome’s mobile app security build system to Detect SSL Pinning Bypass , you’ll need:

How to Implement Detect SSL Pinning Bypass in Android Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Detect SSL Pinning Bypass 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. Detect SSL Pinning Bypass is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
  2. Select the defense: Detect SSL Pinning Bypass.

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

        Figure 1: Fusion Set that will contain the Detect SSL Pinning Bypass feature

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

      3. When you select the Detect SSL Pinning Bypass you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Detect SSL Pinning Bypass.

        Fusion Set applied Detect SSL Pinning Bypass

        Figure 2: Fusion Set that displays the newly added Detect SSL Pinning Bypass 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 SSL Pinning Bypass feature to your security template.

      1. Navigate to Build > Anti Malware tab > Android Hacking Tool section in the Appdome Console.
      2. Toggle On > Detect SSL Pinning Bypass.

        (a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Detect SSL Pinning Bypass 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.
        Detect SSL Pinning Bypass option

        Figure 4: Selecting Detect SSL Pinning Bypass

        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. Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Detect SSL Pinning Bypass:
        1. 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 SSL Pinning Bypass.

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

          When this setting is used, Appdome detects an SSL Bypass Pinning attack 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 SSL Pinning Bypass Intelligence and Control in Mobile Apps.

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

          When this setting is used, Appdome detects and defends against SSL Pinning Bypass (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 SSL Pinning Bypass Intelligence and Control in Mobile Apps.

      4. Configure the User Experience Options for Detect SSL Pinning Bypass:
        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 SSL Pinning Bypass

        4. Detect SSL Pinning Bypass Threat Code™. Appdome uses AI to generate a unique code each time Detect SSL Pinning Bypass 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 SSL Pinning Bypass protection is now added to the mobile app
  3. Certify the Detect SSL Pinning Bypass feature in Android Apps

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

Using Threat-Events™ for SSL Pinning Bypass Intelligence and Control in Android Apps

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