How to Detect iOS FaceID Keychain Exploits Using AI

Last updated April 22, 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 iOS FaceID Keychain Exploits in iOS apps.

What are iOS FaceID Keychain Exploits?

The Apple iOS FaceID Keychain Exploit targets the biometric authentication and secure keychain storage mechanisms on iOS devices. Attackers attempt to manipulate FaceID authentication workflows by intercepting or altering facial recognition data, injecting synthetic identities, or modifying keychain-stored credentials. Exploiting FaceID at the API or system level allows attackers to bypass authentication, gain unauthorized access to user accounts (account takeovers ATOs), and compromise sensitive data stored within the iOS Keychain. This is particularly dangerous for financial, healthcare, and enterprise applications that rely on FaceID for authentication and secure transactions. As AI-driven spoofing and biometric bypass techniques evolve, attackers can leverage deepfake models and software-based vulnerabilities to subvert FaceID protections, making real-time detection crucial.

How Appdome Protects Against iOS FaceID Keychain Exploits

Appdome’s Detect Apple iOS FaceID Keychain Exploit plugin monitors FaceID API calls and Keychain access for unauthorized modifications or tampering attempts to both outbound and inbound calls. It dynamically detects and blocks threats that seek to alter stored biometric authentication data, ensuring secure FaceID-based authentication.

Prerequisites for Using Appdome's Detect iOS FaceID Keychain Exploits Plugins:

To use Appdome’s mobile app security build system to Detect iOS FaceID Keychain Exploits , you’ll need:

How to Implement Detect iOS FaceID Keychain Exploits in iOS Apps Using Appdome

On Appdome, follow these simple steps to create self-defending iOS Apps that Detect iOS FaceID Keychain Exploits 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. iOS Formats: .ipa
    3. Detect iOS FaceID Keychain Exploits is compatible with: Obj-C, Java, Swift, Flutter, React Native, Unity, Xamarin, Cordova and other iOS apps.
  2. Select the defense: Detect iOS FaceID Keychain Exploits.

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

        Figure 1: Fusion Set that will contain the Detect iOS FaceID Keychain Exploits feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Detect iOS FaceID Keychain Exploits feature to your Fusion Set via the Appdome Console.

      3. When you enable Detect Face ID 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 iOS FaceID Keychain Exploits.

        Figure 2: Fusion Set that displays the newly added Detect iOS FaceID Keychain Exploits 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 iOS FaceID Keychain Exploits feature to your security template.

      1. Navigate to Build > Anti ATO tab > Deep Fake Detection section in the Appdome Console.
      2. Toggle On Detect Face ID Bypass > Detect iOS FaceID Keychain Exploits.
        Note: The checkmark feature Detect iOS FaceID Keychain Exploits is enabled by default, as shown below. Detect iOS FaceID Keychain Exploits option

        Figure 4: Selecting Detect iOS FaceID Keychain Exploits

    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 iOS FaceID Keychain Exploits protection is now added to the mobile app
  3. Certify the Detect iOS FaceID Keychain Exploits feature in iOS Apps

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

Using Threat-Events™ for iOS FaceID Keychain Exploits Intelligence and Control in iOS Apps

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

The specifications and options for Threat-Events™ for iOS FaceID Keychain Exploits are:
