How to Detect Video Injection Attacks in iOS Apps Using AI

Last updated March 29, 2026 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Detect Video Injection Attacks in iOS apps.

What is a Video Injection Attack?

A Video Injection Attack occurs when an attacker intercepts or replaces the legitimate video stream fed into a facial recognition system with a fabricated or pre-recorded stream.

This is typically achieved by overwriting the frame buffer or injecting a synthetic video stream at the OS or driver level, effectively bypassing live camera input. These attacks are used to spoof identity, defeat liveness detection, and gain unauthorized access to face-based authentication systems.

How Appdome Detects Video Injection Attacks in iOS Apps?

Appdome detects video injection attacks in iOS apps by validating the integrity of camera sessions at runtime during the authentication flow, ensuring that video input cannot be injected, altered, or replaced by unauthorized sources.

The system verifies that video frames originate from a genuine hardware camera, monitors frame consistency throughout the capture process, and analyzes metadata for anomalies that may indicate tampering. It also detects irregularities in how frames are delivered and processed within the app.

By combining real-time camera session validation with anomaly detection in the video stream, Appdome ensures that only authentic, unmodified video input is used in face recognition decisions.

Prerequisites for Using Appdome's Detect Video Injection Attack Plugins:

How to Implement Detect Video Injection Attacks in iOS Apps Using Appdome

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

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

        Figure 1: Fusion Set that will contain the Detect Video Injection Attack feature

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

      3. When you enable Deepfake Video Detection you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Detect Video Injection Attack.

        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 Video Injection Attack:
        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 Video Injection Attack.

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

          When this setting is used, Appdome detects Video Injection Attacks 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 Video Injection Attack Intelligence and Control in Mobile Apps.

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

          When this setting is used, Appdome detects and defends against Video Injection Attacks (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 Video Injection Attack Intelligence and Control in Mobile Apps.

      4. Configure the User Experience Options for Detect Video Injection Attack:
        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.
