How to Detect iOS AVCaptureSession Hijacking Using AI
This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Detect iOS AVCaptureSession Hijacking in iOS apps.
What is iOS AVCaptureSession Hijacking?
AVCaptureSession Hijacking is an attack where an iOS app’s real-time camera feed is replaced with manipulated video, such as deepfake renderings, to bypass biometric authentication or other security mechanisms. Attackers exploit vulnerabilities in the AVCaptureSession API to intercept and inject synthetic media, deceiving FaceID or other vision-based authentication systems. This technique enables unauthorized access, identity fraud, and session hijacking. Since deepfake technology continues to advance, preventing real-time camera feed manipulation is crucial for securing mobile applications that rely on facial recognition.
How Appdome Protects Against iOS AVCaptureSession Hijacking
Appdome’s Detect iOS AVCaptureSession Hijacking plugin dynamically monitors the iPhone’s AVCaptureSession API for unauthorized video feed substitutions. It detects deepfake renderings and blocks malicious attempts to inject synthetic media into authentication workflows, ensuring only genuine camera input is processed.
Prerequisites for Using Appdome's Detect iOS AVCaptureSession Hijacking Plugins:
To use Appdome’s mobile app security build system to Detect iOS AVCaptureSession Hijacking , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Detect iOS AVCaptureSession Hijacking
- Mobile App (.ipa for iOS)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
How to Implement Detect iOS AVCaptureSession Hijacking in iOS Apps Using Appdome

-
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:
-
Refer to the Appdome API Reference Guide for API building instructions.
-
Look for sample APIs in Appdome’s GitHub Repository.
-
Create and name the Fusion Set (security template) that will contain the Detect iOS AVCaptureSession Hijacking feature as shown below:Figure 1: Fusion Set that will contain the Detect iOS AVCaptureSession Hijacking feature
-
-
Add the Detect iOS AVCaptureSession Hijacking feature to your security template.
-
Navigate to Build > Anti ATO tab > Deep Fake Detection section in the Appdome Console.
-
Toggle On Detect Face ID Bypass > Detect iOS AVCaptureSession Hijacking.
Note: The checkmark feature Detect iOS AVCaptureSession Hijacking is enabled by default, as shown below.Figure 4: Selecting Detect iOS AVCaptureSession Hijacking
-
Congratulations! The Detect iOS AVCaptureSession Hijacking protection is now added to the mobile app -
-
Certify the Detect iOS AVCaptureSession Hijacking feature in iOS Apps
After building Detect iOS AVCaptureSession Hijacking, Appdome generates a Certified Secure™ certificate to guarantee that the Detect iOS AVCaptureSession Hijacking protection has been added and is protecting the app. To verify that the Detect iOS AVCaptureSession Hijacking protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
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 AVCaptureSession Hijacking has been added to each iOS app. Certified Secure provides instant and in-line DevSecOps compliance certification that Detect iOS AVCaptureSession Hijacking and other mobile app security features are in each build of the mobile app.
Using Threat-Events™ for iOS AVCaptureSession Hijacking Intelligence and Control in iOS Apps
Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when iOS AVCaptureSession Hijacking is detected. To consume and use Threat-Events™ for iOS AVCaptureSession Hijacking in iOS Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for iOS AVCaptureSession Hijacking shown below.
The specifications and options for Threat-Events™ for iOS AVCaptureSession Hijacking are:
Threat-Event™ Elements | Detect iOS AVCaptureSession Hijacking Method Detail |
