How to Block AirPlay Using AI
This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Block AirPlay in iOS apps.
Block AirPlay?
Block AirPlay is a mobile app protection that prevents iOS apps from being mirrored to external AirPlay-compatible devices. Attackers and malicious tools can exploit AirPlay mirroring to visually capture sensitive app content such as personal data, credentials, or transaction details. Because AirPlay mirrors the display in real time, it poses a major data exfiltration risk—especially in regulated industries like finance, healthcare, and enterprise apps. Traditional DLP tools often miss this channel since it’s OS-native and doesn’t trigger alerts. Blocking AirPlay is essential to prevent visual leaks, enforce data protection, and maintain compliance with standards like GDPR and HIPAA.
How Appdome Protects iOS Apps With Block AirPlay
Appdome’s dynamic Block AirPlay plugin monitors iOS runtime for unauthorized attempts to initiate screen mirroring through AirPlay and blocks the session before any visual content is shared. It ensures app screens cannot be streamed to unauthorized displays, preserving app confidentiality and integrity. This protection can be enabled on Appdome by first enabling the “Block Screensharing Scams and Malware” protection, and then turning on the toggle switch for “Block AirPlay”
Prerequisites for Using Appdome's Prevent Screen Sharing Scams & Malware > Block AirPlay Plugins:
To use Appdome’s mobile app security build system to Block AirPlay , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Prevent Screen Sharing Scams & Malware > Block AirPlay
- Mobile App (.ipa for iOS)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
How to Implement Block AirPlay in iOS Apps Using Appdome
On Appdome, follow these 3 simple steps to create self-defending iOS Apps that Block AirPlay without an SDK or gateway:
-
Designate the Mobile App to be protected.
-
Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
-
iOS Formats: .ipa
-
Prevent Screen Sharing Scams & Malware > Block AirPlay is compatible with: Obj-C, Java, Swift, Flutter, React Native, Unity, Xamarin, Cordova and other iOS apps.
-
-
Select the defense: Prevent Screen Sharing Scams & Malware > Block AirPlay.
-
-
Follow the steps in Sections 2.2-2.2.2 of this article to add the Prevent Screen Sharing Scams & Malware > Block AirPlay feature to your Fusion Set via the Appdome Console.
-
When you select the Prevent Screen Sharing Scams & Malware > Block AirPlay you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Prevent Screen Sharing Scams & Malware > Block AirPlay.
Figure 2: Fusion Set that displays the newly added Prevent Screen Sharing Scams & Malware > Block AirPlay protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory). -
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):

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 Prevent Screen Sharing Scams & Malware > Block AirPlay feature as shown below:Figure 1: Fusion Set that will contain the Prevent Screen Sharing Scams & Malware > Block AirPlay feature
-
-
Add the Prevent Screen Sharing Scams & Malware > Block AirPlay feature to your security template.
-
Navigate to Build > Anti ATO tab > Social Engineering Prevention section in the Appdome Console.
-
Toggle On > Prevent Screen Sharing Scams & Malware > Block AirPlay.
(a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Prevent Screen Sharing Scams & Malware > Block AirPlay 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.Figure 4: Selecting Block AirPlay
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. -
Select the Threat-Event™ in-app mobile Threat Defense and Intelligence policy for Prevent Screen Sharing Scams & Malware > Block AirPlay:
-
Threat-Events™ OFF > In-App Defense
If the Threat-Events™ setting is not selected. Appdome will detect and defend user and app by enforcing Prevent Screen Sharing Scams & Malware > Block AirPlay.
-
Threat-Events™ ON > In-App Detection
When this setting is used, Appdome detects unauthorized screensharing abuse 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 Block Prevent Screen Sharing Scams & Malware > Block AirPlay Intelligence and Control in Mobile Apps.
-
Threat-Events™ ON > In-App Defense
When this setting is used, Appdome detects and defends against AirPlay (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 Block Prevent Screen Sharing Scams & Malware > Block AirPlay Intelligence and Control in Mobile Apps.

Configure the User Experience Options for Prevent Screen Sharing Scams & Malware > Block AirPlay:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.- 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.
- Short message Option. This is available for mobile devices that allow a banner notification for security events.
-
Localized Message Option. Allows Appdome users to support global languages in security notifications.

Prevent Screen Sharing Scams & Malware > Block AirPlay Threat Code™. Appdome uses AI/ML to generate a unique code each time Prevent Screen Sharing Scams & Malware > Block AirPlay 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.
-
Congratulations! The Prevent Screen Sharing Scams & Malware > Block AirPlay protection is now added to the mobile app -
-
Certify the Prevent Screen Sharing Scams & Malware > Block AirPlay feature in iOS Apps
After building Prevent Screen Sharing Scams & Malware > Block AirPlay, Appdome generates a Certified Secure™ certificate to guarantee that the Prevent Screen Sharing Scams & Malware > Block AirPlay protection has been added and is protecting the app. To verify that the Prevent Screen Sharing Scams & Malware > Block AirPlay protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
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 Prevent Screen Sharing Scams & Malware > Block AirPlay has been added to each iOS app. Certified Secure provides instant and in-line DevSecOps compliance certification that Prevent Screen Sharing Scams & Malware > Block AirPlay and other mobile app security features are in each build of the mobile app.
Using Threat-Events™ for AirPlay Intelligence and Control in iOS Apps
Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when AirPlay is detected. To consume and use Threat-Events™ for AirPlay in iOS Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for AirPlay shown below.
The specifications and options for Threat-Events™ for AirPlay are:
Threat-Event™ Elements | Block AirPlay Method Detail |
