How to Prevent Logging Attacks in iOS Apps Using AI

Last updated February 9, 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 Prevent Logging Attacks in iOS apps.

What are iOS Logging Attacks?

While logging is essential for troubleshooting, logging can create security vulnerabilities if sensitive information such as passwords, API keys, or PII is inadvertently logged. Logs can be accessed via Xcode’s Console or developer tools, enabling attackers to extract sensitive data, reverse engineer the app, or exploit vulnerabilities. Excessive logging also provides attackers with insights into the app’s internal behavior, making it easier to identify weaknesses and develop exploits. Preventing logging attacks is critical for safeguarding user data, maintaining app security, and complying with privacy regulations. However, achieving this is challenging as developers rely on logging for production troubleshooting, requiring careful management to avoid recording sensitive data while retaining debugging capabilities.

How Appdome Protects Against Logging Attacks?

Appdome’s dynamic Prevent Logging Attack plugin for iOS identifies and blocks attempts to log sensitive app data by monitoring logging activities in real-time. The plugin prevents the exposure of confidential information by sanitizing logs and ensuring sensitive data like credentials or API keys are not recorded. This protection mitigates risks of reverse engineering and unauthorized data access.

Prerequisites for Using Appdome's Prevent Logging Attacks Plugins:

To use Appdome’s mobile app security build system to Prevent Logging Attacks , you’ll need:

How to Implement Prevent Logging Attacks in iOS Apps Using Appdome

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

      1. Create and name the Fusion Set (security template) that will contain the Prevent Logging Attacks feature as shown below:
        fusion set that contains Prevent Logging Attacks

        Figure 1: Fusion Set that will contain the Prevent Logging Attacks feature

      2. Follow the steps in Sections 2.2-2.2.2 of this article to add the Prevent Logging Attacks feature to your Fusion Set via the Appdome Console.

      3. When you select the Prevent Logging Attacks you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Prevent Logging Attacks.

        Fusion Set applied Prevent Logging Attacks

        Figure 2: Fusion Set that displays the newly added Prevent Logging Attacks 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 Prevent Logging Attacks feature to your security template.

      1. Navigate to Build > Anti ATO tab > iOS Trojans section in the Appdome Console.
      2. Toggle On > Prevent Logging Attacks.
        Prevent Logging Attacks option

        Figure 4: Selecting Prevent Logging Attacks

    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 Prevent Logging Attacks protection is now added to the mobile app
  3. Certify the Prevent Logging Attacks feature in iOS Apps

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

Using Threat-Events™ for Logging Attacks Intelligence and Control in iOS Apps

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

The specifications and options for Threat-Events™ for Logging Attacks are:

Threat-Event™ Elements Prevent Logging Attacks Method Detail
Appdome Feature Name Prevent Logging Attacks
Threat-Event Mode
OFF, IN-APP DEFENSE Appdome detects, defends and notifies user (standard OS dialog) using customizable messaging.
ON, IN-APP DETECTION Appdome detects the attack or threat and passes the event in a standard format to the app for processing (app chooses how and when to enforce).
ON, IN-APP DEFENSE Uses Appdome Enforce mode for any attack or threat and passes the event in a standard format to the app for processing (gather intel on attacks and threats without losing any protection).

With Threat-Events™ enabled (turned ON), iOS developers can get detailed attack intelligence and granular defense control in iOS applications and create amazing user experiences for all mobile end users when Logging Attacks is detected.


The following is a code sample for native iOS apps, which uses all values in the specification above for Prevent Logging Attacks:


Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.



Using Appdome, there are no development or coding prerequisites to build secured Apps by using Prevent Logging Attacks. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
