How to Detect Frida and Frida Methods in Android & iOS Apps

Last updated November 27, 2023 by Appdome

Learn to Detect Frida and Frida Methods in Mobile apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is Frida?

Frida is a dynamic/binary instrumentation toolkit intended for developers, pen-testers, and security researchers. Frida has official builds made by the Frida.re website, while a custom Frida toolkit is a non-official Frida typically used by malicious actors to compromise mobile apps, inject malicious code, or change a mobile app’s logic or behavior in unintended and malicious ways, such as creating an update to existing malware, disabling SSL/TLS Pinning, and intercepting the network traffic via a middleman proxy. In addition, Custom Frida can be used to reverse engineer how apps work and obtain knowledge on an undocumented API used in an app.

Why Detect Frida and Its Methods in Mobile Apps?

By opting to detect Frida and Frida methods, developers can thwart cybercriminals who might employ custom Frida toolkits to exploit mobile apps, inject malicious code, or modify an app’s logic in hazardous ways. Detecting Frida methods is also crucial since a custom Frida toolkit can be used to reverse-engineer application functionalities and extract insights from undocumented APIs used by Android apps. By implementing detection mechanisms for Frida and its methods, mobile applications are protected from potential threats.

Prerequisites for Using Detect Frida and Frida Methods:

To use Appdome’s mobile app security build system to Detect Frida and Frida Methods , you’ll need:

Detect Frida and Frida Methods on Mobile apps using Appdome

On Appdome, follow these simple steps to create self-defending Mobile Apps that Detect Frida and Frida Methods without an SDK or gateway:

  1. Upload the Mobile App to Appdome.

    1. Upload an app to Appdome’s Mobile App Security Build System

    2. Upload Method: Appdome Console or DEV-API
    3. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
    4. Detect Frida and Frida Methods Compatible With: Obj-C, C+, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more
  2. Build the feature: Detect Frida and Frida Methods.

    1. Building Detect Frida and Frida Methods by using Appdome’s DEV-API:

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

        Figure 1: Fusion Set that will contain the Detect Frida and Frida Methods feature
        Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).

      3. Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Detect Frida and Frida Methods feature via Appdome Console, to add the Detect Frida and Frida Methods feature to this Fusion Set.

      4. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set, as shown in Figure 1 above, and get the Fusion Set ID from the Fusion Set Detail Summary (as shown below): fusion Set Detail Summary image

        Figure 2: Fusion Set Detail Summary
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Cirlce CI or other system:
        1. Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
        2. Look for sample APIs in Appdome’s GitHub Repository
    2. Building the Detect Frida and Frida Methods feature via Appdome Console

      To build the Detect Frida and Frida Methods protection by using Appdome Console, follow the instructions below.

      1. Where: Inside the Appdome Console, go to Build > Anti Fraud Tab > Mobile Malware Prevention section.
      2. When you enable Block Frida you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Detect Frida and Frida Methods

        Fusion Set applied Detect Frida and Frida Methods

        Figure 4: Fusion Set that displays the newly added Detect Frida and Frida Methods protection

      3. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
    Congratulations!  The Detect Frida and Frida Methods protection is now added to the mobile app

Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using Detect Frida and Frida Methods. 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.

Releasing and Publishing Mobile Apps with Detect Frida and Frida Methods

After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
