How to Detect SU Binaries in iOS Apps
Learn to Detect SU Binaries in iOS apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.
What are SU Binaries on iOS?
SU Binaries, also known as “SuperUser” or simply “SU,” play a crucial role in iOS jailbreaking. When an iOS device is “jailbroken,” the user gains elevated (superuser) privileges, enabling them to modify or access system components that would typically be restricted. These elevated permissions are facilitated by the SU binary.
Why Detect SU Binaries in iOS Apps?
If an iOS device has undergone jailbreaking, it can circumvent system security mechanisms, modify system settings, remove or alter system apps, and potentially install malicious software without the user’s awareness. This can put the user’s private data at risk and make the device susceptible to various threats, including memory dumping, debugging, data theft, and more. Detecting SU binaries helps ensure that apps operate as designed and that user data remains protected.
Prerequisites for Using Detect SU Binaries:
To use Appdome’s mobile app security build system to Detect SU Binaries , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Detect SU Binaries
- Mobile App (.ipa for iOS)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
Detect SU Binaries on iOS apps using Appdome
On Appdome, follow these simple steps to create self-defending iOS Apps that Detect SU Binaries without an SDK or gateway:
Upload the Mobile App to Appdome.
Upload an app to Appdome’s Mobile App Security Build System
Upload Method: Appdome Console or DEV-API
iOS Formats: .ipa
Detect SU Binaries Compatible With: Obj-C, C+, Java, Swift, Flutter, React Native, Unity, Xamarin, Cordova and more
Build the feature: Detect SU Binaries.
Congratulations! The Detect SU Binaries protection is now added to the mobile app
Building Detect SU Binaries by using Appdome’s DEV-API:
Create and name the Fusion Set (security template) that will contain the Detect SU Binaries feature as shown below:
Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Detect SU Binaries feature via Appdome Console, to add the Detect SU Binaries feature to this Fusion Set.
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):
Figure 2: Fusion Set Detail Summary
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).
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:

Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).
Building the Detect SU Binaries feature via Appdome Console
To build the Detect SU Binaries protection by using Appdome Console, follow the instructions below.
Where: Inside the Appdome Console, go to Build > Security Tab > OS Integrity section.
When you enable Jailbreak Detection 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 SU Binaries

Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
Certify the Detect SU Binaries feature in iOS Apps.
After building Detect SU Binaries, Appdome generates a Certified Secure™ certificate to guarantee that the Detect SU Binaries protection has been added and is protecting the app. To verify that the Detect SU Binaries 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 SU Binaries has been added to each iOS app. Certified Secure provides instant and in-line DevSecOps compliance certification that Detect SU Binaries and other mobile app security features are in each build of the mobile app
Using Appdome, there are no development or coding prerequisites to build secured iOS Apps by using Detect SU Binaries. 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 SU Binaries
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:
- Customizing, Configuring & Branding Secure Mobile Apps
