Dynamic Application Security Testing (DAST) is an essential component of mobile application security assessments. During a DAST engagement, the application is executed in a real environment while its behavior, network communications, authentication mechanisms, and client-side controls are analyzed.

Many security professionals assume that iOS application testing requires a macOS environment. While macOS is often necessary for advanced activities such as jailbreak development, runtime instrumentation, reverse engineering, and iOS application compilation, a Windows-based environment can be sufficient for basic dynamic testing tasks.

By combining an iPhone, a Windows workstation, Sideloadly, and Burp Suite, security testers can install IPA files, intercept application traffic, and perform a variety of common security assessment activities without requiring access to macOS.

This guide demonstrates how to prepare an iPhone for dynamic application security testing using a Windows machine.

Prerequisites

Before you begin, ensure you have the following:

  • An iPhone
  • A Windows PC or laptop
  • A USB cable
  • An Apple ID
  • The target iOS application (.ipa file)

Step 1: Install iTunes for Windows

iTunes installs the Apple Mobile Device drivers required for Windows to recognize and communicate with iOS devices. Without these drivers, tools such as Sideloadly may fail to detect connected devices.

Download and install Apple iTunes for Windows .

After installation:

  1. Connect your iPhone using a USB cable.
  2. Launch iTunes.
  3. Verify that the device is detected successfully.

Successful detection confirms that the required Apple drivers are installed correctly.

None

Step 2: Install iCloud for Windows

Before using Sideloadly to install applications on your iPhone or iPad, you must install iCloud for Windows and sign in with your Apple ID. This process installs the necessary Apple components and services that Sideloadly relies on to authenticate your Apple ID, sign applications, and communicate properly with your iOS device.

Steps to Install and Configure iCloud

  1. Download and install Apple iCloud for Windows.
  2. Launch iCloud.
  3. Sign in using the Apple ID that will be used for application signing.
  4. Complete any multi-factor authentication requirements associated with the account.
None

Step 3: Install Sideloadly

After configuring the required Apple services on your computer, the next step is to install Sideloadly. Sideloadly is a desktop application that allows you to sideload IPA files onto your iPhone or iPad by signing them with your Apple ID and transferring them directly to the device.

Visit the official Sideloadly website and download the latest version for Windows.

  1. Run the downloaded installer and follow the on-screen instructions to complete the installation.
  2. Once the installation finishes, launch Sideloadly from the Start menu or desktop shortcut.

Step 4: Connect and Trust the Device

  • Use a reliable USB cable to connect your iPhone to your Windows computer.
  • If this is the first time connecting the device, your iPhone may display a "Trust This Computer?" prompt.
  • Tap Trust on the device and enter your passcode when requested.
  • Wait a few moments for Windows and Apple device services to recognize the connected device.

Step 5: Sideload the Application

With the device connected and recognized by Sideloadly, the target application can now be installed on the iPhone.

  1. Open Sideloadly.
  2. Select the target IPA file.
  3. Enter the Apple ID that will be used for application signing.
  4. Click Start to begin the sideloading process.

Sideloadly will authenticate with Apple's services, sign the IPA using the supplied Apple ID, and transfer it to the connected device. The installation process may take several minutes to complete depending on the size of the application and the speed of the connection.

Once the process finishes successfully, the application should appear on the iPhone's Home Screen or App Library, indicating that it has been installed successfully.

None

Step 6: Trust the Developer Profile

After installation, the application should appear on the iPhone Home Screen.

When launching the application for the first time, iOS may display an Untrusted Developer warning. This occurs because the application has been signed using a non-App Store certificate.

To trust the application, open Settings.

  1. Navigate to General → VPN & Device Management.
  2. Locate the developer profile associated with your Apple ID.
  3. Tap the profile and select Trust.
  4. Confirm the action when prompted.

After completing this step, return to the Home Screen and launch the application again to verify that it runs successfully.

Step 7: Configure Burp Suite (Traffic Interception Setup)

To perform effective Dynamic Application Security Testing (DAST), application traffic must be intercepted and analyzed. This is achieved by configuring Burp Suite as an HTTP/HTTPS proxy between the iPhone and the target application.

Start Burp Suite

  1. Launch Burp Suite on your Windows machine.
  2. Navigate to Proxy → Proxy settings (or Options, depending on version).
  3. Confirm that a proxy listener is active on port 8080.
  4. Ensure the listener is bound to either:
  • All interfaces
  • The Windows machine's local IP address

Open Command Prompt and run:

ipconfig

Locate the IPv4 address of the active network adapter. This will be used as the proxy server address on the iPhone.

Configure iPhone Proxy

Ensure both the iPhone and Windows machine are connected to the same Wi-Fi network.

On the iPhone:

  1. Open Settings → Wi-Fi.
  2. Tap the (i) icon next to the connected network.
  3. Scroll to Configure Proxy.
  4. Select Manual.
  5. Enter the following:
  • Server: Windows IPv4 address
  • Port: 8080
  1. Tap Save.

Install Burp Suite CA Certificate

To enable HTTPS traffic inspection:

  1. Open Safari on the iPhone.
  2. Navigate to:http://burp
  3. Download the CA certificate.
  4. Install the certificate profile when prompted.

Trust the Certificate

After installation:

  1. Open Settings → General → About → Certificate Trust Settings.
  2. Locate the Burp Suite certificate.
  3. Enable Full Trust for Root Certificates.

Verify Interception

Return to Burp Suite and ensure interception is enabled. Launch the target application and perform normal interactions. If configured correctly, HTTP and HTTPS requests will appear in :

  • Proxy → Intercept
  • HTTP history

Note: Some iOS applications implement SSL/TLS certificate pinning, which may prevent HTTPS traffic from being intercepted even when the Burp Suite certificate is trusted. Additional testing techniques may be required to analyze applications that use certificate pinning. Ensure traffic interception is performed only on applications and environments within the authorized testing scope.

Ready for Dynamic Testing

With the application successfully installed and traffic interception configured, the device is ready for Dynamic Application Security Testing.

Common testing activities include:

  • Network traffic analysis
  • Authentication and session management testing
  • Input validation testing
  • API security assessment
  • Business logic testing
  • Client-side security review

Important Notes

  • A paid Apple Developer account is not required for basic sideloading.
  • Applications installed using a standard Apple ID may need to be re-signed periodically.
  • Some advanced iOS security testing techniques may require additional tooling or a macOS-based environment.
  • Applications that implement certificate pinning may require additional bypass techniques before HTTPS traffic can be inspected.

Conclusion

Setting up an iOS testing environment on Windows is straightforward when using the right tools. By combining iTunes, iCloud for Windows, Sideloadly, and Burp Suite, security researchers and penetration testers can install, run, and assess iOS applications without requiring a macOS system.

This setup provides a practical starting point for mobile application security testing and iOS DAST assessments, enabling testers to perform traffic analysis, authentication testing, API assessment, and other common security evaluation activities from a Windows-based environment.
