How to Detect Gold Pickaxe Malware in iOS Mobile Apps
This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Detect Gold Pickaxe Malware in iOS apps.
What is Gold Pickaxe Malware?
Gold Pickaxe malware is a sophisticated iOS trojan discovered by the security firm Group-IB. It is notable for being one of the first of its kind to target iOS devices. Once installed on an iPhone, Gold Pickaxe can perform a range of malicious activities, including collecting a user’s biometric information from photos, intercepting SMS text messages, and monitoring web activity. This level of access allows the attacker to remotely control significant aspects of the device, such as taking screenshots, restricting device functionalities, and manipulating application behaviors. The malware achieves this by exploiting vulnerabilities in the device’s operating system and leveraging sophisticated command-and-control (CNC) techniques to maintain persistent and covert access to the compromised device.
How Does Appdome Detect Gold Pickaxe Malware?
Appdome’s approach to defending against Gold Pickaxe malware involves detecting whether critical stages of the malware have been installed on the device, specifically through Mobile Device Management (MDM). The MDM stage allows a device to execute remote management commands or queries, indicating a potential compromise.
Our Detect Gold Pickaxe plugin performs two primary detections:
Checking the existence of MDM profiles: Appdome determines if an unauthorized MDM profile is installed by checking specific indicators on the device.
Registering for MDM server message notifications: This method captures changes in the device’s MDM configuration, alerting to potential malware activity.
Additionally, the “Detect CNC Malware Commands” sub-toggle enhances protection by analyzing network traffic and system logs for suspicious CNC command patterns. CNC (Command-and-Control) commands are instructions sent by a remote attacker to control the infected device, such as retrieving data, executing specific tasks, or modifying settings. This comprehensive defense mechanism ensures that any attempts by Gold Pickaxe malware to control the device or execute malicious commands are promptly detected and addressed, safeguarding the user’s data and device integrity.
Prerequisites for Using Appdome's Detect Gold Pickaxe Malware Plugins:
To use Appdome’s mobile app security build system to Detect Gold Pickaxe Malware , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Detect Gold Pickaxe Malware
- Mobile App (.ipa for iOS)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
How to Implement Detect Gold Pickaxe Malware in iOS Apps Using Appdome
On Appdome, follow these 3 simple steps to create self-defending iOS Apps that Detect Gold Pickaxe Malware 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
-
Detect Gold Pickaxe Malware is compatible with: Obj-C, Java, Swift, Flutter, React Native, Unity, Xamarin, Cordova and other iOS apps.
-

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 Detect Gold Pickaxe Malware:
-
Threat-Events™ OFF > In-App Defense
If the Threat-Events™ setting is not selected. Appdome will detect and defend the user and app by enforcing Gold Pickaxe Malware.
-
Threat-Events™ ON > In-App Detection
When this setting is used, Appdome detects Gold Pickaxe malware has been installed on the iOS mobile device 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™ to Detect Gold Pickaxe MalwareDetect Intelligence and Control in Mobile Apps.
-
Threat-Events™ ON > In-App Defense
When this setting is used, Appdome detects and defends against Gold Pickaxe Malware (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 Detect Gold Pickaxe MalwareDetect Intelligence and Control in Mobile Apps.
