Threat-Events™, In-App Threat Intelligence in Native Android Apps

Last updated August 20, 2024 by Appdome

This knowledge base article shows you how easy it is to use Appdome Threat-Events™ to get in-app threat intelligence in native Android apps and control the user experience in your native Android apps when mobile attacks occur.

What are Threat-Events?

Appdome Threat-Events is a powerful threat-intelligence framework for Android & iOS apps, which is comprised of three elements: (1) a Threat-Event, (2) the data from each Threat-Event, and (3) the Threat-Score™.

With Threat-Events, mobile developers can register, listen to, and consume real-time attack and threat data from Appdome’s mobile app security, anti-fraud, mobile anti-bot, and other protections within their mobile applications. This allows them to (1) ensure that mobile application workflows are aware of attacks and threats, (2) customize business logic and user experience based on the user’s risk profile and/or each attack or threat presented, and (3) pass the threat data to other systems of record such as app servers, mobile fraud analysis systems, SIEMs, and other data collection points.

The purpose of Threat-Events is to enable Android and iOS applications to adapt and respond to mobile app attacks and threats in real-time. Using Threat-Events will ensure you keep users, data, and transactions safe.

Mobile Application Threat-Events vs. Threat-Scores

Appdome Threat-Events can be used as a stand-alone implementation in Native Android Apps, or in combination with Threat-Scores. Threat-Events provide the mobile developer with the in-app notification of each attack or threat, as well as the metadata associated with the attack. Threat-Scores provide the mobile developer with the Threat-Event event score and the combined (aggregate) mobile end-user risk at the time of the notification.

Threat Events™, In App Threat Intelligence In Native Ios Apps

The figure below shows where you can find Threat-Events and Threat-Scores for each of the runtime mobile app security, anti-fraud, anti-malware, mobile antibot, and other protections available on Appdome:

To enable Threat-Events with any runtime protection, select the check box next to Threat-Events for that feature. Doing so will enable (turn ON) Threat-Events for that feature. To enable Threat-Scores for any runtime protection, click the up/down arrow associated with Threat-Scores to assign a specific score to each protection.
Threat-Scores must have a value greater than zero (0) and less than a thousand (1,000).

Threat-Events and Threat-Scores can be used with or in place of server-based mobile anti-fraud solutions.

Prerequisites for Using Threat-Events with Native Android Apps

Here’s what you need to use Threat-Events with native Android apps:

Appdome account (If you do not yet have an account, create a free Appdome account).
Appdome account class – Appdome DEV or higher.
Mobile Application Source Code.
Signing Credentials (e.g., signing certificates and provisioning profile) – see Signing Secure Android apps.

Code Snippet Required for Using Threat-Events with Native Android Apps

Before consuming Threat-Events or Threat-Scores in your Native Apps, confirm that the following conditions are met:

Threat-Events and/or Threat-Scores have been enabled ( turned ON) for the specific protection
You are using the correct identifiers for the Threat-Events for each protection.
You can find the specific identifiers for each Threat-Event and Threat-Score in the knowledge base article associated with each protection.

Threat-Event Failsafe Enforcement

Failsafe Enforcement provides app developers with the ability to manage when Appdome enforces specific detections. To utilize this feature, follow the steps below:

Set the Threat Event of the selected feature to “In-App Detection” mode.
Enable the Threat-Event Failsafe Enforcement option.

Once you have received the Threat Event and performed the necessary internal logic, you should post a notification named “EnforceThreatEvent” using Android’s Broadcast API with the userInfo received from the Threat Event. Below is the code snippet required for using Threat Event in Failsafe Enforcement configuration, with the RootedDevice event as an example:

String action = intent.getAction();
switch (action) {
    case ROOTED_DEVICE:
    //
    // Respond to mobile app attacks and threats here, as seen above
    //

    // Notify Appdome to enforce the Threat Event after Threat Event is handled
    Intent newIntent = new Intent("EnforceThreatEvent");
    newIntent.putExtras(intent.getExtras());
    newIntent.setPackage(context.getPackageName());
    context.sendBroadcast(newIntent);
}

Special Considerations for Using Threat-Events with Native Android Apps

None.

Compatibility with Android 14

Following a security update introduced in Android 14 (API level 34), apps targeting Android 14 are required to explicitly specify whether a registered receiver should be exported to all other apps on the device. A SecurityException will be raised if a context-registered broadcast receiver is registered without passing either Context.RECEIVER_NOT_EXPORTED or Context.RECEIVER_EXPORTED. The receiver flags were introduced in Android 13 as part of "Safer exporting of context-registered receivers", as seen here: [https://developer.android.com/about/versions/13/features#runtime-receivers]. Therefore when registering a broadcast receiver for Threat Events, the call to register a a context-registered BroadcastReceiver registration should include the Context.RECEIVER_NOT_EXPORTED receiver flag when the app targeting Android 13 and above in order to ensure that the receiver will only accept broadcasts sent from within the protected app. For additional details, please follow this Android guide: [https://developer.android.com/guide/components/broadcasts#context-registered-receivers]

Meta-Data for Mobile Application Threat-Events and Threat-Scores

Below is the list of metadata that can be associated with each mobile application Threat-Event and Threat-Score in native Android apps.

Threat-Event Context Keys
message	Message displayed for the user on event
failSafeEnforce	Timed enforcement against the identified threat
externalID	The external ID of the event which can be listened via Threat Events
osVersion	OS version of the current device
deviceModel	Current device model
deviceManufacturer	The manufacturer of the current device
fusedAppToken	The task ID of the Appdome fusion of the currently running app
kernelInfo	Info about the kernel: system name, node name, release, version and machine.
carrierPlmn	PLMN of the device. Only available for Android devices.
deviceID	Current device ID
reasonCode	Reason code of the occurred event
buildDate	Appdome fusion date of the current application
devicePlatform	OS name of the current device
carrierName	Carrier name of the current device. Only available for Android.
updatedOSVersion	Is the OS version up to date
deviceBrand	Brand of the device
deviceBoard	Board of the device
buildUser	Build user
buildHost	Build host
sdkVersion	Sdk version
timeZone	Time zone
deviceFaceDown	Is the device face down
locationLong	Location longitude conditioned by location permission
locationLat	Location latitude conditioned by location permission
locationState	Location state conditioned by location permission
wifiSsid	Wifi SSID
wifiSsidPermissionStatus	Wifi SSID permission status

Some or all of the meta-data for each mobile application Threat-Event and Threat-Score can be consumed in Native Android Apps at the discretion of the mobile developer and used, in combination with other mobile application data, to adapt the business logic or user experience when one or more attacks or threats are present.

Using Conditional Enforcement for Mobile Application Threat-Events and Threat-Scores

Conditional Enforcement is an extension to Appdome's mobile application Threat-Event framework. By using conditional enforcement, developers can control when Appdome enforcement of each mobile application protection takes place or invoke backup, failsafe, and enforcement to any in-app enforcement used by the mobile developer.
For more information on using conditional enforcement with your Threat-Event implementation, please contact support.appdome.com.

Verifying Threat-Events in Native Android Apps

After you have implemented the required Threat-Event code in your native Android apps, you can confirm that your Threat-Event implementation(s) is properly recognized by the Appdome protections in the native Android apps. To do that, review the Certified Secure™ DevSecOps certificate for your build on Appdome.

In the Certified Secure DevSecOps certificate, a correct implementation of Threat-Events in your mobile application looks as seen below.

Root Detection Cert

In the Certified Secure DevSecOps certificate, an incorrect implementation of Threat-Events in your mobile application looks as seen below.
