How to Prevent Stream Manipulation in Android Apps

Last updated August 18, 2024 by Appdome

This Knowledge Base article describes how to use Appdome’s AI/ML in your CI/CD pipeline to continuously deliver plugins that Prevent Stream Manipulation in Android apps.

What is Stream Manipulation?

Stream manipulation, also known as the “Dirty Stream” attack, is a significant security threat that targets mobile applications by exploiting path traversal vulnerabilities.

What is a URI?

A URI, or Uniform Resource Identifier, is a fundamental concept in mobile app development. It serves as a unique identifier for a resource within an app, much like a URL (Uniform Resource Locator) identifies a web page. URIs can represent various types of resources, including files, database entries, or content shared between apps. For instance, in Android apps, URIs often start with “file://” to access files on the device or “content://” to access data shared by other apps.

How Stream Manipulation Attacks Work

In a stream manipulation attack, malicious actors tamper with URIs to trick the app into accessing or modifying files it shouldn’t. For example, an attacker might craft a URI that navigates outside of the app’s designated area, potentially accessing sensitive information or executing unauthorized operations. This can lead to severe consequences, including data breaches, unauthorized data modification, or even a complete system compromise.

How Appdome Secures Android Apps Against Stream Manipulation

Appdome’s Prevent Stream Manipulation feature offers robust protection against these attacks by addressing the vulnerabilities that allow them. Here’s a detailed look at how Appdome secures your Android apps:

1. Advanced Threat Detection

Appdome continuously monitors all URIs processed by the app to identify unusual patterns or structures that could indicate a manipulation attempt.

2. URI Sanitization Process

When Appdome detects a potentially dangerous URI, it sanitizes it. This ensures the URI is safe to use, allowing the app to function normally without risking exposure to sensitive data.

3. Proactive Application Protection

If Appdome identifies a URI that poses a significant threat, it proactively closes the application to prevent any unauthorized access or data leakage. In addition to closing the app, Appdome provides an immediate notification to the user, explaining that the app was shut down for security reasons. This transparency helps maintain user trust by clearly communicating the protective actions taken on their behalf.

Prerequisites for Using Appdome's Prevent Stream Manipulation Plugins:

To use Appdome’s mobile app security build system to Prevent Stream Manipulation , you’ll need:

Appdome account (create a free Appdome account here)
A license for Prevent Stream Manipulation
Mobile App (.apk or .aab for Android)
Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
A license for Threat Events

How to Implement Prevent Stream Manipulation in Android Apps Using Appdome

On Appdome, follow these 3 simple steps to create self-defending Android Apps that Prevent Stream Manipulation without an SDK or gateway:

Designate the Mobile App to be protected.
1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
2. Android Formats: .apk or .aab
3. Prevent Stream Manipulation is compatible with: Java, JS, C++, C#, Kotlin, Flutter, React Native, Unity, Xamarin, Cordova and other Android apps.
Select the defense: Prevent Stream Manipulation.

Create and name the Fusion Set (security template) that will contain the Prevent Stream Manipulation feature as shown below:

Figure 1: Fusion Set that will contain the Prevent Stream Manipulation feature

Follow the steps in Sections 2.2-2.2.2 of this article to add the Prevent Stream Manipulation feature to your Fusion Set via the Appdome Console.

When you select the Prevent Stream Manipulation you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Prevent Stream Manipulation.

Figure 2: Fusion Set that displays the newly added Prevent Stream Manipulation protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below):

Figure 3: Fusion Set Detail Summary

Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:

Refer to the Appdome API Reference Guide for API building instructions.

Look for sample APIs in Appdome’s GitHub Repository.

Add the Prevent Stream Manipulation feature to your security template.

Navigate to Build > Anti Fraud tab > Mobile Malware Prevention section in the Appdome Console.
Like all other options in ONEShield™, Prevent Stream Manipulation is turned on by default, as shown below:
Figure 4: Selecting Prevent Stream Manipulation
Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

Toggle On > Prevent Stream Manipulation.

(a) Choose to monitor this attack vector by checking the Threat Events checkbox associated with Prevent Stream Manipulation as shown below.

(b) To receive mobile Threat Monitoring, check the ThreatScope™ box as shown below. For more details, see our knowledge base article on ThreatScope™ Mobile XDR.

Figure 4: Selecting Prevent Stream Manipulation
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 Prevent Stream Manipulation:

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 Stream Manipulation.

Threat-Events™ ON > In-App Detection
When this setting is used, Appdome detects stream manipulation 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 Prevent Stream ManipulationPrevent Intelligence and Control in Mobile Apps.

Threat-Events™ ON > In-App Defense
When this setting is used, Appdome detects and defends against Stream Manipulation (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 Prevent Stream ManipulationPrevent Intelligence and Control in Mobile Apps.

Configure the User Experience Options for Prevent Stream Manipulation:
With Threat-Events™ OFF, Appdome provides several user experience options for mobile brands and developers.

App Compromise Notification: Customize the pop-up or toast Appdome uses to notify the user when a threat is present while using the protected mobile app.

Short message Option. This is available for mobile devices that allow a banner notification for security events.

Localized Message Option. Allows Appdome users to support global languages in security notifications.

Figure 5: Default User Experience Options for Appdome’s Stream Manipulation

Prevent Stream Manipulation Threat Code™. Appdome uses AI/ML to generate a unique code each time Prevent Stream Manipulation is triggered by an active threat on the mobile device. Use the code in Appdome Threat Resolution Center™ to help end users identify, find and resolve active threats on the personal mobile devices.

Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.

Congratulations! The Prevent Stream Manipulation protection is now added to the mobile app

Certify the Prevent Stream Manipulation feature in Android Apps

After building Prevent Stream Manipulation, Appdome generates a Certified Secure™ certificate to guarantee that the Prevent Stream Manipulation protection has been added and is protecting the app. To verify that the Prevent Stream Manipulation protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:

Figure 6: 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 Prevent Stream Manipulation has been added to each Android app. Certified Secure provides instant and in-line DevSecOps compliance certification that Prevent Stream Manipulation and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Stream Manipulation Intelligence and Control in Android Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Stream Manipulation is detected. To consume and use Threat-Events™ for Stream Manipulation in Android Apps, use registerReceiver in the Application OnCreate, and the code samples for Threat-Events™ for Stream Manipulation shown below.
