Common Vulnerabilities in Android Apps: What Developers Need to Know

As the world’s most popular mobile operating system, Android has become an attractive target for cybercriminals. With billions of devices in use, securing Android apps is a critical responsibility for developers. Failure to do so can lead to serious breaches, compromising both user data and the reputation of businesses. Here, we’ll walk through some of the most common vulnerabilities found in Android apps and provide best practices for developers to mitigate these risks.

1. Insecure Local Data Storage

A common oversight in Android app development is storing sensitive data, such as passwords or personal information, on the device without using secure storage methods. When sensitive data is stored in plaintext, it becomes vulnerable if the device is lost, stolen, or compromised by malicious software.

Recommendation:

Always encrypt sensitive data stored locally on the device. Use Android’s KeyStore to securely store encryption keys, ensuring that even if attackers access the device, they cannot easily read the data.

2. Lack of Input Validation

Failure to properly validate user inputs can lead to severe vulnerabilities like SQL injection or command injection. Attackers often exploit these flaws by sending malicious data, potentially allowing them to bypass authentication or access restricted areas of the app.

Recommendation:

Strictly validate and sanitize all user inputs. Use input validation frameworks available within Android to ensure that the data being processed meets security standards. This simple step can prevent a range of attacks.

3. Unprotected Data Transmission

Many Android apps handle sensitive data, including user credentials and financial information, that is sent over the internet. If this data is not encrypted during transmission, it can easily be intercepted by attackers through man-in-the-middle attacks.

Recommendation:

Ensure all data sent over the network is encrypted using HTTPS (SSL/TLS). In addition, apply certificate pinning to safeguard against fake certificates and prevent attackers from intercepting encrypted communications.

4. Weak Authentication Mechanisms

Inadequate authentication mechanisms, such as weak password policies or poorly managed session tokens, open up opportunities for attackers to gain unauthorized access. Attackers can exploit these flaws to steal user credentials or take control of user accounts.

Recommendation:

Enforce strong password policies and encourage multi-factor authentication (MFA) to enhance security. Manage session tokens securely by using HTTPS for all communication and employing secure cookie flags, such as HttpOnly and Secure, to prevent session hijacking.

5. Exposure to Reverse Engineering

Android apps are often decompiled by attackers, which allows them to study the app’s source code and find weaknesses. Sensitive data or logic implemented directly in the app code can be exposed, making the app easier to compromise.

Recommendation:

Use code obfuscation tools such as ProGuard or R8 to make it difficult for attackers to understand your code. Avoid storing sensitive information, like encryption keys or proprietary logic, in the app itself—such data should be stored on secure servers instead.

6. Excessive Permission Requests

Android apps request permissions from users to access device resources, such as the camera or location services. However, apps requesting unnecessary permissions can expose sensitive data or provide opportunities for misuse if these permissions are exploited by attackers.

Recommendation:

Adopt a “least privilege” approach, requesting only the permissions that are absolutely necessary for the app to function. Review permissions regularly to ensure the app isn’t asking for unnecessary access, which can reduce the risk of unauthorized access to sensitive information.

7. Using Outdated Libraries

Third-party libraries and SDKs are often included in Android apps for functionality. However, outdated libraries can contain known vulnerabilities, making the app vulnerable to attack.

Recommendation:

Keep all third-party libraries and SDKs updated to the latest versions. Regularly monitor dependencies for known security issues and patch them as soon as updates are available. This proactive approach will help protect the app from known exploits.

8. Hardcoding Sensitive Information

Hardcoding sensitive data, such as API keys or credentials, directly into the app’s code is a dangerous practice. If an attacker decompiles the app, this information can be easily retrieved and used to exploit the app or backend systems.

Recommendation:

Never hardcode sensitive information into the app’s source code. Instead, use environment variables or secure vaults to store such data. Cloud-based tools like Google Cloud Secret Manager or AWS Secrets Manager can be leveraged for this purpose.

9. Insecure WebView Usage

Many Android apps use WebView to load web content. If improperly configured, WebView can expose the app to security risks, including JavaScript-based attacks or exploitation via malicious web pages.

Recommendation:

Disable JavaScript in WebView unless absolutely necessary. If JavaScript is needed, ensure it is sandboxed and used only with trusted sources. Additionally, prevent WebView from loading content from untrusted or external URLs to mitigate risks.

Conclusion

Developers must remain vigilant in addressing vulnerabilities that can leave Android apps exposed to cyberattacks. By following secure coding practices and regularly updating security features, developers can greatly reduce risks. Protecting users and maintaining the integrity of the app requires a proactive approach to security at every stage of development.

Android app security isn’t just about the technical side; it’s also about maintaining the trust of your users and safeguarding your company’s reputation. Developers should prioritize these best practices to create secure, reliable applications in a constantly evolving threat landscape.

Mobile device management, or MDM, is useful in this situation.

What is Mobile Device Management (MDM)?

A full suite of tools and procedures for managing, safeguarding, and keeping an eye on mobile devices within an enterprise is referred to as mobile device management or MDM. Administrators can manage several aspects of such devices, such as device settings, safety policies, utility management, tool performance, and compliance tracking, using a centralized platform provided by MDM solutions. VMware Workspace ONE, Microsoft Intune, MobileIron, and Cisco Meraki are a few examples of MDM solutions. In order for MDM to function, a control agent must be installed on the mobile device that has to be managed.

Why Mobile Device Management (MDM)?

MDM is essential for improving defensively sensitive data and mobile device security. It enables organizations to implement security procedures, control devices from a distance, prevent data breaches, and lessen the possibility of unwanted access. By simplifying device control, MDM ensures that workers have access to essential resources, which boosts productivity. MDM also makes it easier to manipulate fees, use music, and lose capabilities. MDM lowers downtime and helps a mobile workforce with remote instruction and troubleshooting capabilities. It’s important for protecting information, making sure rules are followed, and maximizing cell device performance in today’s mobile-centric society.

Essential Benefits of Mobile Device Management (MDM)

MDM solutions provide a number of critical benefits to help organizations efficiently control and secure cellular devices. Some key advantages encompass:

Enhanced Security: Protects against data breaches and unauthorized access by enforcing security regulations that include the need for passwords, encryption, and whitelisting or blacklisting.

Device Configuration: Gives administrators the ability to control and manage tool settings from a single location.

App management: Makes sure that only approved and secure apps are permitted on devices by managing app updates, installations, and permissions.

Data protection: Encrypts and backs up important documents.

Scalability: The capacity to adjust to the requirements of businesses with different sizes and fleets of devices.

Compliance Monitoring: Verifies that devices follow company regulations and organizational rules.

IT administrators: Offer remote assistance, debug issues, and carry out updates with the help of remote support, which lowers downtime and boosts productivity.

Cost control: Measures include tracking statistics utilization, cutting down on device-related costs, and putting an end to unauthorized pricing.

By enforcing MDM, agencies can make sure their cell devices are secure, compliant, and successfully managed, ultimately enhancing productivity and protecting touchy information.

Introduction to Android Penetration Testing

The write-up will be covering the basics about android and how to set up an android pentesting lab also will be coming across the two vulnerabilities that are common in all android applications.

Android

Android is an open-source mobile operating system. As it is open-source, android is the first choice for developers as well as consumers.

Android Architecture

The Android Operating System is divided into 4 layers.

Application Layer

As shown above, the first layer is the application layer, In which all the applications are being installed on the mobile phone. It runs within the Android run time with the help of the classes and services provided by the application framework.

Application Framework

The Application Framework layer provides many higher-level services to applications in the form of Java classes. Application developers are allowed to make use of these services in their applications. Content providers and activity managers are examples.

Content Provider : The content Provider component supplies data from one application to others on request. You can store the data in the file system, an SQLite database, on the web, or any other persistent storage location your app can access. Through the content provider, other apps can query or even modify the data (if the content provider allows it). Content Provider is useful in cases when an app wants to share data with another app.
Resource Manager : Provides access to non-code embedded resources such as strings, colour settings and user interface layouts.
Notifications Manager : Allows applications to display alerts and notifications to the user.
View System : An extensible set of views used to create application user interfaces.
Package Manager : The system by which applications can find out information about other applications currently installed on the device.
Telephony Manager : Provides information to the application about the telephony services available on the device such as status and subscriber information.
Location Manager : Provides access to the location services allowing an application to receive updates about location changes

Dalvik Virtual Machine | Android Run Time

Dalvik Virtual Machine : is specifically designed by the Android Open Source Project to execute applications written for Android. Each app running on the Android device has its own Dalvik Virtual Machine
Android Runtime (ART) : is an alternative to Dalvik Virtual Machine which has been released with Android 4.4 as an experimental release, in Android Lollipop (5.0) it will completely replace Dalvik Virtual Machine. A major change in ART is because of Ahead-of-Time (AOT) Compilation and Garbage Collection. In Ahead-of-Time (AOT) Compilation, Android apps will be compiled when the user installs them on their device, whereas Dalvik used Just-in-time(JIT) compilation in which bytecode is compiled when the user runs the app. Moving to the last one, these are common.

Libraries

These are external libraries which are used for additional features or additional functions.

Surface Manager : This manages the windows and screens.
Media Framework : This allows the use of various types of codecs for playback and recording of different media.
SQLite : This is a lighter version of SQL used for database management.
WebKit : This is the browser rendering engine.
OpenGL : This is used to render 2D and 3D contents on the screen properly.

Linux Kernel

This layer is responsible for allocating hardware for the applications. And this layer contain all the drivers.It provides Android with several key security features, like

Security Architecture

Android security architecture consists of two models. They are:

Linux Security Model

The Linux security model is were each app runs through a unique Linux user ID. Linux helps in isolating applications from each other.

Here you can witness that it’s inside the package folder of the application diva that is installed on the virtual device. The system has formed a user id (u0_a74) for every resource that is inside the package. So if there is any malicious application in the device they can’t affect or access other applications.

Android Security Model

In the android security model, the user’s privacy is protected by means of permissions. We all are familiar with the image shown above, we allow some of the permission that the application asking for. The permission is required by the application id declared in the AndroidManifest.xml file.

So, what is AndroidManifest.xml?

What is an APK?

AndroidManifest.xml

The AndroidManifest.xml file is the control file that tells the system what to do with all the top-level components (specifically activities, services, broadcast receivers, and content providers described below) in an application. This also specifies which permissions are required. This file may be in Android binary XML that can be converted into human-readable plaintext XML with tools such as android apktool.

META-INF directory

classes.dex

The classes are compiled in the dex file format understandable by the Dalvik virtual machine.

lib

The directory containing the compiled code that is specific to a software layer of a processor, the directory is split into more directories within it:

res

The directory containing resources not compiled into resources.arsc.

assets

A directory containing application’s assets, which can be retrieved by AssetManager.

resources.arsc

A file containing precompiled resources, such as binary XML, for example.

Setting up a lab

Prerequisites:

First we have to download Genymotion. So goto this link .

If you have already installed virtualbox on your pc then download Genymotion from the second option or if you have not installed virtualbox then download genymotion with virtualbox.

After completing the installation you have to download any virtual device. We choose to download Google Nexus 6. After that click the install button.

It’s time to customize your device. You can set the Network mode and other settings as you wish or you can follow the same settings shown in the above image. After completing, click install and wait until the installation to be completed.

We have almost gone across the processes for the completed setting up of the virtual device. The next step is to install Google Play Store on your virtual device, to do that click on the “OpenGapps” icon and the download will be started. After the installation is completed you can reboot the device.

If you have any issue in downloading “OpenGapps”, you can manually download this. All you have to do is go to this link and download the compatible file.

Configuring virtual device with Burp suite

So firstly you have to configure the proxy settings of the virtual device .

The next step is configuring Burp suite. Open Burp suite > Proxy > Options.
Add a new proxy listener.
Change the Port number to the same port number that is specified in the proxy settings of the virtual settings.
And change the “Bind to address” to “all interfaces”.

Now you completed the configuration in the Burp Suite.

The last step is to add a cacert to the virtual device.

Perfect! We successfully captured the requests from the virtual device.

Practical Time 🙂

Let’s discuss two vulnerabilities that have a high chance to be found in real world applications.

1. Hardcoding Issues

Hard-coding issues means developers hard-code some sensitive strings inside the source code. Hardcoded data might be password, access token etc..

Now we are going to connect to the device using adb.

adb connect [ip address : port]

You have successfully connected with the device. Next thing is to get the shell of the device. In order to do that run the following command:

adb shell

We are going to practice the testing on the application named DIVA (Damn Insecure and Vulnerable Application).

As you can see, diva is already installed in my device.

You can install apk using adb, for that use the following command:

adb install diva.apk

Now open diva app and click on the challenge named Hardcoding Issue Part 1.

So it is asking for a key for the users to access. When you type any value and click access it shows access denied.

So now you have to inspect the source code of the activity.

First, you need to unzip the apk.

unzip diva-beta.apk

As the next step, you have to read the contents inside the file “classes. dex” but it is not in a human-readable format. The next step is to convert the dex file to jar format, to do that you can use the d2j-dex2jar tool.

d2j-dex2jar classes.dex

After executing this command there will be a new file in .jar format.

jd-gui classes-dex2jar.jar

Here you can find the source code of every activity that is in the application. You are here to inspect the source code of the Hardcoded Issue, so open the corresponding file:

Here you can see that the developer hardcoded a sensitive string in the source code. So when the user enters any value in the box it validates with this key.

Now let’s enter this key in the box and see what happens.

These types of security vulnerabilities are known as Hard-coding Issues. That’s all about Hard-coding issues. Now you have to move to another vulnerability.

2. Insecure Data Storage

Insecure data storage means sometimes developers store sensitive information without encryption. Here the issue is storing user’s data like passwords, tokens in plain text cause any other application reads those sensitive data.

Let’s practice this on the diva.

We have opened the Insecure Data Storage challenge in diva.

Now we can save our credentials. For that, we entered a username and password and click save.

It says that credentials are saved successfully. Now let’s inspect the source code of the activity. To do that repeat the process we did the last challenge. That is open the .jar file using jd-gui.

We can see that the credentials are stored in the SharedPreferences folder.

So let’s navigate to that folder.

Now we are inside the package folder of the application diva. Inside this folder, there is the folder that we are looking for that is “SharedPreferences”. The source code of this application says that the credentials are stored inside this folder.

The next step is inspecting the contents of this folder.

We can see that there is one xml file. Let’s read the contents of this file

cat jakhar.aseem.diva_preferences.xml

Here we can see that the credentials that are entered are stored in plain text and also in insecure locations.
