C12 Content Provider Discovered Undiscovered
Content providers in Android are used to share data between applications. They use standard insert, update, delete, and query methods to access data and are assigned a special URI starting with "content://". If proper security controls are not implemented, it can lead to the leakage of information. An example of a content provider is the built-in SMS application, which can be accessed by other apps using a specific URI and the READ_SMS permission. There may be cases where content providers are not implemented for sharing data or where access is restricted to apps with proper permissions.
1 If security controls are not properly implemented, content providers can lead to SQL injection.
2 If security controls are not properly implemented, content providers can lead to Path Traversal.
3 If security controls are not properly implemented in content providers, it may lead to internal data access vulnerability

C15 Insecure Coding Practice Discovered Undiscovered
Insecure coding practice refers to the use of coding techniques or practices that do not adequately protect an application or system from security vulnerabilities or threats, such as using weak passwords or failing to properly validate user input. Insecure coding practices can make an application or system more susceptible to attacks or data breaches. To prevent insecure coding practices, developers should follow best practices for secure coding and regularly review and test their code for vulnerabilities.
1 Check for use of Insecure Random Number Generator functions (Like generating guessable OTP)
2 Check for use of Insecure functions or insure functions/objects calling
3 Uses of weak cryptography or easily reversible encryption method (like MD5 Hash, Base64 Encoding)

Understanding Vulnerabilities: Definitions and Mitigations

SSL Pinning

Definition:
SSL (Secure Socket Layer) pinning in Android is a security measure where a mobile app validates a server's SSL certificate against a pre-defined certificate or public key embedded within the app. This helps prevent man-in-the-middle attacks by ensuring a secure and trusted connection.

Explanation:
Scenario A: An Android Application with No SSL Pinning
In this scenario, an Android device relies on its own 'Trusted Credential' list, which contains all primary trusted root certificates. Suppose you developed an Android application that checks the wallet balance of your e-commerce service. When the app communicates with your e-commerce service (e.g., through an API call), the device verifies the service's SSL certificate against its 'Trusted Credential' list.
$\quad$ The problem arises if a hacker intercepts the connection and pretends to be your e-commerce service using a valid SSL/TLS certificate. In this case, both the Android device and your app could be tricked into communicating with the hacker's fraudulent service.

Scenario B: An Android Application with SSL Pinning (Hardcoded Certificate)
In this scenario, your app has a hardcoded certificate for your e-commerce service. When the app makes an API call, the device still verifies the service's SSL certificate against its 'Trusted Credential' list. However, your app will also compare the server's certificate with the hardcoded one.
$\quad$ If a hacker intercepts the connection and pretends to be your e-commerce service with a valid SSL/TLS certificate, the device will perform its verification. Still, your app will recognize the mismatch between the hardcoded certificate and the presented one. As a result, the app will terminate the connection, thereby preventing communication with the malicious service.

Mitigations:
The general solution is to hardcode the SSL/TLS certificate of your web service directly into your Android app and validate the certificate with each web request.
For more information on implementing SSL pinning, you can refer to the Android Developer Guide on SSL and this helpful discussion on Stack Overflow.

Mobile Security Framework (MobSF)

Important

MobSF's Docker installation does not currently support dynamic analysis. If you only require static analysis, the Docker installation is straightforward. However, for dynamic analysis, it is recommended to install MobSF on a physical device.
In case of Windows installation MobSF requires some additional external dependencies. Please make your installation choice accordingly.

Update as on 17.10.2024:
I previously misunderstood the capabilities of the MobSF Docker. I wasn't aware that it supports dynamic analysis using the MOBSF_ANALYZER_IDENTIFIER flag. I recently discovered this feature and have been successfully using it in several application testing projects. Click Here to Read More about MobSF Dynamic Analyzer.

Bypassing permission denied issue while Get/Pull a File from an Android device using ADB:

# Solution 1:
adb shell su -c 'cat <file_path_and_name>' > <location_on_computer>

# Solution 2: Useful when to check, SharedPreferences is accessible as non-root (low-privileged) user or not
adb exec-out run-as <package_name_of_the_apk> cat /data/user/0/<package_name_of_the_apk>/shared_prefs/<file_name> > <location_on_computer>

# Solution 3: Useful when you need to access a apps internal files or a file that owned by the particular app (root required)
adb shell su -c 'run-as <package_name_of_the_apk> cat <file_path_and_name>' > <location_on_computer>

# e.g.:

# adb shell su -c 'run-as jakhar.aseem.diva cat /data/user/0/jakhar.aseem.diva/files/Test.txt' > Test.txt

Tip

run-as is a command that facilitates the execution of other commands with the permissions of a specific app on an Android device. This is essential for accessing app-specific data and resources that are normally restricted.

Syntax: adb shell run-as <package-name> <command> <args>
Example: adb shell run-as com.example.myapp cat /data/data/com.example.myapp/databases/mydatabase.db

Bypassing permission denied issue while Get/Pull a Directory from an Android device using ADB:

# Get a Directory from android device
dir="<directory_path_and_name>"; IFS=$'\n'; for subdir in $(adb shell su -c "find \"${dir}\" -type d"); do mkdir -p ".${subdir}"; done; for file in $(adb shell su -c "find \"${dir}\" -type f"); do adb shell su -c "cat \"${file// /\\\ }\"" > ".${file}"; done;

# e.g.:
# dir="somedir"; IFS=$'\n'; for subdir in $(adb shell su -c "find \"${dir}\" -type d"); do mkdir -p ".${subdir}"; done; for file in $(adb shell su -c "find \"${dir}\" -type f"); do adb shell su -c "cat \"${file// /\\\ }\"" > ".${file}"; done;
Breakdown of the command: (Click to expand)

Set Directory: dir="<directory_path_and_name>" assigns user provided value to the variable dir.

Set Separator: IFS=$'\n' sets the Internal Field Separator (IFS) to a newline for proper handling of filenames.

Create Directories: For subdir in $(adb shell su -c "find \"${dir}\" -type d") Iterates over subdirectories found by find on the Android device, creating corresponding directories (with dot prefix) in the current directory.

Copy Files: For file in $(adb shell su -c "find \"${dir}\" -type f") Iterates over files found by find, reads their contents using cat, and writes them to files with dot prefixes in the current directory.

Note

Keep in mind that, when using ADB, empty directories will not be copied from or to an Android device.

Frida Commands

List android packages using Frida:

# List all packages with PID, Names & Identifiers

# List PID, Name, Identifiers that match the input string
frida-ps -Uai | grep -i '<part_of_the_package_name>'

# e.g.:
# frida-ps -Uai | grep -i 'diva'

Tip

-D : Use this flag Connect Frida to the specific device (the device identifier you gate by running adb devices command)

Syntax: frida-ps -D <device_identifier>
Example: frida-ps -Uai -D 27d1d6d3a03 | grep -i 'diva'

Discover an app internal methods/calls using frida:

# Discover internal methods/calls of an app and save the output in a file

# e.g.:
# frida-discover -U -f jakhar.aseem.diva | tee frida_discover.txt

N.B: Here tee command part is optional, I recommended this for display and also save the output in a file which may required letter.

Trace an app internal methods/calls using frida:

# Trace all internal methods/calls of an app
frida-trace -p <pid_of_an_app>

# Trace specific(s) internal methods/calls of an app
frida-trace -p <pid_of_an_app> -i '<function_name>*'

# e.g.:
# frida-trace -p 852
# frida-trace -p 852 -i 'log*'

Tip

You can use -i flag multiple times as per your needs.
For example: frida-trace -p 852 -i 'log*' -i 'recv*' -i 'send*'

For more frida-trace commands please read the official documentation.

# e.g.:
# frida --codeshare fdciabdul/frida-multiple-bypass -f jakhar.aseem.diva

Tip

Sometime frida will give error like Failed to spawn or Failed to attach in that case use -D, -f, and -n together

frida -D <device_id> <script> -f <package_name_of_the_apk> -n <app_name>

# e.g:
# frida -D ede147ef --codeshare fdciabdul/frida-multiple-bypass -f jakhar.aseem.diva -n Diva

N.B: Frida automatically paused the target app when attaching. Using
--no-pause to prevent this, allowing the app to start normally while Frida injected the scripts.
