Setup and Configuration

ADB (Android Debug Bridge)

ADB is a versatile command-line tool that allows you to communicate with a device. It is essential for various aspects of Android security testing.

Common ADB Commands:

adb devices # List connected devices
adb shell # Open a shell on the device
adb pull /sdcard/ # Pull files from the device
adb push <local> <remote> # Push files to the device
adb install <apk> # Install an APK on the device
adb uninstall <package> # Uninstall an APK from the device
adb logcat # View the system log
adb shell pm list packages # List installed packages
adb shell pm dump <package> # Dump the state of a package
adb shell am start -n <package>/<activity> # Start an activity
adb shell screencap /sdcard/screenshot.png # Capture a screenshot

Frida is a dynamic instrumentation toolkit used for reverse engineering and exploring the behavior of applications.

Common Frida Commands:

frida-ps -U # List processes on a connected device
frida -U -p <pid> # Attach to a process
frida -U -f <package> -l <script.js> # Inject a script into an application
frida-trace -U -i '<function>' <package> # Trace specific functions

Java.perform(function () {
    var MainActivity = Java.use('com.example.app.MainActivity');
    MainActivity.someMethod.implementation = function () {
        console.log('someMethod called');
        return this.someMethod.apply(this, arguments);
    };
});

Dynamic Analysis

Dynamic Analysis Tools

• Frida: Use Frida for real-time instrumentation and manipulation of app behavior.

• Burp Suite: Utilize Burp Suite for intercepting and analyzing HTTP/HTTPS traffic.

Common Dynamic Analysis Techniques

• Network Traffic Analysis: Inspect and manipulate network traffic to identify security issues such as sensitive data leakage.

• Code Injection: Test for code injection vulnerabilities using Frida scripts or other tools.

• Runtime Analysis: Observe app behavior and interactions during runtime to identify potential vulnerabilities.

Vulnerabilities Covered by MobSF

MobSF (Mobile Security Framework) provides automated analysis for various vulnerabilities:

• Insecure Data Storage: Detection of sensitive data stored insecurely on the device.

• Insecure Communication: Identification of unencrypted or poorly encrypted network traffic.

• Insecure Code: Analysis of code for insecure coding practices and vulnerabilities.

• Improper Platform Usage: Detection of misuse of platform features or permissions.

• Code Injection: Identification of potential code injection points.

Android Red Teaming

Android Red Teaming involves simulating real-world attacks to test the security posture of Android applications and devices.

Techniques and Tools

• Exploitation of Vulnerabilities: Use identified vulnerabilities to gain unauthorized access or control.

• Social Engineering: Employ social engineering techniques to trick users into revealing sensitive information or installing malicious apps.

• Persistence Mechanisms: Analyze and test for persistence mechanisms to maintain access to the device.

• Privilege Escalation: Identify and exploit weaknesses to escalate privileges on the device.

• Root/Jailbreak Detection: Test for the app’s ability to detect and respond to rooted or jailbroken devices.
