DROZER

DROZER: A MAPT TOOL

Drozer, short for "Android Security Assessment Framework," is a powerful open-source mobile application security testing tool primarily designed for Android applications. It is widely used by security professionals and penetration testers to assess the security of Android apps and identify vulnerabilities that could potentially be exploited by malicious actors.

Drozer provides a comprehensive set of features for dynamic analysis of Android applications. It allows testers to interact with an Android app at runtime, examining its behavior, data storage, and network communication. Drozer can perform tasks like identifying insecure data storage, discovering exposed components, and even simulating attacks to assess an app's resilience against various security threats. It also offers a scripting interface that allows testers to automate tasks and create custom test scenarios for in-depth security assessments.

One of the notable features of Drozer is its ability to establish a connection between the tester's machine and the target Android device, making it easier to analyze and manipulate app behavior in real-time. This tool is an essential resource for professionals concerned with Android app security and helps in uncovering vulnerabilities before they can be exploited by malicious hackers.

CHARACTERISTICS:

Drozer, the Android Security Assessment Framework, exhibits several key characteristics that make it a valuable tool for assessing the security of Android applications:

1. Dynamic Analysis: Drozer specializes in dynamic analysis, allowing testers to interact with Android applications in real-time. This means it can actively inspect an app's behavior, communication with external services, and data storage, providing valuable insights into its security posture.
2. Vulnerability Detection: Drozer is equipped with a wide range of modules and scripts that can automatically identify vulnerabilities and weaknesses in Android applications. It can detect issues such as insecure data storage, exposed components, and improper handling of sensitive information.
3. Scripting Capabilities: Drozer supports scripting, enabling testers to automate tasks and create custom test scenarios. This flexibility allows for the efficient and repeatable testing of Android apps, making it a powerful tool for security professionals.
4. Real-Time Interaction: The tool facilitates real-time interaction with the Android device under assessment. Testers can manipulate app behavior, simulate attacks, and observe the consequences immediately, enhancing their ability to identify security weaknesses.
5. Connection to Target Devices: Drozer can establish a connection between the tester's machine and the target Android device. This connectivity simplifies the assessment process and enables more comprehensive security testing.
6. Community-Driven: As an open-source project, Drozer benefits from contributions and updates from the security community. This means it can stay up-to-date with the latest Android security issues and testing techniques.
7. Cross-Platform Compatibility: Drozer is designed to work on multiple platforms, making it accessible to a wide range of security professionals and researchers.

STEPS TO INSTALL DROZER

Step 1: Drozer requires python version 2.7.18.

Step2: Drozer requires few pip libraries. Navigate to the recently installed Python version 2.7.18 directory, open cmd and runt the following commands:

python.exe -m pip install protobuf

python.exe -m pip install pyopenssl

python.exe -m pip install twisted

python.exe -m pip install service_identity

Step3: Download drozer from the following link: https://labs.withsecure.com/tools/drozer

Your system will tell you there is ransomware. Download it anyway and move it in the python folder which we downloaded earlier to resolve all the errors.

Step4: Installation of Drozer starts from here. Open Drozer Installer and follow the steps given in the screenshots.

Here, give the path of python 2.7.18.

Step5: Run the following command in cmd to check if the installation is done or not: drozer

Drozer has been setup. Now let’s install Drozer-agent on android device.

Step6: Download Drozer-agent from the following link: https://labs.withsecure.com/tools/drozer

And install it in your android phone.

Step7: Run the following command in cmd: abd forward tcp:31415 tcp:31415

Step8: Run the following command to connect drozer with your phone: drozer console connect

VULNERABILITES DETECTED BY DROZER

Drozer, like any security assessment tool, is designed to identify vulnerabilities and weaknesses in Android applications. Here are some common vulnerabilities that Drozer can help detect:

1. Insecure Data Storage: Drozer can identify instances where sensitive data, such as login credentials or personal information, is stored in an insecure manner, like in plain text files or unprotected databases. This vulnerability could lead to data breaches if exploited.
2. Exposed Components: It can discover exposed Android components, such as activities, services, or broadcast receivers, that should not be accessible to external or unauthorized apps. This can prevent attackers from exploiting these components to gain unauthorized access or control.
3. Improper Permissions: Drozer can detect instances where an app requests overly broad permissions, granting it unnecessary access to device resources. This could lead to privacy issues or potential misuse of user data.
4. Insecure Network Communication: The tool can identify insecure network communication practices, such as sending sensitive data over unencrypted connections. This vulnerability can expose user data to interception by malicious actors.
5. SQL Injection: Drozer can detect SQL injection vulnerabilities in an app's database interactions. SQL injection can allow attackers to manipulate the app's database and potentially access or modify sensitive data.
6. Insecure WebView Configuration: It can identify apps that use WebView components with insecure configurations, potentially exposing them to various web-based attacks, like Cross-Site Scripting (XSS) or Cross-Site Request Forgery (CSRF).
7. Authentication and Session Management Issues: Drozer can help identify problems related to authentication and session management, such as insecure login mechanisms or insufficient session timeouts, which could lead to unauthorized access.
8. Code Execution Vulnerabilities: It may identify code execution vulnerabilities, like remote code execution or command injection, which can allow attackers to execute arbitrary code on the device or compromise the app's functionality.
9. Lack of Input Validation: Drozer can reveal instances where user inputs are not properly validated, potentially leading to security flaws like buffer overflows, injection attacks, or other input-related vulnerabilities.
10. Insecure Code Practices: The tool can highlight insecure coding practices, such as the use of deprecated or unsafe APIs, which could introduce vulnerabilities into the app.

Drozer's ability to detect these and other vulnerabilities makes it a valuable asset for security professionals and developers who want to enhance the security of their Android applications by identifying and addressing potential weaknesses before they can be exploited by malicious actors.
