These modules are designed to examine application components and identify potential vulnerabilities.
Before you start working on a module, you must launch the target application using the command run app.package.start<package_name> or run the application analysis using the command run app.package.launch <package_name>. Drozer uses these commands to thoroughly analyze the application’s permissions, activities, and other security parameters.
During the analysis process, Drozer can reveal leaks in content providers with commands such as run scanner.provider.finduris, or intent-based vulnerabilities with the command run app.activity.start –component <package_name><activity_name>. This allows application developers and pentesters to evaluate access control mechanisms and other security measures.
For students, Drozer is an excellent resource for improving practical skills as well as conceptual knowledge. By preparing realistic scenarios during the training process, it is possible to discover potential vulnerabilities and better understand the Android security ecosystem.
Methods for Identifying Security Vulnerabilities
The methods used in penetration testing of mobile applications are divided into two categories: static and dynamic analysis. Static analysis is performed by thoroughly examining the source code of the application. Dynamic analysis, on the other hand, is carried out by observing the behavior of the application during runtime. Both methodologies are used together to enable a comprehensive security review.
However, automation tools are of great importance in penetration testing. Automatic tools save time and effort and reduce human error. The use of such tools is essential to increase the efficiency and accuracy of the security analysis process.
Methods used to find security vulnerabilities in applications include fuzz testing, reverse engineering, network traffic analysis, and penetration testing. These methods are used to detect security issues such as memory leaks, unauthorized access, and data disclosure. This makes applications much more secure.
For penetration tests to be carried out successfully, it is also very important to integrate DevSecOps practices that cover the development and release processes of the application. Subjecting an application to continuous security testing throughout its life cycle allows potential security vulnerabilities to be detected and corrected at an early stage. Ideally, security testing should be completed in full before an application is released to an app store.

Frida: Dynamic Analysis and Security Reviews
Frida is a hooking tool that allows real-time analysis and manipulation of mobile applications. This dynamic binary analysis platform enables security researchers to monitor, modify, and detect errors in the code of an application during runtime using JavaScript or C++. With its wide range of functions, Frida provides a flexible environment for security researchers to perform in-depth analysis on mobile applications.
When developing strategies to improve application security, it is necessary to review general security policies as well as dynamic analysis tools. Our article, “How to Develop Application Security Strategies,” provides comprehensive guidance on this topic.
Using Frida scripts, you can go beyond static analysis and observe the behavior of applications during runtime and interactively find potential security vulnerabilities. This approach is a godsend for cybersecurity experts racing against time, as dynamic analysis enables security vulnerabilities to be identified much more quickly and effectively. Furthermore, Frida also makes valuable contributions to reverse engineering processes, being used by developers and pentesters to bypass security barriers at critical points.
How does Frida work?
Frida provides analysis capabilities by intervening in applications running on mobile devices during runtime. It can access and modify the software code regardless of the operating system and application type. This method is ideal for dynamic analysis and hooking.
The working principle is script-based, allowing you to monitor and influence the runtime behavior of the target application using JavaScript code (or C++ APIs) for analysis. Real-time data can be collected while the application is running, and this data is used to identify security vulnerabilities. To do this, Frida’s powerful functions are utilized.
Frida’s effectiveness is demonstrated by bridging the gap between system-level flexibility and high-level application interfaces. It can be used effectively in both low-level (e.g., operating system kernel or hardware access) and high-level (e.g., application code or user interface interactions) analyses. This feature makes it possible to perform multi-layered security testing.
Frida also offers significant advantages in debugging and reverse engineering processes. By examining the memory management of the target application, it enables root cause analysis of security vulnerabilities and potential memory issues. This plays a critical role, especially in security testing of complex applications.
Unlike other analysis tools, Frida scripts allow detailed intervention in almost every aspect of the application, from which function is called when to which data is passed when. This enables security experts to gain detailed insight into the target application and shape their security strategies accordingly.
Hooking Techniques on Mobile Applications
Hooking offers critical capabilities in security analysis of mobile applications; it provides the ability to monitor and modify runtime behavior. These techniques are indispensable for detecting security vulnerabilities.
Hooking techniques form the basis of dynamic analysis processes. They enable the manipulation of method calls in mobile applications.
Especially in dynamic code analysis and vulnerability hunting, overriding functions or modifying input/output parameters during runtime is effective in revealing potential vulnerabilities. This can be done without disrupting the normal behavior of the application, which ensures that the analysis remains hidden.
The expected behavior and security controls of the application can be bypassed through hooking, which enables the simulation of high-privilege processes and the circumvention of protection mechanisms such as firewalls and permission management during the testing process. The changes made are important for understanding under what conditions the application is vulnerable in security analyses, for example, through SSL pinning bypass or method hooking.
