Is mobile application penetration testing right for you?
If you’re responsible for mobile app security, ask yourself:
Could someone exploit your app to access your network or sensitive data?
Are your APIs properly secured against real-world threats?
Does your app store personally identifiable information (PII) in its backend?
Would your clients or users value independent verification of your app’s security?
If you’re unsure about any of these, a mobile app pen test from CodeShield provides clarity, confidence, and a clear path to better security.

A closer look at our mobile app penetration testing process
1. Scoping
Our team works with you to define the objectives, scope, and approach for testing your mobile application. This includes identifying the platforms (iOS, Android), key application functionalities, APIs, and third-party integrations to be tested. The scope also covers areas such as authentication mechanisms, data storage, and communication channels. By understanding your app’s purpose and user base, we ensure the engagement aligns with your security goals and compliance requirements.
2. Intel Gathering
We begin by gathering information about the mobile application and its environment. This includes identifying the app version, platform, and associated APIs. We analyse the app’s permissions, third-party libraries, and publicly accessible endpoints. Reconnaissance may also involve reviewing the app’s metadata, back-end infrastructure, and user roles to map its attack surface. This phase helps identify initial points of interest for the subsequent testing stages.
3. Vulnerability Analysis
Our experts assess the mobile application for vulnerabilities by examining key areas such as insecure data storage, improper authentication, weak encryption, and flaws in API implementation. We evaluate both client-side (e.g., decompiling the app, analysing its code and logic) and server-side vulnerabilities. This includes testing for OWASP Mobile Top 10 risks, such as insecure communication, broken access controls, and reverse engineering risks, ensuring a comprehensive analysis of the app’s security posture.
4. Exploitation
In this phase, we exploit identified vulnerabilities to demonstrate their potential impact. For example, we may bypass authentication mechanisms, intercept sensitive data during transmission, or exploit backend APIs to manipulate application behavior. Exploitation is performed in a controlled environment to ensure the app’s integrity and the confidentiality of any sensitive data. This phase highlights the real-world impact of security flaws on both the app and its users.
5. Reporting
We compile a detailed report tailored to mobile application security. This includes descriptions of vulnerabilities, proof-of-concept (PoC) evidence, and their impact on the application and its users. The report provides actionable recommendations to remediate the issues, with a focus on secure coding practices and platform-specific guidelines. The findings are categorised by severity, helping your team prioritise remediation efforts effectively.
6. Debriefing
The engagement concludes with a debriefing session where we review the findings and discuss their implications with your team. We provide a walkthrough of the vulnerabilities, demonstrate potential exploitation scenarios, and recommend best practices for securing your mobile application. This interactive session ensures clarity and provides actionable guidance to strengthen the app’s security posture and protect user data.
Frequently asked questions (FAQs)
What is the focus of mobile app pen testing?
The focus is to provide a comprehensive analysis of the security features of the application and its back-end components. Mobile app tests have the aim of revealing vulnerabilities in the cyber security posture of the application with the goal to identify key areas where security can be improved.
How does mobile app testing work?
Testers will assess some key parameters of the app to ensure it meets quality and security standards, for the data it both processes and stores.
Some of these parameters include:
- Architecture and design.
- Network communication.
- Data storage and privacy.
- Authentication and session management.
- Misconfiguration errors in code or build settings.
By following these steps and using a combination of manual and automated testing techniques, mobile application pen testing ensures the apps meet minimum security requirements helping deliver a seamless user experience.
What vulnerabilities do we find in mobile apps?
We typically find a combination of the OWASP Mobile Top 10 vulnerabilities, which includes:
Will my business be disrupted during testing?
We can test against a non-production environment, such as a UAT/QA environment to make sure there is no risk to your live services. In the event this is not possible, the tester will take a more cautious approach to any post-exploitation testing.
How long does a test normally take?
All our tests are tailored to your specific requirements however as a guide most mobile applications including both iOS and Android take approximately 5 days to complete.
How often should I test mobile apps?
Implementing frequent mobile application testing into your software development life cycle is the best way to upkeep security. However, it is typically industry best practice to test your applications at least once a year and or before any major changes to the UI or software updates.
