What is mobile application penetration testing? Why is it important?

A mobile app pen testing is performed to identify any mobile application vulnerabilities that could lead to data loss. This security assessment, also known as mobile application security testing, is dynamic in nature, meaning it is conducted while the application is functioning. 

Our thorough security services concentrate on key areas of the mobile attack surface i.e. Reverse engineering, Data at rest, Data in transit, web services and APIs.

For a mobile application to support confidentiality, integrity and availability of a system and its data, a mobile application has to ensure cyber hygiene on many fronts with a mobile application security assessment. 

  1. Weak Server Side Controls are primary target because any communication outside the mobile devices occurs via server. 

  2. Insecure Data Storage as sometimes developers depend upon the client storage for data. This is commonly found in our mobile penetration testing services.

  3. Transport Layer Protection includes encrypted routes through which the data is transferred/received to/from the server. 

  4. A threat actor who can easily reverse the application code to find flaws that can be exploited, or injecting malware is a serious concern. Binary Protection is important to secure the mobile applications installed on phones.

  5. Data Leakage due to application bugs, residual data on the device or lack of secure coding practices.

Most importantly, don’t forget to get your mobile application independently validated against application controls.

Benefits of mobile app security penetration testing services

Our mobile app pen testing assesses real-world mobile app security vulnerabilities in a number of ways. One common approach is to reverse engineer the app to understand how it works and identify any potential vulnerabilities.

Another approach is to analyze the app’s traffic to see if there are any suspicious or untrusted requests being made. Finally, consider running a static analysis tool on the code to identify any potential issues.

By identifying potential security vulnerabilities in the mobile app design, our mobile application pentesting service can help to validate secure design best practices. For example, it helps to identify if any sensitive data is being stored insecurely on the device, if authentication methods are effective and if there are any loopholes that could be exploited by a malicious user.

The main benefit of mobile app pen testing is the increased flexibility and productivity it offers users. With this service, businesses can easily assess the security of their hybrid mobile apps and identify potential vulnerabilities. This helps them to safeguard their data and improve the overall mobile app security of their operations.

By using our mobile pen testing service, organisations can ensure that their authentication, authorisation, and encryption mechanisms are functioning properly. It simulate an attacker’s actions, allowing companies to test the security of their mobile apps and systems in a controlled environment.

A mobile pen test is an essential security measure to find and fix potential vulnerabilities in mobile apps and devices. By identifying weaknesses and improving security, organisations can avoid disastrous data breaches that could jeopardise customer information or Damage corporate reputation.

There are many compliance frameworks out there, each with their own specific requirements. Our mobile application security testing can help support your organisation’s compliance with mobile security framework such as PCI DSS and ISO 27001.

Types of Mobile Security Testing

Mobile App Pen Testing

A mobile application penetration test aims to identify flaws that would avoid data leakage or theft. Penetration testing for mobile applications ensures that different phases such as static analysis, network traffic analysis, authentication architectures, tampering, storage mechanisms, APIs are reviewed thoroughly.

Secure Code Review

Secure Code review is the process of manually reviewing the mobile application source code that would highlight issues missed during a black box pentest. A code review is a final go-ahead for an application just before the release. This assures that the code is secure and all dependencies are functioning as intended.

Mobile Device Security Review

Mobile application security assessment includes areas such as the management of the device, policies implemented, device configuration, and the mobile apps used on the device. Based on whether BYOD (Bring Your Own Device), or company owned device, reviews are performed to identify gaps linked with security risks.

Accreditations & Certifications

OWASP Top 10 mobile pentesting vulnerabilities

Any violation of published guidelines or functionality misuse such as excessive permissions usage.

It may include platform permissions, TouchID misuse, keychain secrets or other mobile OS features specific to an iOS device or android apps.

Data stored insecurely includes examples such as SQL databases, log files, binary data stores, cookies, SD card, cloud synched. This could also relate to unintended data leakage vulnerabilities from the operating system, frameworks, hardware or rooted/jailbroken devices.

Anything related to insecure data transmission between two points. This data transmission could encompass mobile to mobile communications and application to server communications and data encryption risks related to technologies in use.

Authentication vulnerabilities are one of the critical attack vectors for a cyber criminal. This phase includes assessing authentication mechanism, transmission channels, nature of input, insecure configurations, weak credentials & bypass attempts.

Insecure use of cryptography is common in mobile applications leveraging encryption. Business impact of such issues could lead to privacy violations, information theft, IP theft or reputational implications.

Whether it is possible to access unauthorised functionality by exploiting Insecure Direct Object Reference (IDOR) vulnerabilities, hidden endpoints.

Insecure coding practices cause security impacts where application code and the device side of mobile application is affected.

Whether an application performs code integrity checks to prevent code tampering and modifying at an attackers’ will. Mobile applications developed for certain business verticals may have severe implications of code modification such as in gaming sector, compared to others.

Due to the inherent nature of the code, most applications can be reverse-engineered. Although this helps an attacker to understand the underlying code, an application must ensure various defences to avoid IP theft or allow exploitations of any vulnerabilities.

Any hidden or undocumented features that can be identified and exploited to gain access to underlying systems hosting vulnerable code.

The above list covers the main tools, however, this is not the comprehensive list used during every mobile security assessment. OWASP has released a Mobile Security Testing Guide (MSTG), which covers the types of attacks that can be launched against mobile applications and how to test for them. This guide is intended for security professionals who want to assess the security of mobile apps, and it provides specific instructions on how to do so.

Security testing on mobile applications provides you an accurate view of risks affecting your mobile applications, supporting APIs that may be common to web applications or even the backend issues. This helps to assess, analyse and mitigate security risks. 

Mobile Application Penetration Testing Methodology

We are a UK based mobile app penetration testing company. Our mobile application penetration tests are designed to ensure thorough review to identify, analyse and exploit security vulnerabilities in applications and devices. Whether it’s android mobile apps security testing or iOS based, initial security methodology for mobile application penetration test involves similar fundamentals.

Some test cases are generating during the mobile application security testing dependent upon the functionality of the application. In mobile app pentesting, review of devices is equally important to analyse application settings, configuration files and any residual data. This mobile application security testing services ensures a holistic review of device and app.

Scoping and Customer Insight

When you decide to give us the go-ahead for mobile penetration testing, our very first step is to gain insight into your motivation, so that we can advise on your real concerns.

The comprehensive process we go through to understand this determines the vision for the project. At the technical level, this includes assets to be included, their fragility and importance to the environment.


Based on the response received from the reconnaissance phase, the target list for mobile app penetration testing is prioritised. The priority would be based on “low-hanging” fruit that could aid in gaining a foothold within the network trivially.

OWASP Mobile Top 10

Our consultants would focus on the top 10 categories of mobile security attacks defined by the industry-standard OWASP. This includes areas such as platform misuse, insecure communication, encryption vulnerabilities, injection issues such as SQL injection, XSS, XXE, insecure authentication and authorisation flaws and any code tampering issues.

Web Server Analysis

Web server hosting of the android and ios apps is also considered a vital component during mobile app testing.

A weakness in supporting infrastructure including the configuration of the webserver could lead to a slight compromise of the application hosted on it.

API Analysis

Modern mobile applications (including mobile) rely on API’s for their features / functionalities. Once the endpoints are identified – during network as well as static analysis – these would be further assessed. Weak endpoints could lead to trivial functionality bypass or sometimes, potential denial of service scenarios.

Local file / storage analysis

Following the initial run, the app would create several files / data which would be stored in the app folder on the device. These files would be analyzed in our mobile application penetration test is to understand the storage mechanism. 

This analysis would reveal if any app sensitive data including session management tokens, passwords are stored in clear text on the device itself.

Thorough Analysis and Reporting

Our reports are comprehensive and include all the evidence that supports our findings. We give you a risk rating that considers how likely an attack is as well as the impact it could have. We don’t create panic scenarios.

Our mitigation is detailed, covering both strategic and tactical areas to help our clients prepare a remediation plan.
