    What is a Mobile Application Penetration Test?

    Mobile Application Penetration Testing is a crucial process that aims to identify and rectify vulnerabilities within mobile applications before they can be exploited for malicious purposes. This testing can be conducted manually or through automated penetration testing tools to analyse the severity of threats posed by identified vulnerabilities.

    Mobile App Penetration Testing typically adheres to a structured methodology, employing industry-standard techniques and procedures that are diligently followed by a proficient penetration tester. By conducting this rigorous security examination, organisations can proactively strengthen their mobile apps’ security and protect sensitive user data from being compromised.

    Common Mobile Application Security Vulnerabilities

    Improper Credential Usage

    This vulnerability arises when applications handle user credentials insecurely. Common issues include storing passwords in plain text, hardcoding credentials within the application, and transmitting credentials without encryption.

    Inadequate Supply Chain Security
    Applications often rely on third-party libraries and components. Inadequate supply chain security involves the failure to vet these external dependencies for vulnerabilities. Outdated components can introduce critical security risks.
    Insecure Authentication or Authorisation
    Insecure authentication and authorisation mechanisms fail to verify user identities and control access to resources properly. Issues include weak password policies, lack of multi-factor authentication (MFA), and insufficient session management.
    Insufficient Input/Output Validation
    This vulnerability results from failing to validate input and output data properly. Applications that do not sanitise inputs are open to attacks such as SQL injection, cross-site scripting (XSS), and buffer overflows.
    Insecure Communication
    Insecure communication refers to transmitting sensitive data over unencrypted channels or using weak encryption protocols. This makes it possible for attackers to intercept and manipulate data in transit.
    Inadequate Privacy Controls
    This vulnerability involves improperly handling personal data, leading to privacy violations. Issues include excessive data collection, lack of user consent, and inadequate data storage protections. Failure to implement strong privacy controls can result in unauthorised data access and breaches, compromising user privacy and trust.

    What are the benefits of Mobile Application Security Testing?

    The proliferation of mobile applications spans various personal and business uses, encompassing sectors like entertainment, finance, communication, and more, thereby necessitating robust mobile application security. The benefits of mobile application penetration testing are manifold, including:

    Mobile Application Penetration Testing Methodology

    The methodology of Mobile Application Penetration Testing is structured and follows established standards to ensure a thorough examination of mobile applications. The Open Web Application Security Project (OWASP) provides a solid foundation for this through its Mobile Application Security Verification Standard (MASVS), Mobile Security Testing Guide (MASTG), and Mobile App Security Checklist. Our security testers use the MASTG as a basis for conducting a mobile app penetration test

    The Mobile Application Security Verification Standard (MASVS) organises security controls into distinct groups, each labelled as MASVS-XXXXX, targeting critical areas of the mobile attack surface. Here’s a breakdown of these control groups and a brief description of each:

    Ensures the secure storage of sensitive data on the device, safeguarding data-at-rest from unauthorised access.

    Utilises cryptographic functions to shield sensitive data, ensuring it remains inaccessible to malicious actors.

    Implements robust authentication and authorisation mechanisms within the mobile app, ensuring only authorised entities can access critical functionalities.

    Ensures the secure transmission of data between the mobile app and remote endpoints, protecting data-in-transit from interception and tampering.

    Manages secure interactions between the mobile app, the underlying mobile platform, and other installed apps, preventing potential security risks.

    Adheres to security best practices for data processing and app maintenance, ensuring the app remains updated and secure against emerging threat

    Enhances the app’s resilience to reverse engineering and tampering attempts, ensuring the integrity and confidentiality of the app and its data.

    Frequently Asked Questions: Mobile Application Security Testing

    Take a look at our frequently asked questions and find the answers you’re looking for, our FAQ provides clear and concise responses to common inquiries.
    Why is mobile application security testing important?

    Globally, there are nearly 9 million mobile apps hosted across platforms like the Apple App Store™ and Google Play™; organisations are compelled to ensure the robust security of their mobile applications against a diverse range of cyber threats.
    Mobile application penetration testing is a pivotal process that scrutinises mobile apps to detect and identify vulnerabilities before they can be exploited for malicious gain. This process, which can be executed through manual or automated penetration testing, analyses the severity posed by potential threats to the application.

    Recent data breaches, such as those experienced by Twitter, T-Mobile, and LinkedIn, underscore the criticality of securing mobile applications against potential threats and vulnerabilities. These incidents have exposed millions of users’ personal data and highlighted the significant risks posed by security flaws in mobile apps.

    Types of mobile applications to consider getting tested:

    Native Mobile Apps: Developed for specific platforms like Android or iOS, using languages such as Java, Kotlin, Swift, and more.

    Hybrid Apps: Combining elements of both iOS and Android applications, they can be downloaded from various app stores.

    Progressive Web Apps (PWA): Web apps that function like mobile apps, providing a seamless user experience across platforms.

    Who should get a Mobile App Penetration Test?

    Every mobile application, irrespective of its use and audience, should be developed with a security framework in mind. The necessity for a penetration test, however, can be contingent upon the nature and sensitivity of the data managed by the application and its associated databases. OWASP MASVS offers several levels of testing, detailed below:

    Here’s a bit more detail about each level:

    MASVS-L1 (Standard Security): Serving as the foundational security benchmark, this level mandates that all mobile applications comply with essential security controls, addressing fundamental aspects like data security, network communication integrity, and rudimentary system interactions.

    MASVS-L2 (Defense-in-Depth): This tier is tailored for applications that manage more sensitive data and functionalities. It demands exhaustive threat modelling and security verification, enveloping all controls from L1 while introducing additional ones to mitigate more sophisticated attacks.

    MASVS-R (Resiliency Against Reverse Engineering and Tampering): This level is designed for applications that navigate through highly sensitive data and are susceptible to advanced client-side attacks. It amalgamates all controls from L2 and fortifies them with additional measures to shield against client-side vulnerabilities, such as tampering and reverse engineering.

    Does OWASP apply to mobile application security?

    Because mobile applications differ from web applications, evaluating them requires a new approach.

    OWASP-MASVS was created primarily to help penetration testers discover mobile application security vulnerabilities. This can comprise a variety of strategies aimed at protecting mobile apps against various forms of cyber threats.
