According to a 2024 mobile app security analysis, 75% of mobile applications contain at least one security flaw. Cybercriminals constantly look for weaknesses in mobile applications to steal data, exploit systems, or damage brand reputation. That’s where Mobile Application Penetration Testing (Mobile App Pentesting) comes in. It helps businesses identify vulnerabilities in mobile apps before attackers can exploit them, ensuring your mobile app stays secure, compliant, and trusted by users.
What Is Mobile Application Penetration Testing?
Mobile Application Penetration Testing is a security assessment process used to detect vulnerabilities in Android, iOS, web, and hybrid apps. Security experts simulate real-world cyberattacks to evaluate how well the app can withstand unauthorized access or data theft. The test examines every component of your mobile app from APIs to backend servers, ensuring that no loophole is left unchecked.
Types of Mobile Application Penetration Testing Based on Application Type
Every mobile application is built differently. That’s why penetration testing also varies depending on the type of app your business uses. Let’s understand how security testing differs for Native, Web, and Hybrid mobile apps.
1. Native Apps (Android/iOS)
Native applications are built specifically for a single operating system — such as Android or iOS. They use platform-specific languages like Java/Kotlin (Android) or Swift/Objective-C (iOS). Because they have deep access to device hardware and features, they also carry unique security risks.
Penetration testing for native apps focuses on:
- Detecting insecure data storage in local databases or app containers.
- Checking for improper permissions or access controls.
- Testing encryption of sensitive information stored on the device.
- Identifying risks in APIs that connect the app to backend servers.
- Preventing reverse engineering or tampering with application code.
Goal: To ensure the app is secure even if the device is compromised.
2. Mobile Web Apps
Mobile web applications run through browsers like Chrome or Safari and don’t need installation from an app store. They are built using web technologies such as HTML5, CSS, and JavaScript. Since they rely on internet connectivity, web app testing focuses more on server-side vulnerabilities and data transmission security.
Penetration testing for mobile web apps includes:
- Identifying injection flaws such as SQL Injection and Cross-Site Scripting (XSS).
- Testing session management and cookie handling.
- Ensuring HTTPS encryption is properly implemented.
- Detecting misconfigurations in hosting environments.
- Validating authentication and authorization mechanisms.
Goal: To prevent attackers from exploiting server or browser-based vulnerabilities.
3. Hybrid Apps
Hybrid applications combine elements of both native and web apps. They are developed using frameworks like React Native, Flutter, or Ionic and then wrapped in a native container.
While hybrid apps save development time, they introduce a mix of vulnerabilities from both native and web environments. Penetration testing for hybrid apps involves:
- Checking for insecure communication between the app and web components.
- Testing local data storage and file system access.
- Validating secure use of APIs and third-party plugins.
- Assessing exposure to JavaScript injection or cross-platform risks.
- Ensuring the app cannot be reverse engineered easily.
Goal: To maintain consistent security across both native and web layers of the application.
Each application type demands a unique testing approach. Partnering with a professional cybersecurity firm like Peneto Labs ensures your mobile app native, hybrid, or web-based are thoroughly tested against every possible threat.
Types of Mobile Application Penetration Testing Based on Methodology
Mobile application pentesting involves several methods based on the app’s architecture, operating system, and data flow. Here are the main types of testing used by cybersecurity professionals:
1. Static Application Security Testing (SAST)
Static Application Security Testing (SAST) focuses on identifying security flaws before the application is run.
It works by analyzing the source code, bytecode, or binaries to detect vulnerabilities early in the development stage. SAST is often referred to as “white-box testing” because the tester has full visibility into the application’s internal structure and logic.
How SAST Works?
- The source code of the mobile app is scanned using automated tools.
- These tools look for common coding errors, insecure functions, and vulnerable libraries.
- Developers get detailed reports highlighting the exact lines of code that need fixing.
Key Focus Areas of SAST
- Detecting hardcoded credentials, API keys, and secrets.
- Identifying injection flaws like SQL or command injection.
- Finding improper input validation and insecure data storage issues.
- Checking compliance with secure coding standards.
- Highlighting vulnerable third-party dependencies.
Benefits of SAST
- Early Detection: Catches vulnerabilities before the app reaches production.
- Developer Empowerment: Helps teams adopt secure coding practices.
- Low Cost: Fixing code issues early saves money later in development.
- Compliance Ready: Supports frameworks like OWASP, ISO 27001, and GDPR.
2. Dynamic Application Security Testing (DAST)
Dynamic Application Security Testing (DAST) takes a different approach- it tests the application while it’s running. It simulates real-world attacks to uncover vulnerabilities that only appear during execution. DAST is known as “black-box testing” because the tester does not need access to the source code.
How DAST Works
Testers interact with the running mobile app just like a real user or hacker would.
The DAST tool sends various inputs, payloads, and requests to the app. The system monitors how the app responds to identify security misconfigurations or runtime vulnerabilities.
Key Focus Areas of DAST
- Detecting authentication and authorization weaknesses.
- Identifying cross-site scripting (XSS) and injection attacks.
- Testing for session management flaws and API security gaps.
- Verifying error handling and response security.
- Ensuring encryption standards are properly implemented.
Benefits of DAST
- Real-World Testing: Mimics hacker behavior for realistic results.
- No Source Code Required: Ideal for third-party apps or legacy systems.
- Broad Coverage: Detects runtime vulnerabilities missed during development.
- Continuous Monitoring: Can be integrated into DevSecOps pipelines.
3. Interactive Application Security Testing (IAST)
Interactive Application Security Testing (IAST) is an advanced testing method that works by analyzing applications in real time while they are running.
Unlike traditional static or dynamic tests, IAST provides continuous visibility into how your mobile app behaves under real-world usage. It combines the best of both Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) making it a hybrid and highly accurate approach.
How IAST Works
- IAST tools are integrated into the application runtime environment (during testing or QA phase).
- They monitor the app’s internal behavior as testers interact with it.
- The system observes data flow, logic execution, and API communication to identify weaknesses.
Key Focus Areas of IAST in Mobile Application Testing
- Detecting vulnerabilities in real-time while the app executes.
- Finding insecure coding practices that SAST might miss.
- Identifying runtime issues such as authentication flaws or API misuse.
- Testing the effectiveness of existing security controls.
- Providing detailed insights about the exact location of vulnerabilities in the source code.
Benefits of IAST
- High Accuracy: Fewer false positives compared to traditional methods.
- Real-Time Feedback: Vulnerabilities are detected instantly during execution.
- Developer-Friendly: Provides actionable insights directly linked to code lines.
- Continuous Security: Works well with CI/CD pipelines, making it ideal for agile development.
- Cost-Effective: Detects and helps fix issues early in the development cycle.
4. API Security Testing
Most mobile apps rely on APIs to connect with servers. API testing ensures these communication channels are properly secured and do not expose sensitive information.
5. Network Security Testing
This testing checks how the app interacts over Wi-Fi, mobile data, and backend servers. It ensures data encryption and prevents man-in-the-middle attacks.
6. Reverse Engineering Testing
This test checks if an attacker can decompile or tamper with the app. It helps prevent intellectual property theft and unauthorized code modification.
