Use Case

Mobile app security testing protects your mobile applications against security & privacy risks

Mobile Application Security Testing (MAST) is the process of analyzing mobile apps—during development and after release—to identify security vulnerabilities, misconfigurations, and privacy risks. It’s a foundational part of modern mobile app security testing, especially as mobile apps handle sensitive data, integrate with backend systems, and interact directly with user devices.

Why mobile application security testing matters

Mobile development teams are under pressure to move fast—delivering new features, fixes, and updates on tight deadlines. But when security teams can’t keep up, vulnerabilities go undetected and the risks reach customers, auditors, and production environments. That’s why leading organizations are embedding automated mobile app security testing into their development pipelines to secure every build, without slowing down delivery.

Common mobile app security threats

Hardcoded credentials and secrets
exposed in the binary

Insecure data storage,
including unencrypted files and logs on the device

Weak or broken TLS configurations
allowing for MITM attacks

Improper use of platform permissions 
and privacy-violating SDKs

Unprotected APIs 
exposing sensitive functionality or user data

Debug settings or test modes 
accidentally included in production builds

Inadequate session management
leading to unauthorized access

Susceptibility to tampering
including app repackaging or hooking

Exposure to reverse engineering,
revealing sensitive logic, API keys, or proprietary IP

Benefits of comprehensive mobile app security testing

Comprehensive mobile app security testing gives your team full visibility, control, and assurance—without slowing down development, providing:

Full visibility into what you’re actually shipping

Analyze the final mobile binary—not just source code or build configs—to catch issues hidden during compilation and packaging

Actionable findings for developers—not noise

Prioritized, contextual results help dev teams remediate quickly, without parsing generic scanner output

Runtime behavior insights and SDK analysis

Understand how apps behave once deployed—including data storage, API usage, and third-party SDK behavior

Built-in compliance alignment

Map findings directly to frameworks like OWASP MASVS, PCI DSS, HIPAA, and internal policies—with exportable reports

Faster, safer release cycles

Test every build in CI/CD, reduce rework, and minimize last-minute security delays

Lower security and operational costs

Reduce breach risk, avoid regulatory fines, minimize rework, and cut reliance on expensive manual testing or external consultants

Key components of a mobile application security testing solution

Code analysis (SAST)

Analyzes source code to detect vulnerabilities early in the development cycle. Foundational for identifying insecure logic, API misuse, and hardcoded secrets before they become embedded in release builds.

Dynamic testing (DAST)

Examines the app while it’s running to uncover issues that only surface during execution, such as flawed authentication, session management flaws, or runtime data leaks.

Interactive testing (IAST)

Interactive application security testing (IAST) is a hybrid security testing approach that works by embedding security agents inside the application runtime environment, allowing real-time analysis of code execution, API calls, and user interactions.

Forced-path execution

Forced path execution simulates key user flows and triggers code paths that are often skipped in normal testing—like those behind logins, feature flags, or admin settings. It uncovers hidden vulnerabilities that static scans and manual reviews usually miss.

Network communication testing

Analyzes how the app communicates with backend services to detect insecure data transmission. Identifies risks like plaintext traffic, weak or misconfigured TLS, exposed API endpoints, and susceptibility to man-in-the-middle (MITM) attacks.

Data storage security

Evaluates how sensitive data is stored locally on the device. Ensures encryption is properly implemented and confirms that logs, caches, and local files aren’t exposing confidential information to unauthorized access.

Post-deployment monitoring without SDKs or agents

Allows ongoing assessment of live App Store builds without embedding code or relying on user devices. Maintains visibility post-release with zero user impact

Platform-specific security testing

Addresses the unique security rules, risks, and behaviors of each platform (iOS and Android) to ensure nothing is missed. Delivers accurate results for both iOS and Android apps, no matter how they’re built or deployed.

Automated MAST from Quokka

Q-mast is Quokka’s automated mobile application security testing solution built for teams that need deep visibility, operational speed, and strong compliance across both in-house and third-party mobile apps. Q-mast delivers in-depth security assessments to identify vulnerabilities, misconfigurations, and compliance risks—without requiring source code. Security and development teams use Q-mast to catch issues early, reduce costs tied to late-stage rework, and minimize exposure to zero-day threats.

Comprehensive coverage

Performs automated scanning in minutes, covering static, dynamic, and interactive analysis, even in obfuscated or binary-only builds — no source code needed

Seamless DevSecOps integration

Automates mobile app testing within CI/CD workflows like GitHub, GitLab, and Jenkins. Tests run in minutes, enabling continuous security without disrupting delivery

Precise SBOM analysis

Generates a complete software bill of materials (SBOM) and analysis for vulnerability reporting to specific library version, including embedded libraries

Advanced threat detection

Leverages defense-grade engines to identify malicious behavior, app collusion risks, and runtime threats

Binary-first analysis

Tests the actual compiled mobile app, not just source code, and operates reliably across all current OS versions

Compliance support

Checks against privacy & security standards and compliance regulations, including NIAP, NIST, and OWASP MASVS

Complementing MAST with Penetration Testing

Penetration testing (pen testing) involves skilled security professionals actively trying to exploit weaknesses in the app’s code, infrastructure, and logic that might go unnoticed during regular development and Q&A. While often performed just 1-3 times per year, pen testing remains a core requirement in compliance frameworks like PCI DSS, GDPR, and HIPAA, and helps reduce regulatory risk and legal exposure. Mobile Application Security Testing (MAST) and penetration testing are not mutually exclusive—they’re complementary.

How MAST and Pen Testing Work Together

MAST identifies potential vulnerabilities at scale

MAST provides a wide net, offering a comprehensive overview of the app’s security posture across multiple layers (i.e., code, application logic, network communications, and more).

Penetration testing validates exploitability and impact 

Penetration testing takes the findings of MAST and attempts to exploit them in a controlled environment, validating the actual risk and helping to prioritize remediation efforts.

Together, they deliver complete, risk-driven security

MAST covers a wide range of risks, and pen testing adds human expertise and controlled exploitation. Combined, they help teams focus on the highest security risks.
