What is the OWASP MASTG?
The OWASP Mobile Application Security Testing Guide (MASTG) is the go-to open-source handbook for professionals working in mobile security. Backed by the trusted OWASP Foundation, the MASTG offers a comprehensive, practical guide to mobile app security testing and reverse engineering across both iOS and Android platforms. It aligns closely with the Mobile Application Security Verification Standard (MASVS), forming a powerful duo for ensuring mobile apps are secure by design.
Why MASTG Matters
With mobile apps becoming a dominant force in digital interaction, their security is critical. The MASTG provides the technical depth and real-world techniques security testers and developers need to identify vulnerabilities, implement effective defenses, and ensure compliance with industry standards.
Key Use Cases:
- Mobile application penetration testing
- Security audits and compliance verification
- Training for ethical hackers and developers
- Reverse engineering for vulnerability research
How to Get Started
Getting started with the MASTG is easy. You can:
- Download the latest PDF version
- Access mobile app security checklists
- Try hands-on challenges via Crackmes
- Get involved by contributing to the project
Prefer printed or e-book formats? You can find them on lulu.com and Leanpub.
Core Features
The MASTG provides detailed, platform-specific security testing techniques, including:
- Static and dynamic analysis
- Reverse engineering tools and workflows
- Testing cryptographic implementations
- Securing local storage and authentication flows
- Testing inter-app communication
- Network traffic inspection and interception
Each test case is mapped to MASVS requirements, making the guide highly structured and actionable.
Trusted Across the Industry
MASTG and MASVS are trusted by platform providers, standardization bodies, governments, and educational institutions worldwide. Their wide adoption ensures that you’re learning and applying up-to-date, relevant security practices recognized across industries.
Security and Ethical Use
As with all OWASP tools and resources, the MASTG is intended for ethical and legal use only. Its content supports defenders, auditors, researchers, and developers in improving mobile app security-not exploiting it.
