 ## About the OWASP Mobile Security Testing Guide
 
-The OWASP Mobile Security Testing Guide (MSTG) is a comprehensive manual for testing the security of mobile apps. It describes processes and techniques for verifying the requirements listed in the [Mobile Application Security Verification Standard (MASVS)](https://github.com/OWASP/owasp-masvs "MASVS"), and provides a baseline for complete and consistent security tests.

 # Mobile App Authentication Architectures
 
-Authentication and authorization problems are prevalent security vulnerabilities. In fact, they consistently rank second highest in the [OWASP Top 10](https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project "OWASP Top Ten Project").
+Authentication and authorization problems are prevalent security vulnerabilities. In fact, they consistently rank second highest in the [OWASP Top 10](https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project).
 
 Most mobile apps implement some kind of user authentication. Even though part of the authentication and state management logic is performed by the backend service, authentication is such an integral part of most mobile app architectures that understanding its common implementations is important.

 Another real-world instance of client-side SQL injection was discovered by Mark Woods within the "Qnotes" and "Qget" Android apps running on QNAP NAS storage appliances. These apps exported content providers vulnerable to SQL injection, allowing an attacker to retrieve the credentials for the NAS device. A detailed description of this issue can be found on the [Nettitude Blog](https://blog.nettitude.com/uk/qnap-android-dont-provide "Nettitude Blog - QNAP Android: Don\'t Over Provide").
