There is an organization called OWASP that has a series of guidelines, one of which concerns itself with mobile app security. When I worked for a fintech startup, audits were executed based on this guideline, so maybe it's worth taking a look at it: https://github.com/OWASP/owasp-masvs

OWASP MASVS, MSTG, and WSTG.

Security falls under the category non-functional requirements. It should define the needed security functionality the software has to satisfy. To save up time and not re-invent the wheel on each new project, you can select security requirements from a catalog. There is a general one called "Application Security Verification Standard (ASVS)" and one for the mobile named "Mobile Application Verification Standard (MASVS)". They contain a collection of requirements which are best practices for each listed category. Fortunately they have mapped those requirements with CWE (common weakness enumeration which is basically a list of software and hardware weaknesses). Depending on the used tools, those CWEs can be automatically scanned in your code.

The project team of the OWASP Mobile Application Security Verification Standard (https://github.com/OWASP/owasp-masvs) is right in the middle of completely refactoring the document and it's requirements for mobile apps! We were re-visiting this topic in the last few months and tried to identify the current pain points and how they could be removed.

In order to move forward we are looking for your feedback! If you would like to share any feedback or comments of what should be changed in the MASVS, please do so by participating in our Github Discussion:

I've only been able to scan through the MASVS L2 standard info which you sent. I'll review it more later.

> The OWASP Mobile Application Security (MAS) flagship project provides a security standard for mobile apps (OWASP MASVS) and a comprehensive testing guide (OWASP MASTG) that covers the processes, techniques, and tools used during a mobile app security test, as well as an exhaustive set of test cases

Have a look at the OWASP Mobile Application Testing Guide https://github.com/OWASP/owasp-mastg

Be aware that this kind of tools shouldn't be seen as a substitute for a manual and thorough pentesting of the application. As u/StoryOfDavid suggested decompiling the application (I usually use jadx for this) and using Wireshark to check the network traffic are good ways to start assessing the security of your application. If you want to be thorough I suggest going through the OWASP-MSTG guide (now renamed to MASTG) which provides a categorization of possible security issues, with a description of the problem and actionable ways to statically/dynamically analyze your application.

Check out OWASP, they have plenty documentation about threat modeling and attack vectors for mobile apps. Regarding jailbreak detection, see the following: https://github.com/OWASP/owasp-mstg/blob/master/Document/0x06j-Testing-Resiliency-Against-Reverse-Engineering.md
