Reverse Engineering an iOS App
The App Store is the official marketplace for iOS applications, and users can download the app directly from there so I decided to start from there App Store (https://apps.apple.com/it/app/la-mia-banca/id589025584) however the application is encrypted so I decided to use the CrackerXI tool to decrypt the app, and export the binary file to my local machine. After disassembling the binary with Hopper, I discovered that the application uses an opensource framework to prevent tampering
As an open-source framework with no obfuscation, it is extremely easy to bypass this system. I just created a script for Frida to bypass this protection; for security reasons, I will not share the script.
