Resigning the IPA file would allow installation of the mobile app. Altering the IPA will break the signed application and it won’t be installed on any iOS device. It will point you in the direction of where the iOS certificate pinning is happening. Once binary is loaded in the application, you can follow the logic behind the functions which are called when the mobile app makes an SSL connection with the server. Hopper and IDA are the two famous disassemblers that you can use for this task. If everything fails, you will have to try something difficult - use disassemblers to modify the IPA file for bypassing a certificate validation.

Using disassemblers for modifying the IPA file Their individual installation instructions have been listed on their websites. The easiest way for bypassing SSL certificate pinning would be to install hardwares, which are easy to setup and run. If you still get the SSL errors or if the app dies after waiting for a connection, the probability is the server is using a TLS chain validation or SSL certificate pinning. On a default mode, the SSL implementations used in the apps trust any server having certificates trusted by an operating system’s trust store. When a mobile app communicates with a server, it uses SSL for protecting the transmitted data against tampering and eavesdropping. This would help your QA team know the routes they have to focus on when ensuring your iOS application security.īefore we move on with giving you the SSL pinning technique bypass ways to bypass SSL Pinning in iOS, let me bring everyone on the same platform by describing what it is. The intent of this article is to look into the different ways of how SSL certificate pinning in iOS can be bypassed. What is even worse is that it is active in one of the most secure ecosystems of the mobile domain - iOS as well. One breach that has become frequently occuring in the mobile domain is the SSL Pinning bypass. Scarily, the instances and types of security breaches are growing alongside the number of apps active in the stores. The stage alone holds the capability to make or break the future and success of an app empire. Mobile app security has always been one of the most crucial parts of the entire design and development process.
