Objective-C : Insufficient jailbreak detection

The application uses a well-known method of testing for the presence of OS superuser rights (jailbreak). An attacker who has privileged access can bypass the check.

The application that works with valuable data must check the device for jailbreak and limit the functionality in case of a positive result. Some test procedures are published and, most likely, are known to the attacker, who as a result can bypass them. It is recommended to use a non-trivial tests for jailbreak.

Theoretically, having a root, an attacker can bypass any checks for jailbreak. But the more different non-trivial tests are used, the lower the probability of such an event.
