Root and Jailbreak Detection

Mobile app checks that determine whether a device has been rooted (Android) or jailbroken (iOS), indicating weakened platform security.

Definition

Apps such as banking or DRM clients may restrict functionality on compromised devices. Detection can be bypassed by determined attackers, so it should be one layer of resilience combined with server-side attestation.

Example

A payment app disables tap-to-pay when it detects a rooted device.

Exam tip

Detection raises cost but is bypassable; pair it with attestation.
