When this API is called, SafetyNet will download a package containing device validation code which is provided by Google. However, we have included reference links to the documentation. How exactly SafetyNet works is not well documented. SafetyNet is an Android API that creates profiles of devices according to software and hardware information and then compares it to a list of whitelisted device models, which have cleared Android compatibility testing. Google SafetyNet Attestation API – ctsProfile and basicIntegrity Reference ImplementationĪndroid Anti-Emulator is one such GitHub repo that uses various ways of detecting an emulated Android environment and determines if the application is running on a virtual device or not. Having emulator detection gives one layer of additional projection to your application against runtime manipulation. Many security researchers and penetration testers use virtual devices for testing the security of Android applications. Implement Google SafetyNet Attestation API – ctsProfile and basicIntegrity.If any of the checks (from Step 1 to Step 5) fails, then don’t allow the end-user to continue further. In the following section, we have listed common root detection methods as well as reference steps for implementation.

Detecting rooted devices alone are not sufficient, but implementing various checks scattered throughout the app can improve the effectiveness of overall implementation and improve the security of Android apps. The goal of comprehensive root detection is to make running the application on a rooted device more difficult.

Hence, there is a strong need of making root detection checks more comprehensive. This way, it is easier to bypass root checks. In this method, modifications are stored in the boot partition instead of modifying OS files. One such method is the “systemless” root. With time, security researchers have found newer and better ways of rooting Android devices which makes root detection harder. Earlier, installing Chainfire’s SuperSU was one of the common ways of rooting Android devices.
