But it still has artifacts that betray its presence. Therefore, several proprietary checks have to be done by the RASP system.Īn emulator reproduces, with great fidelity, the behavior and functioning of the original operating system.

There is no official API in iOS or Android to detect an emulator. A simulator acts more as a ‘stub’ system that mimics rather than emulate (hence the name).
A hypervisor can be seen as “in-between” a virtual machine and an emulator. A virtual machine relies on a real CPU to perform virtualization. An emulator, ‘emulates’ the whole system, including the processor, in software (which means that it is often very slow). There are differences between an emulator, a virtual machine, a hypervisor, and a simulator. This article mainly looks at a number of techniques for detecting Android emulators.Īs we shall see, there are many ways to detect emulators, but there are also a great number of such emulators on the market and counting! Android and iOS Emulators Often-used Android emulators include: In order to prevent a mobile app from running on an emulator, effective emulator detection must first be in place.
Whatever an attacker wants to do: reverse the code, attach a debugger, tamper the application, etc., the first step is usually to use an Android or iOS emulator.Īn important role of Runtime Application Self-Protection (RASP) mechanisms is, therefore, to prevent the protected application from running inside an emulator (simulated environment). Attacks against mobile banking & payment applications often start by using an emulator for the mobile operating system where the targeted application will be run and analyzed.
