A device emulator is defined as a software or hardware that allows a computer system (named host) to perform as a different computer system (named guest). A device emulator generally allows the host system to use the software or peripheral devices intended for the guest system. This system allows fraudsters to repeat multiple attempts at login, signup or payment with with different parameters so they don’t get blocked, as they make it seem as if a different computer is continuing to attempt the log-ins.
