Have you ever wanted to just run that damn code you are looking at in IDA Pro? You are not alone. Even assuming you can find a working emulator for the required processor, execution requires setting up enough of a complete initial runtime environment and that is by no means easy. There are many puzzle pieces to assemble and put in the right places including register and memory contents, operating system information, libraries, and peripheral models. SmallWorld is designed to make all of that easy, in addition to supporting popular dynamic analysis platforms like Unicorn, angr and others for dynamic analysis. You can even readily move machine state between such platforms. In short, SmallWorld makes code harnessing and dynamic analysis fast and easy. We will explain all of this in detail and present three demonstrations of common but juicy use cases.
