The lower level emulator objects can also be used, however their interfaces may change in the future and may lack documentation.īelow is a quick example of how to emulate a Windows DLL: import speakeasy # Get a speakeasy object se = speakeasy. The main public interface named Speakeasy should be used when interacting with the framework. Speakeasy can be imported and used as a general purpose Windows emulation library. Run the Docker image and create a local volume in /sandbox:ĭocker run -v :/sandbox -it "my_tag" Usage.Build the Docker image the following commands will create a container with the tag named "my_tag":.The included Dockerfile can be used to generate a docker image.

The easiest method of installation is by first installing the required package dependencies, and then running the included setup.py script (replace "python3" with your current Python3 interpreter): cd python3 -m pip install -r requirements.txt python3 setup.py installĪ docker file is also included in order to build a docker image, however, Speakeasy's dependencies can be installed on the local system and run from Python directly. Speakeasy can be executed in a docker container, as a stand-alone script, or in cloud services. These APIs and their structure should be consistent with the API documentation provided by Microsoft.

The CPU emulation engine can be swapped out and there are plans to support other engines in the future.ĪPIs are emulated in Python code in order to handle their expected inputs and outputs in order to keep malware on their "happy path". Speakeasy is currently written entirely in Python 3 and relies on the Unicorn emulation engine in order to emulate CPU instructions. Events are logged on a per-entry-point basis so that functionality can be attributed to specific functions or exports. The goal here is to have as much code coverage as possible during emulation. new threads, registered callbacks, IRP handlers) that are discovered at runtime are also emulated. For example, exported functions are all identified and emulated sequentially. Currently, Speakeasy supports both user mode and kernel mode Windows applications.īefore emulating, entry points are identified within the binary. Samples can be easily emulated in a container or in cloud services which allow for great scalability of many samples to be simultaneously analyzed. Specifically, by emulating operating system APIs, objects, running processes/threads, filesystems, and networks it should be possible to present an environment where samples can fully "execute". Instead of attempting to perform dynamic analysis using an entire virtualized operating system, Speakeasy will emulate specific components of Windows. Speakeasy is a portable, modular, binary emulator designed to emulate Windows kernel and user mode malware.Ĭheck out the overview in the first Speakeasy blog post.
