Docker Images of Malware Analysis Tools
The REMnux toolkit provides Docker images of popular malware analysis tools that you can run on any compatible system even without installing the REMnux distro. These images reside in the REMnux repository on Docker Hub, and are based on the files maintained in the REMnux Github repository.
In addition to the Docker images of individual tools, described below, you can run the REMnux distro inside a pre-built Docker container.
Docker is installed as part of the REMnux distro. If you're planning to run REMnux Docker images on another system, you may need to install Docker. The first time you run an image (e.g., using the docker run command), Docker will automatically download the image from Docker Hub, run it locally as an active container. Your system will need to be connected to the internet to retrieve the image; afterwards, Docker will use a locally cached copy. You can use the docker pull command to update the cached version of the image. To update all local images from a Linux-like shell, run:
The following Docker images of malware analysis tools are available as part of REMnux. If you have the expertise, consider adding to this collection by contributing a Dockerfile to the REMnux toolkit.
Thug Low-Interaction Honeyclient
Thug is a low-interaction honeyclient for examining suspicious websites. This tool was created by Angelo Dell'Aera. It's licensed under GNU General Public License (GPL) v2. In addition to being available as a Docker image, Thug is also installed as part of the REMnux distro.
One way to run Thug as a Docker image is to invoke it using the following command to open a shel in the container where you can run thug with the desired parameters, such as -F to enable file logging).
The password for the container's user thug is thug. The remnux/thug image is hosted on its Docker Hub page.
Binary Refinery
The Binary Refinery™ is a collection of Python scripts that implement transformations of binary data such as compression and encryption. You can chain the tools as necessary to achieve your objective. This toolkit is authored by Jesko Hüttenhain and licensed under the 3-Clause BSD License.
To run Binary Refinery tools within the "remnux/binary-refinery" container, create a directory where you'll store your input files, e.g. ~/workdir. Then, use a command like this to launch the container and have your directory mapped as /home/nonroot/workdir inside the container:
The binary-refinery Docker image is hosted in the REMnux Docker Hub repository.
For documentation about this toolkit, including the listing of its tools, see https://binref.github.io and https://github.com/binref/refinery.

To stop JSDetox, use the command docker stop jsdetox. The remnux/jsdetox image is hosted on its Docker Hub page.
de4js JavaScript Deobfuscator and Unpacker
de4js is a browser-based tool for deobfuscating and unpacking JavaScript. It was created by Zzbaivong and is licensed under MIT License. If you don't want to run de4js locally using the Docker image outlined below, you can use the version hosted on its author's website.
You can use the following command to launch the de4js Docker image, with the application listening locally on TCP port 4000. You can then connect to http://localhost:4000/de4js/ using your web browser:
It's important to remember the trailing slash as part of the de4js URL http://localhost:4000/de4js/.
To stop de4js, use the command docker stop de4js. The remnux/de4js image is hosted on its Docker Hub page.

The password for the container's user retdec is retdec. The remnux/retdec image is hosted on its its Docker Hub page.
The commands provided by RetDec include start with the retdec- prefix and include retdec-decompiler.py, retdec-unpacker, and retdec-fileinfo.
Rizin Reverse-Engineering Framework
Rizin is a reverse-engineering framework that includes a disassembler and analysis capabilities for a variety of executable formats and architectures. It's licensed under GNU Lesser General Public License (LGPL) v3. This is a fork of the Radare2 project.
To run Rizin, create a directory where you'll store the files you plan to examine. Then, open a shell inside the container where you can run Rizin commands (rizin and others that start with rz-) and have your local directory mapped as /home/nonroot/workdir inside the container:
If you're planning to peform kernel-mode debugging, process tracing, or syscall tracing inside the container, then supply the parameters --cap-drop=ALL --cap-add=SYS_PTRACE when launching it.
The password for the container's user nonroot is nonroot. The remnux/rizin image is hosted on its its Docker Hub page.
