Introduction

The Packing Box is a Docker image containing various tools for studying executable packing. It is designed to instrumentalize packers and packing detectors and to create datasets for comparing packing detection techniques.

It aims to provide a single platform for studying packing for more than what we can traditionally see in the literature, that is essentially techniques applied to Windows PE files in the scope of malware analysis. From the Packing Box (based on Ubuntu, therefore supporting the ELF format), Wine is used to handle PE files. Ultimately, it aims to also handle the Mach-O format (using Darling).

Setup

Setting up the Packing Box requires installing Docker and cloning this repository. The Dockerfile can then be used to build the image.

# apt install docker
[...]
# git clone https://github.com/packing-box/docker-packing-box
[...]
# docker build -t packing-box .
[...]

Run

Running the Packing Box is done by starting it up with Docker.

# docker run -it -h packing-box -v `pwd`:/mnt/share packing-box

  This Docker image is a ready-to-use platform for making datasets of packed and not packed executables, especially for training machine learning models.

From inside the box, help can be obtained by using the "?" tool. This will display the welcome message seen when starting it. It has a few useful options ;

  • -f FORMAT / --format FORMAT: allows to filter out items based on the input executable format

  • -i ITEM / --item ITEM: allows to see the particular help of an item from the box

# ? -i peid

PEiD detects most common packers, cryptors and compilers for PE files.

  • -k {detectors,packers,unpackers} / --keep {detectors,packers,unpackers}: allows to filter out items of a single kind

  • --show-all: will make the tool display the whole items, even those that are marked as broken.
