Introduction

This tool automates the research of some artifacts for forensics purpose in memory dumps based upon Volatility for a series of common Windows applications. It is aimed to facilitate triage while addressing multiple forensics images.

It can also open multiple archive formats. In case of an archive, the tool will extract all its files to a temporary directory and then try to open each file as a memory dump (except files named README or README.md).

System Requirements

This framework was tested on an Ubuntu 18.04 with Python 2.7. It relies on Foremost and Volatility

$ sudo apt-get install foremost
$ git clone https://github.com/volatilityfoundation/volatility /tmp/vol-setup
$ cd /tmp/vol-setup && sudo python setup.py install

Setup

$ pip install appmemdumper

Behind a proxy ?

Do not forget to add option --proxy=http://[user]:[pwd]@[host]:[port] to your pip command.

This tool automates the research of some artifacts for forensics purpose in memory dumps based upon Volatility for a
series of common Windows applications.

It can also open multiple archive formats (it uses pyunpack). In case of an archive, the tool will extract all its files
to a temporary directory and then try to open each file as a memory dump.
