About Orochi

Orochi is an open source framework for collaborative forensic memory dump analysis. Using Orochi you and your collaborators can easily organize your memory dumps and analyze them all at the same time.

Fastest way to try Orochi

For people who prefer to install and try first and then read the guide:

git clone https://github.com/LDO-CERT/orochi.git
cd orochi
sudo docker-compose pull
sudo docker-compose up

Browse http://127.0.0.1:8000 and access with admin//admin

Orochi architecture

• uses Volatility 3: the world’s most widely used framework for extracting digital artifacts from volatile memory (RAM) samples.
• distributes loads among nodes using Dask
• uses Django as frontend
• uses Postgresql to save users, analysis metadata such status and errors.
• uses Mailpit to manage the users registration emails
• uses Redis for cache and websocket for notifications
• all framework is provided as docker-compose images

Getting started

Installation

Using Docker-compose you can start multiple dockers and link them together.

• Start cloning the repo and enter in the folder:

git clone https://github.com/LDO-CERT/orochi.git
cd orochi

In case you are running docker on Windows you can do wsl -d docker-desktop sysctl -w vm.max_map_count=262144 from PowerShell.

• You need to set some useful variables that docker-compose will use for configure the environment

  Here is a sample of .env\.local\.postgres:

  POSTGRES_HOST=postgres
  POSTGRES_PORT=5432
  POSTGRES_DB=orochi
  POSTGRES_USER=debug
  POSTGRES_PASSWORD=debug
  

  Here is a sample of .env\.local\.django:

  USE_DOCKER=yes
  IPYTHONDIR=/app/.ipython
  REDIS_URL=redis://redis:6379/0
  DASK_SCHEDULER_URL=tcp://scheduler:8786
  

  By default ALLOWED_HOSTS config permits access from everywhere. If needed you can change it from .envs\.local\.django

• If needed you can increase or decrease Dask workers to be started. In order to do this you have to update the docker-compose.yml file changing the number of replicas in the deploy section of worker service.

• You can pull images with command:

docker-compose pull

• Or build images with command:

docker-compose build

• Now it's time to fire up the images!

docker-compose up

• When finished - it takes a while - you can check the status of images:

docker ps -a

• Now some management commands in case you are upgrading:

   docker-compose run --rm django python manage.py makemigrations
   docker-compose run --rm django python manage.py migrate
   docker-compose run --rm django python manage.py collectstatic
  

• Sync Volatility plugins (*) in order to make them available to users:

  docker-compose run --rm django python manage.py plugins_sync
  

• Volatility Symbol Tables are available here and can be sync using this command (*):

  docker-compose run --rm django python manage.py symbols_sync
  

(*) It is also possible to run plugins_sync and symbols_sync directly from the admin page in case new plugins or new symbols are available.

• To create a normal user account, just go to Sign Up (http://127.0.0.1:8000) and fill out the form. Once you submit it, you'll see a "Verify Your E-mail Address" page. Go to your console to see a simulated email verification message. Copy the link into your browser. Now the user's email should be verified and ready to go. In development, it is often nice to be able to see emails that are being sent from your application. For that reason local SMTP server Mailpit with a web interface is available as docker container. Container mailpit will start automatically when you will run all docker containers. Please check cookiecutter-django Docker documentation for more details how to start all containers. With Mailpit running, to view messages that are sent by your application, open your browser and go to http://127.0.0.1:8025

• Other details in cookiecutter-django Docker documentation

Quick Start Guide

• register your user
• login with your user and password
• upload a memory dump and choose a name, the OS and the color: in order to speed up the upload it accepts also zipped files.
• When the upload is completed, all enabled Volatility plugins will be executed in parallel thanks to Dask. With Dask it is possible to distribute jobs among different servers.
• You can configure which plugin you want run by default through admin page.
• As the results come, they will be shown.
• Is it possible to view the results of a plugin executed on multiple dumps, for example view simultaneously processes list output of 2 different machines.
