Assemblyline incident manager

This repository contains three Python scripts used for bulk triaging file using Assemblyline.

  1. Submitter (al-incident-submitter): pushes files from a directory to an Assemblyline instance for analysis.
  2. Result analyzer (al-incident-analyzer): pulls the submissions from the Assemblyline instance and reports on if the submissions are safe/unsafe.
  3. Downloader (al-incident-downloader): downloads files submitted to Assemblyline that are under a certain score threshold, matching the folder structure of the files as they were submitted.

Prequisites

  • You will need the URL of an Assemblyline instance that you have an account on, for best results make its loaded with your best Yara rules, Sandboxes etc.
    • Want to create your own Assemblyline instance? HOW-TO
  • You will need two API keys generated by Assemblyline, ideally one with read access and another with write access.
    • The Write-only key will be used for the "Submitter" and the Read-only key will be used for the "Result Analysis" and the "Downloader".
    • This helps in the context of incident response to reduce the exposure of your Assemblyline instance.

Installation

Linux

  • Install the following packages: libffi-dev, libssl-dev
    • (APT) sudo apt-get install libffi-dev libssl-dev python3
    • (YUM) sudo yum install libffi-dev libssl-dev python3
  • Upgrade PIP: python3 -m pip install --upgrade pip
  • python3 -m pip install assemblyline-incident-manager

Windows

  • Download and install the most recent Python .msi installer from https://www.python.org/downloads/release.

L'assistant à la réponse aux incidents d'Assemblyline

Ce répertoire contient trois scripts Python pour assisté le triage de grande quantité de fichiers avec Assemblyline.

  1. Soumission (al-incident-submitter): envoi les fichiers contenu dans un dossier vers une instance Assemblyline pour l'analyze.
  2. Résultats d'analyse (al-incident-analyzer): analyse les soumissions et génère un rapport.
  3. Téléchargeur (al-incident-downloader): télécharge les fichiers sous un certain pointage en préservant la structure original.

Prérequis

  • Vous aurez besoin d'un instance d'Assemblyline à jour et avec vos meilleurs règles Yara, "Sandboxes" etc.
    • Voici comment crée vôtre propre instance: LIEN
  • Nous vous recommandons d'utilisé deux clé d'api, un write only et une read only
    • La clé Write-only sera utilisé pour soumettre vos fichier avec le script "Submitter" et la clé Read-only sera pour "Result Analysis" et le "Downloader".
    • Cette séparation aidera a securisé vôtre instance Assemblyline dans un context de réponse aux incidents
