Repo containing docker-compose files and setup scripts without having to clone the individual reternal components

RE:TERNAL

---

---

Note: Still under development, only use for testing and do not expose interfaces! Current compose doesn't work yet, only try when you know what you're doing

RE:TERNAL is a centralised purple team orchestration service to manage third-party C2 frameworks. Agents are installed on endpoints to to execute various known red-teaming techniques in order to test blue-teaming capabilities. The simulations are mapped to the MITRE ATT&CK framework. This repo contains the compose file in order to set up the reternal platform via docker.

There is a public preview available running the latest version @ https://reternal.d3vzer0.com (Github login required). Executing/saving campaigns and interacting with the C2 modules is disabled (for obvious reasons ;)).

Reternal components

Component	Description	Code	Build
API	Administrative API to schedule tasks
UI	VueJS-based UI buildscript and NGinx webserver
C2	Distributed tasks to interact with external C2 frameworks
Search	Distributed tasks to execute search queries (ie. Splunk/Elasticsearch) for ATT&CK coverage rating
Mitre	Repository containing already existing mapped techniques for reternal

Component	Description	Build
Total Stack	Build verifying entire stack via docker-compose in this repository	TODO

Install and Configuration

This repository contains Ansible deployment playbooks to automate the local or remote installation and configuration for Reternal. The guide can be found on the repo's Wiki @ https://github.com/d3vzer0/reternal-quickstart/wiki.

Whats up with the name?

This project has been re-developed so many times, it will probably never really finish. Hence RE (Redo) and Ternal (Eternal).

Special Thanks

• Rabobank DeTTECT - Framework for mapping your log coverage against MITRE ATT&CK. Used the fundementals for the internal coverage rating and scenario suggestions: https://github.com/rabobank-cdc/DeTTECT
• MITRE ATT&CK - Framework used for mapping simulations: https://attack.mitre.org/wiki/Main_Page

• https://www.splunksecurityessentials.com/ - Must have Splunk app to extend your current detection capabilities. The app analyses the available sourcetypes and provices suitable tips/tricks to improve the overal use of Splunk for Hunting and Detection.

Examples and screenshots

All of the features will be documented on the Welcome page of the Wiki @ https://github.com/d3vzer0/reternal-quickstart/wiki. Below are a few examples of the main components.

Actor / Technique mapping

Reternal automatically maps available commands and techniques to actors. You can directly add all the techniques commonly used by actors to your set of tasks.

Recipe / Graph builder

Scheduling tasks to be run on an agent is called a graph. You can add manual commands to a graph or select one of the existing mapped techniques or actor TTPs. You can drag/drop to change the order of the tasks in your graph.

C2 interaction

Reternal acts as a piece of middleware and interacts with external C2 frameworks. An example is shown below how Reternal manages external listeners and generates stagers.

Coverage rating (based on Rabo DeTTECT)

Automatically synchronise the available datasources with your Splunk environment or add logsources manually. Reternal will suggest specific campaigns to execute based on your coverage rating.

With an overview of your coverage compared to all the ATT&CK techniques:

Integrated Hunts

Additionally a list of Splunk queries are included to automatically validate simulations. Soon (tm) the scheduled campaign will automatically run relevant queries and present a detailed report containing the findings (ie. time when attack was performed vs. time of detection etc)

Campaign state and dashboard

The main dashboard displays the state of your running campaigns and displays the expected coverage of your datasources vs techniques

reternal-quickstart's Issues

Linux 64bit ELF agent bug

Consider creating an installation Guide not using Docker

Dear Sirs,

I t would be great to have a configuration guide that used a standalone server.

Happy to try and help out. Would the starting point be:-
Mongo db
Redis
Python 3.6
Python dependencies
Webserver for flask app and vue.js

Cheers

Agent errors (interface is nil)

agents errors on windows10x64 and windows7x64 OSs is same:

Payloads failing to build

I've built RE:Ternal via manual docker method and set it up. It appears to be working except for when it comes to building the payload to install on endpoints. There are no console errors in the browser but I get the below when checking the status.

Missing Command in install instructions? Can't run ansible playbook

Is there an install command missing from this section at this link>
https://github.com/d3vzer0/reternal-quickstart/wiki/2.-Install---Configuration-Guide

4. Running the Reternal Playbook
   The standalone.yml file is a role definition file that states what components should be configured/installed on your infrastructure. The role uses the secrets in the previously created vault file to secure the Reternal components. To run the deployment role, execute the following command and specify your vault and your sudo/su password:
   If you want to deploy on localhost in dev mode (only listens on localhost + debug mode):

SEEMS LIKE THERE WAS A COMMAND HERE<<
Running reternal locally for development does not require any changes to the existing config. If you have docker installed, simply run the below command to get the environment running:

ansible-playbook reternal.yml -i inventories/standalone/dev/hosts.ini --ask-vault-pass

As a result, I am trying to use development mode instead and am getting the following error message when attempting to run this command:

ansible-playbook reternal.yml -i inventories/standalone/dev/hosts.ini --ask-vault-pass

//Message:

that the implicit localhost does not match 'all'

ERROR! playbooks must be a list of plays

The error appears to have been in '/home/pat/reternal-quickstart/ansible/inventories/standalone/dev/group_vars/reternal.yml': line 13, column 1, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

Yeh,

This look Awesome!!!! Can't wait to have it release!!!

Docker reternal-c2 not running

Hi,
I would like to understand why docker reternal-c2 stop running.
What's wrong with redis ?

There is a copy of command docker logs reternal-c2, then it's a copy of docker logs reternal-socketio.

Moreover, when I restart all containers, reternal-proxy crash .. don't know why...

Thank you !
