Overview

OvisBot is a modular, feature-extensive Discord bot for managing CTF teams through discord. It facilitates collaboration and organisation by providing well defined commands to create/delete/update discord category/channels in order to structure CTF problems and provide more efficient team commmunication. In addition the bot provides basic utility functions to assist the solving process of CTF challenges (encoding schemes, etc.. ). Finally, promotes competitiveness amongst team members by providing a aut-synchronised leaderboard to common cybersecurity training platforms such as CryptoHack and Hack The Box,

Note that the majority of the features are provided by isolated plugins and thus they can be enabled/disabled on demand.

This is a self-hosted bot, therefore it requires to be hosted on a private server in order to be used. Further instructions to do so are provided below. It also required a running instance of MongoDB on the server but still, the docker-based installation instructions take care of that.

Installation

There are couple ways to install the bot but generally the installing using docker-compose is the most convenient way to do it. Nevertheless, don't hesitate to use any other methods that suits you.

Installing using pip

To install using pip run the following command

pip install ovisbot

The above will install ovisbot in your python environment and will introduce the ovisbot cli. The cli provides commands to launch and interact with ovisbot.

At runtime, the bot requires a running MongoDB server. An easy way to run a local mongodb server is using docker. You skip this step if you already have one running

docker run -d -p 27017-27019:27017-27019 --name mongodb mongo

Since OvisBot requires some predifined configuration before launch, it is necessary the you set your environment variables accordingly. Alternatively you can create a .env file that defined the required variables. Refer to .env.example for an example.

OvisBot cli provides the setupenv command which assists the creation of a .env file. Therefore to contrinue run and fill in the variables.

ovisbot setupenv

At the end of the process a new .env file will be create in your current directory.

Finally to launch the bot, run:

ovisbot run

Installing using docker

Installation using docker takes care of running mongo db automatically without requiring any extra steps. To achieve this, docker-compose is utilised therefore make sure that you have docker and docker-compose installed on your system.

Firstly clone this repository:

git clone https://github.com/cybermouflons/ovisbot ovisbot && ovisbot

For the next step make sure that you have your environment variables configured properly and run:

docker-compose -f docker-compose.yml -f docker-compose.prod.yml up
