CI StatusCoverage StatusRelease

Quick start

Dependencies

  • Docker
  • Docker Compose
  • Make

Start

  1. Configure config.yml for your competition. A detailed description of the quick configuration is here

  2. Start the farm

make up

Credentials for basic auth and the token for sending flags via start_exploit.py will be printed to stdout.

  1. After the game ends, turn off the farm and clean the database and queue
make down
make clean-all

Features

  • Uploading exploits in ui
  • Uploading exploits in cli
  • Real-time configuration farm options like number of concurrently running exploits, the size of the flag sending batch, team ip addresses, etc
  • The ability to change the plugin for sending flags to jury.
  • There are already two sending plugins: forcad_http and saarctf_tcp.
  • Different exploit types:
    • Python (one file)
    • Python (zip)
    • Bash script
    • Binary
  • View logs of running exploits and sending flags on ui
  • Configuring vulnboxes ip addresses using various methods

Components

Client

  • Frontend (./jacfarm-frontend) - ui for
    • viewing flags with any filters
    • adding exploits of different types via '+' button
    • deleting or updating exploits by right mouse button
    • adding teams
    • updating farm config
    • viewing logs

  • CLI (./cli) - tool for starting exploits on local machine

Server

  • Exploit Runner (./workers/exploit_runner) - a worker that launches exploits on all teams. More details
  • Flag Sender (./workers/flag_sender) - a worker that sends flags to jury using Plugins. More details
  • JacFARM API (./jacfarm-api) - API for frontend and cli start_exploit.py.
  • Config Loader (./workers/config_loader) - loads config into db from config.yml on start. Next configuration editing is available through the frontend.

Plugins

Plugin - is a function in a farm that sends flags to the jury system.

⚠️ Farm contains two plugins for ForcAD and saarCTF jury systems. If you write plugins for other jury systems, you can create a pull request to add them into repository.
