CTFd Penalty Plugin

A CTFd plugin that adds penalties for wrong challenge submissions. When a participant submits an incorrect flag, they receive a penalty that reduces their score.

Features

• Configurable penalty system for wrong flag submissions
• Two penalty types:
  • Percentage: Deducts a percentage of the challenge's value
  • Fixed: Deducts a fixed number of points
• Penalties appear as negative awards in the team/user history
• Admin interface to configure penalties
• Can be enabled/disabled without removing the plugin

Installation

1. Clone this repository into your CTFd plugins directory:

cd /path/to/CTFd/CTFd/plugins
git clone https://github.com/yourusername/ctfd-penalty.git ctfd_penalty

2. Make sure the plugin directory structure is as follows:

CTFd/plugins/ctfd_penalty/
├── README.md
├── __init__.py
├── assets/
│   └── admin/
│       ├── js/
│       │   └── penalty_settings.js

Usage

Once configured, the plugin automatically:
