This Flask application is designed to detect Capture The Flag (CTF) flags from input data using GPT-4. The app queries the GPT-4 model with provided information, checks if the response contains a CTF flag, and sends an alert if a flag is detected. This project leverages OpenAI's GPT-4 model to assist in CTF competitions by detecting flags from provided input data. The app is designed to streamline the process of flag detection by automating the query and response analysis using advanced AI models.
- Accepts input data and queries GPT-4.
- Detects CTF flags within the GPT-4 response.
- Sends alerts when a CTF flag is detected.
Ensure you have the following installed:
- Python 3.7+
- Flask
- OpenAI Python Client
- OpenAI tokens
All required Python packages are listed in the requirements.txt file.
-
Clone the repository:
git clone https://github.com/yourusername/ctf-flag-detector.git cd ctf-flag-detector -
Set up a virtual environment (optional but recommended):
python3 -m venv venv source venv/bin/activate -
Install the required packages:
pip install -r requirements.txt
-
Set up the environment variable:
The application requires an OpenAI API key to function. Set it as an environment variable:
export OPENAI_API_KEY='your-openai-api-key-here'
Alternatively, you can create a
.envfile in the root of the project and add your API key there:OPENAI_API_KEY=your-openai-api-key-here
-
Run the Flask app:
flask run
-
Send a POST request with the necessary information:
The Flask app will listen for incoming data and query GPT-4 to check for CTF flags. If a flag is detected, an alert will be sent.
Example cURL request:
curl -X POST http://127.0.0.1:5000/detect -d "input_data=your_input_here" -
Monitor the output:
The app will return a response indicating whether a CTF flag was detected.
