Trapster Community

Trapster Community is a low-interaction honeypot designed to be deployed on internal networks or to capture credentials. It is built to monitor and detect suspicious activities, providing a deceptive layer to network security.

Visit the Trapster website to learn more about our commercial version, which includes advanced features like pre-configured hardened OS, automatic deployment, webhook, SIEM integration and much more...

Features

• Deceptive Security: Mimics network services to lure and detect potential intruders.
• Asynchronous Framework: Utilizes Python's asyncio for efficient, non-blocking operations.
• Configuration Management: Easily configurable through trapster.conf.
• Expandable Services: Add and configure as many services as needed with minimal effort.
• HTTP Honeypot Engine with AI capabilities: Clone any website using YAML configuration, and use AI to generate responses to some HTTP requests.

Logs

Format

Each module can generate up to 4 types of logs: connection, data, login, and query.

• connection: Indicates that a connection has been made to the module.
• data: Represents raw data that has been sent, logged in HEX format. This data is unprocessed.
• login: Captures login attempts to the module. The data field is in JSON format and contains processed information.
• query: Logs data that has been processed and does not correspond to an authentication attempt. The data field is in JSON format and contains processed information.

You can then filter log type you don't need.

HTTP Engine with AI capabilities

Configuration

The HTTP module can emulate any website. It works with YAML configuration files to match requests using regular expressions, and can generate responses using either a template or an AI model.

The configuration are stored in trapster/data/http, each folder represent a website. An example of the functionnalities can be found at trapster/data/http/demo_api/config.yaml

Structure:

• config.yaml: contains the configuration for the website.
• files/: contains the static files for the website.
• templates/: contains the templates for the website, it supports jinja2 syntax.

Example: Fortigate

The default HTTPS server shows a fortigate login page:

If someone tries to login, you will get a log like this one:

   }
}

AI ALPHA support

To generate responses, you can use the ai field in the configuration. For now, it uses OVHCloud AI Endpoints as it is still free, and in beta. The file trapster/modules/libs/ai.py contains the code to generate responses using the AI model. It is still very basic, and will be improved in the near future.

For example, this image show a request to capture SQLi attempts, and the response generated by the AI model.
