Foojank

Foojank is a prototype command-and-control (C2) framework that uses NATS for C2 communications.

NATS is a widely used message broker in IoT and cloud systems to facilitate communication between geographically distributed services. NATS allows passing messages between connected services and offers a persistence layer known as JetStream, enabling it to store messages on the server even when the receiver is offline. Additionally, NATS provides an object store that can be utilized for storing files.

Foojank leverages the NATS features to offer:

• Asynchronous or real-time communication with Agents over TCP or WebSockets.
• Server-based storage for file sharing and data exfiltration.
• JWT-based authentication and authorization.
• Full observability.
• Extensibility.

Foojank is currently compatible only with our prototype agent, Vessel. However, we plan to implement support for integrating custom agents into the framework in the future.
