## What is CobaltBus?

CobaltBus is a tool that integrates Cobalt Strike with Azure Service Bus to create covert command and control (C2) communication channels.

The tool leverages Azure Service Bus infrastructure to facilitate C2 traffic routing, allowing red team operators to establish communication with compromised systems through Microsoft's cloud messaging service.

By utilizing Azure Service Bus as a communication medium, CobaltBus enables red teams to blend C2 traffic with legitimate cloud service communications, potentially evading network detection mechanisms that monitor traditional C2 protocols.

The integration allows Cobalt Strike beacons to communicate through Azure Service Bus queues and topics, providing an alternative C2 channel that appears as normal Azure cloud traffic to network monitoring systems.
