Planting C4: Cross-Compatible External C2 for Your Implants

Scott Taylor

Scott Taylor introduces C4, an open-source framework decoupling payload implants from command-and-control protocols using versatile external connectors.

Summary

Architectural Bottlenecks in Modern C2 Frameworks

Scott Taylor analyzes the limitations of traditional red team implants that tightly couple execution logic to specific transport protocols, making evasion adaptation difficult during active operations.

Introducing the C4 Modular Connector Architecture

The talk introduces C4, an extensible open-source framework that separates implant execution from transport layers, enabling live protocol swapping across arbitrary channels (DNS, WebSockets, cloud storage, or social media).

Practical Demonstrations and Operator Integration

Taylor demonstrates deploying cross-platform implants with custom connectors and provides guidance on integrating C4 with existing offensive toolsets and testing defensive resilience.
