AdaptixC2 is a modular command and control framework designed for authorized penetration testing and red team operations.
The tool addresses the need for flexible post-exploitation infrastructure by combining a Golang server backend with a cross-platform C++ Qt GUI client. Its modular architecture treats listeners and agents as plugins, allowing operators to extend functionality through custom extenders. The framework includes built-in support for multiple communication protocols including HTTP/S, DNS/DoH, SMB, and TCP beacons, along with infrastructure features like encrypted communications, credential management, target tracking, and session linking.
Teams conducting authorized security assessments should evaluate this tool if they need multiplayer server-client coordination with cross-platform GUI access across Linux, Windows, and macOS. The framework suits operations requiring flexible agent deployment across multiple operating systems and communication channels. The plugin-based extender system enables customization beyond the included HTTP/S, DNS/DoH, SMB, TCP, and Gopher listeners. An official Extension-Kit is available for building custom components.
Development activity shows ongoing refinement with documented changelog updates between versions. The project maintains a clear contribution workflow directing changes to the development branch rather than the main branch. The team provides comprehensive documentation through a dedicated wiki and gitbook resource, indicating investment in operator onboarding and framework usability.
