Havoc is a post-exploitation command and control framework designed for red team operations and penetration testing activities. The framework implements a client-server architecture that includes a cross-platform user interface, teamserver component, and demon agent for target systems. It provides payload generation capabilities for creating custom implants and supports malleable C2 profiles that allow operators to customize communication patterns and behaviors. The system offers extensibility through external C2 integrations and supports the development of custom agents for specialized requirements. Havoc runs on multiple Linux distributions including Debian, Ubuntu, and Kali Linux, requiring Qt framework and Python 3.10.x for operation. The framework facilitates team collaboration through its multi-user teamserver architecture, enabling multiple operators to coordinate activities during engagements. It includes features for managing compromised systems, executing commands, and maintaining persistent access to target environments. As an actively developed project, Havoc continues to evolve with potential breaking changes to APIs and core structures as it progresses toward maturity.
