Beelzebub Description
Beelzebub is an open-source deception runtime framework written in Go that deploys adaptive decoy services across multiple protocols to engage attackers and collect threat intelligence. The framework uses large language model (LLM) integration to generate contextually accurate responses in real time, keeping attackers engaged long enough to collect actionable tactics, techniques, and procedures (TTPs). It supports SSH, HTTP, TCP, TELNET, and MCP (Model Context Protocol) deception services, covering both traditional infrastructure attack surfaces and AI agent attack surfaces. Key capabilities: - Adaptive deception engine powered by LLMs (OpenAI, Ollama) that generates realistic responses to attacker inputs - Low-code service definition using YAML configuration files with regex-based command matching - Multi-protocol decoy services: SSH, HTTP, TCP, TELNET, and MCP - Detection of prompt injection attacks targeting AI agents via MCP deception services - Extensible plugin system using CommandPlugin and HTTPPlugin interfaces registered via init() - Full observability through Prometheus metrics and RabbitMQ event streaming - Production deployment support via Docker, Docker Compose, and Kubernetes (Helm) - Per-service memory limits and graceful shutdown support - CLI tooling including service validation for use in CI pipelines The framework is configured entirely through YAML files, requiring no custom code to deploy new decoy services. It is listed in the Awesome Go repository and is available under an open-source license on GitHub.
