Poster: EdgeCitadel -- Hybrid NATS-MQTT Orchestration for Edge Multi-Agent Systems

This collection describes multiple edge- and distributed-AI systems that expand attack surface across brokers, telemetry, inter-device delegation, hardware-side aggregation, and cloud-edge offloading. Key risks include broker/MQTT relay misconfiguration and unauthenticated access (NATS + MQTT + JetStream), privacy and data-exfiltration when summoning cloud FMs or offloading multimodal payloads, model-poisoning and adversarial inputs in cooperative SLM/LLM swarms and RAG-driven schedulers, integrity/privacy risks from near-memory CXL-side gradient aggregation (NEURON-Fabric), and abuse or spoof
