MQTT Privacy & Exposure Analysis

Analysis of privacy features and exposure risks when packet is shared via MQTT

Exposure Level: Direct Message
Privacy Features:
  • ✓ Direct LoRa transmission (not via MQTT)
  • ✓ Acknowledgment requested
  • ✓ Targeted to specific node
  • ✓ Custom channel: MediumFast
  • ✓ Gateway node ID tracked
Exposure Risks:
  • âš  Packet visible to MQTT subscribers
  • âš  Multi-hop path visible (1 hops)
  • âš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
