MQTT Privacy & Exposure Analysis

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

Exposure Level: Broadcast
Privacy Features:
  • βœ“ Direct LoRa transmission (not via MQTT)
  • βœ“ Gateway node ID tracked
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Default channel - no encryption
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ Multi-hop path visible (1 hops)
  • ⚠ RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
