MQTT Privacy & Exposure Analysis

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

Exposure Level: Broadcast
Privacy Features:
  • โœ“ Direct LoRa transmission (not via MQTT)
  • โœ“ Gateway node ID tracked
Exposure Risks:
  • โš  Visible to all nodes on channel
  • โš  Default channel - no encryption
  • โš  Packet visible to MQTT subscribers
  • โš  Multi-hop path visible (3 hops)
  • โš  RF signal metrics exposed (location inference possible)
