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)
  • ✓ Targeted to specific node
  • ✓ Gateway node ID tracked
Exposure Risks:
  • ⚠ Default channel - no encryption
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ Multi-hop path visible (7 hops)
  • ⚠ RF signal metrics exposed (location inference possible)
