MQTT Privacy & Exposure Analysis

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

Exposure Level: Broadcast
Privacy Features:
  • ✓ Direct LoRa transmission (not via MQTT)
  • ✓ Gateway node ID tracked
  • ✓ Zero-hop: direct from source to MQTT gateway
Exposure Risks:
  • âš  Visible to all nodes on channel
  • âš  Default channel - no encryption
  • âš  Packet visible to MQTT subscribers
  • âš  Full GPS precision shared
  • âš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !73ab1026
Position Precision: 32 bits (~1.0m accuracy)
Position precision meters: 1.0
Zero Hop Policy: Enabled
Direct gateway connection
Signal Metrics: RSSI: -77.0 dBm
