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
  • โœ“ Reduced position precision: ~2900.0m accuracy
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)
MQTT-Specific Fields
Gateway ID: !b03da004
Position Precision: 13 bits (~2900.0m accuracy)
Position precision meters: 2900.0
Signal Metrics: RSSI: -125.0 dBm
SNR: -11.75 dB
