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“ Custom channel: MediumSlow
  • โœ“ Gateway node ID tracked
  • โœ“ Zero-hop: direct from source to MQTT gateway
Exposure Risks:
  • โš  Visible to all nodes on channel
  • โš  Packet visible to MQTT subscribers
  • โš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !b03de73c
Zero Hop Policy: Enabled
Direct gateway connection
Signal Metrics: RSSI: -115.0 dBm
SNR: -9.50 dB
