MQTT Privacy & Exposure Analysis

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

Exposure Level: Direct Message
Privacy Features:
  • āœ“ Direct LoRa transmission (not via MQTT)
  • āœ“ Targeted to specific node
  • āœ“ Gateway node ID tracked
  • āœ“ Zero-hop: direct from source to MQTT gateway
Exposure Risks:
  • āš  Default channel - no encryption
  • āš  Packet visible to MQTT subscribers
  • āš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !c0e216ce
Zero Hop Policy: Enabled
Direct gateway connection
Signal Metrics: RSSI: -117.0 dBm
