MQTT Privacy & Exposure Analysis

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

Exposure Level: Broadcast
Privacy Features:
  • āœ“ Direct LoRa transmission (not via MQTT)
  • āœ“ Custom channel: Almeria
  • āœ“ Gateway node ID tracked
Exposure Risks:
  • āš  Visible to all nodes on channel
  • āš  Packet visible to MQTT subscribers
  • āš  Multi-hop path visible (3 hops)
  • āš  RF signal metrics exposed (location inference possible)
