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
- ✓ Reduced position precision: ~1500.0m accuracy
Exposure Risks:
- âš Visible to all nodes on channel
- âš Default channel - no encryption
- âš Packet visible to MQTT subscribers
- âš Multi-hop path visible (1 hops)
- âš RF signal metrics exposed (location inference possible)
