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
- ✓ Zero-hop: direct from source to MQTT gateway
Exposure Risks:
- âš Visible to all nodes on channel
- âš Default channel - no encryption
- âš Packet visible to MQTT subscribers
- âš RF signal metrics exposed (location inference possible)
