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

Exposure Risks:

⚠ Visible to all nodes on channel
⚠ Default channel - no encryption
⚠ Packet visible to MQTT subscribers
⚠ Multi-hop path visible (2 hops)
⚠ RF signal metrics exposed (location inference possible)

MQTT-Specific Fields

Gateway ID:	`!67aa5049`
Signal Metrics:	RSSI: -115.0 dBm SNR: -4.75 dB
