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:

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

MQTT-Specific Fields

Gateway ID:	`!000000af`
Zero Hop Policy:	Enabled Direct gateway connection
Signal Metrics:	RSSI: -32.0 dBm SNR: 13.25 dB
