MQTT Privacy & Exposure Analysis

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

Exposure Level: Direct Message

Privacy Features:

✓ Direct LoRa transmission (not via MQTT)
✓ Acknowledgment requested
✓ Targeted to specific node
✓ Gateway node ID tracked

Exposure Risks:

⚠ Default channel - no encryption
⚠ Packet visible to MQTT subscribers
⚠ Multi-hop path visible (7 hops)
⚠ RF signal metrics exposed (location inference possible)

MQTT-Specific Fields

Want ack:	`True`
Gateway ID:	`!efffff02`
Signal Metrics:	SNR: 6.50 dB
