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
✓ Zero-hop: direct from source to MQTT gateway

Exposure Risks:

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

MQTT-Specific Fields

Want ack:	`True`
Gateway ID:	`!433cc404`
Zero Hop Policy:	Enabled Direct gateway connection
Signal Metrics:	RSSI: -102.0 dBm SNR: -6.50 dB
