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)
✓ 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

MQTT-Specific Fields

Gateway ID:	`!0c703019`
Zero Hop Policy:	Enabled Direct gateway connection
