MQTT Privacy & Exposure Analysis

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

Nivo izloženosti: Direct Message

Opcije privatnosti:

✓ Direct LoRa transmission (not via MQTT)
✓ Targeted to specific node
✓ Custom channel: MediumFast
✓ Gateway node ID tracked

Rizici izloženosti:

⚠ Packet visible to MQTT subscribers
⚠ Multi-hop path visible (1 hops)
⚠ RF signal metrics exposed (location inference possible)
