MQTT Privacy & Exposure Analysis

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

Nivo izloženosti: Broadcast

Opcije privatnosti:

✓ Direct LoRa transmission (not via MQTT)
✓ Custom channel: Srbija
✓ Gateway node ID tracked

Rizici izloženosti:

⚠ Visible to all nodes on channel
⚠ Packet visible to MQTT subscribers
⚠ Multi-hop path visible (4 hops)
⚠ RF signal metrics exposed (location inference possible)
