What it does

LoRaWAN and sub-GHz (433 / 868 / 915 MHz) attack methodology, LoRaWAN ABP/OTAA join attack, network/session key reuse, frame counter replay, downlink injection on TTN/Helium-style networks, sub-GHz protocol replay (KeeLoq garage doors, fixed-code remotes, TPMS spoofing, smart plug telemetry), HackRF / RTL-SDR / Flipper Zero workflows, signal analysis with Inspectrum / Universal Radio Hacker, and reconstruction of proprietary packet formats. Use for LoRaWAN deployments (smart cities, asset tracking, industrial telemetry), or any wireless device using the unlicensed 433/868/915 MHz bands (garage openers, doorbells, IoT sensors, RC equipment).

LoRaWAN & Sub-GHz Attacks

LoRaWAN provides long-range low-bitrate communication for IoT, common in smart cities, asset tracking, and industrial telemetry. Outside LoRaWAN, the 433 / 868 / 915 MHz ISM bands host garage doors, doorbells, smart plugs, weather stations, and TPMS, most with weak or no crypto.

Quick Workflow

  1. Identify the band + modulation (LoRa CSS vs. simple OOK/FSK)
  2. Capture transmissions with appropriate hardware (HackRF / RTL-SDR / Flipper Zero)
  3. For LoRaWAN: capture join + uplinks; analyze key derivation
  4. For proprietary sub-GHz: demodulate, identify packet format, replay or craft

LoRaWAN

LoRaWAN is a MAC layer over LoRa physical (chirp spread spectrum). Devices either:

  • OTAA (Over-the-Air Activation), derive session keys at join
  • ABP (Activation By Personalization), pre-flashed keys

OTAA Join Capture

# Capture LoRa packets with HackRF + Inspectrum
hackrf_transfer -r capture.iq -f 868000000 -s 1000000 -n 60000000
# Or LoRa-specific: rak_common_for_gateway

# Decode with PHY + MAC stack
git clone https://github.com/Lora-net/LoRaMac-node
# Or use ChirpStack as a sniffing gateway

The Join-Request and Join-Accept are encrypted with the device's AppKey. With AppKey (extracted from device firmware, see offensive-iot):

  • Decrypt Join-Accept → recover NwkSKey, AppSKey
  • Subsequent traffic decryption + injection

ABP, Pre-Flashed Keys

ABP devices have NwkSKey + AppSKey flashed at manufacture. Common flaws:
