# LoRaWAN OTAA / ABP Security Assessment
> LoRaWAN is deployed globally for smart meters, asset tracking, agriculture,
> and industrial sensors. OTAA (Over-The-Air Activation) derives session keys
> per join; ABP (Activation By Personalization) hardcodes them. Both have
> documented attack surface: OTAA AppKeys are often extracted from the device
> firmware or exposed via insecure provisioning, and ABP devices commonly
> disable the frame-counter check, enabling full replay.
## Prerequisites
- **Hardware**: LILYGO TTGO T-Beam (SX1276 + GPS, programmable SDR-LoRa node),
RAK831 / RAK2247 gateway concentrator, or HackRF One with gr-lora.
RTL-SDR is receive-only (works for capture on EU 868 MHz).
