Case study
ESP32 RF/IoT Security Toolkit
ESP32-based toolkit for auditing RF and Wi-Fi IoT device security in authorized test environments.
ESP32RFNetworking ProtocolsSecurity
Scan coverage
2.4GHz + sub-GHz
Device cost
<$25 in parts
Audit time per device
~10 min
Problem
IoT deployments (including industrial ones) often ship with weak or default RF/Wi-Fi configurations. Needed a portable, low-cost tool to audit deployed devices for common misconfigurations before rollout, in explicitly authorized engagements.
Stack
- ESP32 (dual-core, Wi-Fi/BLE)
- nRF24L01 sub-GHz module
- C/C++ (ESP-IDF)
- Custom packet capture UI
Architecture
Outcome
Used in pre-deployment audits to catch unauthenticated command channels and default AP credentials before industrial IoT devices went live, closing exposure windows before commissioning.
