Awesome ESP32 Security: Curated Tools & Resources
A curated list of ESP32 security tools, firmware analysis frameworks, and IoT research resources for penetration testers and hardware hackers.
Overview
The ESP32 is the most ubiquitous IoT microcontroller. Its built-in Wi-Fi, Bluetooth, and BLE make it a prime target for security research, and a powerful platform for building audit tools.
This article is a living index of the best ESP32 security resources.
Firmware analysis
| Tool | Description |
|---|---|
| ESP32-HARNESS | Custom pentesting firmware — 2.4 GHz audit, RF24, forensics |
| esp32-hacking-guide | Complete guide: firmware analysis, WiFi attacks, BLE exploitation |
| esptool | Official Espressif flash tool — dump, write, verify flash |
| esp-idf | Official SDK — build custom firmware from source |
Wireless auditing
- WiFi: Promiscuous mode sniffing with ESP32 radio
- BLE: Passive scanning with
esp_ble_gap_start_scanning() - RF24: NRF24L01+ integration for sub-GHz research
On-device forensics
The ESP32-HARNESS firmware exposes captured data over USB mass storage, allowing forensic extraction without additional hardware:
[ESP32] ←UART→ [Host] — capture to flash
[ESP32] ←USB→ [Host] — mount as FAT, extract logsRelated resources
