Reverse Engineering of a Not-so-Secure IoT Device #IoT #InternetOfThings #ReverseEngineering #EE #Wireless @McuOnEclipse
Via McuOnEclipse, when people build “smart things” and “wireless things”, is security a primary consideration? This article focuses on looking at a strange monitoring device found by employees under desks and in meeting rooms, placed there by their employer. What does it do? Erich Styger finds out.
Looking inside:
The analysis of the board component revealed following components:
Microchip RN2483 LoRa module with antenna
STM32L031F6P6 ARM Cortex-M0+ microcontroller
AMSYS HTU20 I2C humidity/temperature sensor
RGB LED indicating connection status
Unknown device 8743 (I2C), probably a magnetometer/accelerometer
Using the logo found on the device, a Google name/image search reveals the company behind this device. The examples on the web site shows that these devices are used for office space monitoring.
The law in many countries is very strict if electronic devices are used to monitor a workplace. The information (or lack of information) what a device can and cannot do very likely will cause lots of employee concerns.
The article goes in depth analysing the device, it’s firmware and more to see what it can do and how the lack of security puts people at risk.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
