![]() ![]() The code should also display the collected data on the Serial Monitor. ![]() Open the Arduino IDE or Lua editor and write a code to collect data from the sensor and send it to ThingSpeak using the Wi-Fi module of NodeMCU. The VCC and GND pins should be connected to the 3V3 and G pins on NodeMCU, respectively. The BMP280 has SDA and SCL pins that should be connected to D2 and D1 pins on NodeMCU, respectively. Phase 1: Collecting Data from Sensor and Sending to ThingSpeakĬonnect the BMP280 sensor to NodeMCU. MacBook or any other computer with Wireshark and Mitmproxy installed.Finally, we implement Elliptic Curve Cryptography to secure the data being sent from NodeMCU to the server. In the second phase, we demonstrate how to perform a MITM attack on NodeMCU using a MacBook as the attacker machine. NodeMCU then sends this data to ThingSpeak, a cloud-based IoT platform, using its built-in Wi-Fi module. ![]() In the first phase, we connect a BMP280 sensor to NodeMCU and collect temperature, barometric pressure, and altitude data from the sensor. This project demonstrates how to perform a MITM attack on NodeMCU and how to prevent it using Elliptic Curve Cryptography. However, it is vulnerable to Man-in-the-Middle (MITM) attacks, where an attacker can intercept and steal the data being sent from NodeMCU to the server. It can be programmed using Lua or Arduino IDE, and is widely used in many IoT projects. The NodeMCU ESP8266 is a popular Internet of Things (IoT) device that uses built-in Wi-Fi to connect to the internet. The project demonstrates how an attacker can intercept the data being sent from NodeMCU to a server using ARP spoofing and how the data can be stolen as it is sent over the network in plaintext. This project showcases a vulnerability in NodeMCU ESP8266 that allows man-in-the-middle (MITM) attacks to be easily possible on the IoT device and steal the data that is being sent from NodeMCU to the server. ![]()
