NodeMCU, an open-source development platform based on the ESP8266, has become a significant tool in network security testing. This article investigates the use of NodeMCU in attacks against Wi-Fi networks on the 2.4 GHz frequency. We conducted experiments to launch NodeMCU's capabilities to exploit security weaknesses in Wi-Fi networks, including attacks against WEP, WPA, and WPA2 encryption. We also present preventive measures that can be implemented to protect Wi-Fi networks from attacks possible using NodeMCU. Keywords: NodeMCU, ESP8266, Wi-Fi network, security attack, encryption, WEP, WPA, WPA2
