Getting Started with ESP8266 NodeMcu v3

November 5, 2019 by Kalitut Leave a Comment

NodeMcu is an ESP8266 based platform for creating various Internet of Things (IoT) devices. The module can send and receive information to a local network or to the Internet using WiFi. An inexpensive module is often used to create distance-controlled smart home systems or Arduino robots. In this article, we will look at the board description, version differences, and NodeMcu v3 pinout the latest version of the NodeMcu Esp8266 module . We will also briefly review the Lua language in which you need to write programs for NodeMcu.

NodeMCU esp8266 WiFi Jammer

April 28, 2019 by Kalitut 1 Comment

nodemcu wifi jammer, WiFi Jammer is a gadget that is designed to disable wireless devices from hotpots. Why do you need it? You can imagine yourself as a friendly joke (a neighbor, of course, will be delighted when you cut off his Netflix or for example, a football match at the most interesting place) or a criminal application: an attacker can disconnect security cameras or other important equipment from the network. In this article we will discuss what are the inexpensive options for hardware deauthenticators, how to use them and how to protect against such attacks.

How does this “nodemcu wifi jammer” work
Unlike real jammers, which interrupt the signal of a radio transmitter with its stronger signal, the deauthenticator works at the program level. It implements a denial of service attack by sending a deauthentication frame to the router on behalf of devices connected to the network. Since this frame is not encrypted in any way, it is enough for a stub to find out the MAC addresses of the devices through the network traffic.
