Doorway botnet: exposed operator files show 59 exploits for cameras, routers and ONUs and thousands of hijacked MikroTik devices

CloudSEK published a report on 28 October 2026 about a botnet it calls Doorway. In October its researchers found two identical open directories left exposed by the operators, holding about 41 GB of working data: source code, scan results, logs and notes. That gives an unusually direct look at how a campaign against home and small office network gea

Tasmota: flash an ESP-based plug or switch and control it locally over MQTT

Plenty of cheap Wi-Fi plugs, relays and switches are built around an Espressif chip and ship with firmware that talks only to the manufacturer's cloud. Tasmota replaces that firmware with an open one that runs entirely on your network: a web page on the device, a console, timers and rules on the device itself, and MQTT for anything bigger. This gui

How to choose a smart plug with local control and energy metering

A smart plug is the cheapest way to automate something and the easiest way to find out what a device really uses. It is also the product category where it is easiest to buy the wrong thing: a plug that only works through an app and a remote server, a relay too weak for a heater, or a metering chip that reports once a minute when you wanted live dat

Wi-Fi HaLow in Europe: what long-range Wi-Fi can do for IoT and where it falls short

Wi-Fi HaLow promises something that sounds ideal for a house with a large garden, a detached garage or an allotment: Wi-Fi that reaches about a kilometre, passes through walls and runs a sensor on a battery for months. Modules, Raspberry Pi add-on boards and small routers have started to appear. Before you buy, though, it helps to know that HaLow i

Program an ESP32 in the Arduino IDE: install the board package, upload a sketch and serve a web page

ESPHome and Tasmota cover a lot of home projects without writing code, but sooner or later you may want firmware that does exactly what you need and nothing else. The Arduino IDE with Espressif's own Arduino core (arduino-esp32) is the most common way to write that firmware in C++. This guide takes you from a fresh Arduino IDE 2 installation to an
