Finland, sub-zero temperatures, snow and cold on the street. You get home, you turn on the heating and… It doesn't work. Will the boiler have broken, maybe the thermostat? No, the reason is a cyberattack. This is what has happened in the Finnish village of Lappeenranta, near the border with Russia.
Cybercriminals launched the attack on the central heating system, causing the population to be left without heating or hot water for more than a week.
According to the analyses carried out, everything seems to indicate that the attack has been perpetrated by the botnet Mirai, that takes advantage of vulnerabilities in IoT devices to launch these attacks and render the target serviceless, as happened a few weeks ago in the attack that brought down half the Internet.
