I use a couple of TP-Link smart power plugs and one of them occasionally wants to access the internet to get the time from an NTP server. Since I block all their internet access this one goes crazy and brings my DNS server (custom written in Python) down to a halt. Just blocking him in the firewall of the AP would probably also not make him behave and he'd still pollute the RF spectrum. Happens rarely, though. Kicking him off of the WiFi and letting him reconnect makes him behave again.
Funnily enough that happens also when you run the original article through Google translate:
> She's in the bathroom at home, but she's part of a large-scale cyber attack. The electric toothbrush is programmed with Java, and criminals have unnoticed installed malware on it - like on 3 million other toothbrushes.
(In German, toothbrushes are female, like all brushes.)
If he were a good boy, he would listen to what is told to him by the DHCP server and use the local NTP server instead (not only is it closer but it's also fed by PPS-accurate GPS data).
