There is a truly excellent video on Mirai's (the botnet or atleast code in question) origin. It was created in the Minecraft server community by teenagers. The botnet was huge to a point where Akamai had to get help from Google to mitigate an attack on krebs' security blog. It also was used to attack Dyn, the infrastructure provider, and resulted in a huge outage affecting Netflix, Twitter etc.<p>Sadly it's only in German, but if you are on desktop, you can auto-translate the subtitles.<p><a href="https://www.youtube.com/watch?v=uletKRPMnuo" rel="nofollow">https://www.youtube.com/watch?v=uletKRPMnuo</a>
