@GossiTheDog @Euph0r14 @mttaggart @barubary @serghei I tried doing some rudimentary german language searches for big DDoS attacks against Swiss companies and didn’t find something which would fit (would have certainly been in the news?)
Nothing mentioning 3 million devices.
I did find ddos attacks from ~2016 against Major Swiss online shopping sites, so maybe this could be meant? They went down for a few hours and could have done millions in damages.
