Who ever launched this attack was extremely clever, because they launched the first DDoS early in the morning, then launch the second about 3 hours later, then an hour later, then 30 minutes later, etc. So as they attempted to mitigate the attack, the attacks became bigger and more frequent. This was likely someone testing their capabilities.
I would guess this entire thing was a test. They likely just proved their DNS management vulnerability theory. Now imagine if follow up attacks target multiple DNS managers and servers including Google’s and Facebooks. You could probably take down 99% of the Internet.
Now imagine how much power millions of devices can generate. Small devices like cameras are going to be the bane of the internet. But I have to admit that I can’t wait to see how will root name servers cope with this.
