It is spoofing, but it is also absolutely amplification. Look at the preso that Damien linked : https://www.usenix.org/conference/woot14/workshop-program/presentation/kuhrer Hope that this doesn't become one of the 'services' that you provide! :) On Thu, Feb 20, 2020 at 6:40 PM Jean | ddostest.me via NANOG < nanog () nanog org> wrote:
It doesn't sound to be a real amplification.. If it is, can anyone provide the amplification factor? 1x? It sounds more like a TCP spoofing.

Which is honestly not their fault because they try to keep their costs down. (Other means to keep the costs down may be of concern of Ronald G. though, but that's a different story.) However, TCP amplification is not of that sort. -- Töma
