"use of the new 'fluxxy' fast flux infrastructure"
On reading this line, I thought that there are some smart criminals out there. Curious, I looked it up. This fast-flux thingy is basically the botnet being able to rewrite DNS records every minute because the registrar doesn't give a flying monkey's about it.
So these crims are smart, but if every registrar did its job properly, this technique would not survive.
