Mais alguma informação que me esqueci de partilhar.
A página da wikipedia sobre botnets também aborda a arquitetura escrita no OP e passa a ideia que é algo "novo" apesar de não fazer muito sentido.
>Peer-to-peer
>A peer-to-peer (P2P) network in which interconnected nodes ("peers") share resources among each other without the use of a centralized administrative system
>In response to efforts to detect and decapitate IRC botnets, bot herders have begun deploying malware on peer-to-peer networks. These bots may use digital signatures so that only someone with access to the private key can control the botnet.[8] See e.g. Gameover ZeuS and ZeroAccess botnet.
>Newer botnets fully operate over P2P networks. Rather than communicate with a centralized server, P2P bots perform as both a command distribution server and a client which receives commands.[9] This avoids having any single point of failure, which is an issue for centralized botnets.
>In order to find other infected machines, the bot discreetly probes random IP addresses until it contacts another infected machine. The contacted bot replies with information such as its software version and list of known bots. If one of the bots' version is lower than the other, they will initiate a file transfer to update.[8] This way, each bot grows its list of infected machines and updates itself by periodically communicating to all known bots.

Lá surgem estes dois exemplos adicionais, que (apesar de mais recentes) também parecem já não ser muito relevantes.
<ZeroAccess botnet
>In December 2013 a coalition led by Microsoft moved to destroy the command and control network for the botnet. The attack was ineffective though because not all C&C were seized, and its peer-to-peer command and control component was unaffected - meaning the botnet could still be updated at will.[8]
Isto valida a ideia de mais resiliência que tinha falado no mundo real, apesar de ser bastante óbvia e não precisar de grandes provas.
