PPC (Pay Per Click) Botnet

看到第一個 PPC Botnet 被發現的消息:Clickbots vs AdSense and Others,不過目前看起來還是蠻傳統的方法控制 (透過 Web servers 抓資料):

The bots are controlled remotely through several Web servers.

理想中的狀態應該是 Botnet 本身是 P2P Network,再透過數位簽章的方式丟指令叫 Botnet 做,使得整個 Botnet 建立後就沒有 single point of failure,而且這樣會大幅提昇 Spammer 的隱密性...
