Like the first two parts where I discussed the command and control structure of the Pushdo and Koobface botnets, I'll start by showing the current geographical distribution of Clampi CnCs, followed by a brief analysis on the chances of shutting down these control servers and hence the complete botnet.

This article is not an in depth analysis of the malware itself but concentrates more on current geo locations of Clampi command and control servers. For detailed in-depth analysis of this malware, one may refer to this.
