This paper aims to understand empirically the impact of a largescale spamming botnet, and the effectiveness of targeting its core infrastructure ‐ CC specifically, we note the steady growth of the botnet’s size and the rapid version transition after the shutdown of C&C servers. We also estimate the entire size of Srizbi botnet. We then study how the botnet membership is distributed around the globe and how its size changed over time.
