Description: BotGraph: large scale spamming botnet detection. Network security applications often require analyzing huge volumes of data to identify abnormal patterns or activities. The emergence of cloud-computing models opens up new opportunities to address this challenge by leveraging the power of parallel computing. In this paper, we design and implement a novel system called BotGraph to detect a new type of botnet spamming attacks targeting major Web email providers. Bot-Graph uncovers the correlations among botnet activities by constructing large user-user graphs and looking for tightly connected subgraph components. This enables us to identify stealthy botnet users that are hard to detect when viewed in isolation. To deal with the huge data volume, we implement BotGraph as a distributed application on a computer cluster, and explore a number of performance optimization techniques. Applying it to two months of Hotmail log containing over 500 million users, BotGraph successfully identified over 26 million botnet-created user accounts with a low false positive rate. The running time of constructing and analyzing a 220GB Hot-mail log is around 1.5 hours with 240 machines. We believe both our graph-based approach and our implementations are generally applicable to a wide class of security applications for analyzing large datasets.
