摘 要：In this report, we fill in some of these gaps by analyzing the “auto-clicking” and “search-hijacking” modules that drive most of ZeroAccess’s revenue creation. Using a combination of code analysis and empirical measurement, we document the distinct command and control protocols used by each module, the infrastructure they use, and how they operate to defraud online advertisers.
