Network Virtualisation

Could dynamic Malware analysis be more dynamic by §assigning network calls an injected result, defined §by the analysis process? Yes, but only if the §network access was completely virtualised. This book §explains how this virtualisation could be achieved. §It starts with an instruction of dynamic Malware §analysis and the usage of sockets in the Windows §operating system. By using Qemu and TTAnalyze (a §tool for dynamic Malware analysis), it describes how §network access could be virtualised, so that system §calls relating to sockets (and therefore accessing §the network) are intercepted at the system call §gate, then manipulated and imitated for a dynamic §analysis. The book also defines the most important §synchronisation techniques of multi-threaded §applications for their (network) activities. The §reader will gain a thorough understanding, of how §high level functions of the Winsock library are §executed with the aim of system calls.
