Transparency and Semantics Coexist: When Malware Analysis Meets the Hardware Assisted Virtualization

Modern malware attacks are designed intricately, transport data encrypted, so monitoring network traffic can't solve such attacks completely. Therefore, network monitoring and analysis need to be combined with system behavior monitoring and memory analysis, and the latter is more important. In this article we propose a hardware-based virtualization prototype system, combined with memory analysis tools to monitor and counterwork malicious attacks actively. The system is based on Xen virtualization platform, which monitoring virtual machine behavior by capturing specific events. The events are triggered by some specific behaviors associated with malicious software monitoring, such as executing privileged instruction, system calls, memory writing, etc. When necessary, we can dump the memory of the virtual machine, use memory analysis tools for detailed analysis, so as to achieve the purpose of monitoring and counterworking.
