本文主要目的是介绍壳常用的反逆向技术，同时也探讨了可以用来躲过或禁用这些保护的技术及公开可用的工具。这些信息将使研究人员特别是恶意代码分析人员在分析加壳的恶意代码时能识别出这些技术，当这些反逆向技术阻碍其成功分析时能决定下一步的动作。-The purpose of this article is to introduce shell of anti-reversing techniques, and also discusses can be used to escape or disable these technologies and tools of publicly available. These messages will enable researchers especially malicious code in packers analysis of malicious code can identify these techniques, when these anti-reversing techniques to restrict its successful analysis can decide the next action.
