概述：脱壳是一门艺术，它绝对是对你智力上的一种挑战，有的老外把它比作是逆向工程
领域中最令人兴奋思维游戏之一。（感觉这个比喻挺别扭的，呵呵。）一般而言，搞逆向
的哥们必须要了解一定的操作系统内核的知识才能弄懂一些壳中运用的牛逼的反逆向技术
。耐心和头脑是决定你能否脱壳成功的至关重要的两个因素。脱壳其实是个统称，它涉及
到两个方面，一是写壳，一是把写出来的壳给脱掉。
我写这篇文章的首要目的是想和大家探讨一下壳中运用的反逆向技术、分享一些在逆向工
程中用到的工具。对于那些搞研究的，尤其是那些分析恶意代码的哥们，当你被壳中的一
些反逆向代码迷惑的时候，看一下这篇文章吧！你一会从中受益的。其次，我公布了这篇
文章之后，一些更高级的壳就会被开发出来并被运用到软件当中来减慢软件被逆向的速度

壳出来，对你也是小菜一碟吧 。

Abstract: Unpacking is an art—it is a mental challenge and is one of the most
exciting mind games in the reverse engineering field. In some cases, the
reverser needs to know the internals of the operating system in order to
identify or solve very difficult anti-reversing tricks
employed by packers/protectors, patience and cleverness are also major
factors in a successful unpack. This challenge involves researchers creating
the packers and on the other side, the researchers that are determined to
bypass these protections.
The main purpose of this paper is to present anti-reversing techniques employed by executable packers/protectors and also discusses techniques and publicly available tools that can be used to bypass or disable this protections. This information will allow researchers, especially, malcode analysts to identify these techniques when utilized by packed malicious code, and then be able decide the next move when these anti-reversing techniques impede successful analysis. As a secondary purpose, the information presented can also be used by researchers that are planning to add some level of protection in their software by slowing down reversers from analyzing their protected code, but of course, nothing will stop a skilled, informed, and determined reverser.
Keywords: reverse engineering, packers, protectors, anti-debugging, anti reversing
In the reverse engineering field, packers are one of the most interesting
puzzles to solve. In the process of solving these puzzles, the reverser gains
more knowledge about a lot of things such operating system internals,
reversing tricks, tools and techniques. Packers (the term used in this paper
for both compressors and protectors) are created to protect an executable from analysis. They are used legitimately by commercial applications to prevent information disclosure, tampering and piracy. Unfortunately, malcodes also use packers for the same reasons but for a malicious purpose.
Due to a large number of packed malcode, researchers and malcode analysts
started to develop the skills to unpack samples for analysis. However, as time goes by, new anti-reversing techniques are constantly added into packers to prevent reversers from analyzing the protected executable and preventing a successful unpack. And the cycle goes on - new anti-reversing techniques are developed while reversers on the other side of the fence develop the skills, techniques, and tools to defeat them.
最近想翻译一些外文资料，由于本人是新手 ，所以先找个练手的资料 在外文区找了半天精华
发现了一篇 《脱壳的艺术》，已经又大牛翻译过了，如果我翻译过程中遇到不懂的也可以参考一下大牛的文章 呵呵
我只翻译了一部分，我对翻译的理解是 没必要一字一句的翻译，在保证文章意思不变的情况下
完全可以加入自己的话润色一下 这样使文章不再生硬，阅读起来也更爽一些，现在按照这个原则
翻译出来一部分 ，欢迎大家批评指正！
