javascript - 帮助反混淆此 JS 攻击

我有一段讨厌的 javascript,我想去混淆。我知道我可以启动一个 VM 并看到恶意软件的所有荣耀,但我更感兴趣的是不让它运行,而是以非混淆的形式查看它。如果它需要运行才能执行此操作,那么就这样吧,我想。有人知道如何在不损害自己的情况下做到这一点吗?

谢谢,蒂姆

再次编辑:我选择 Matthew Flaschen 是因为在仔细研究之后,他、Russ Cam 和其他人帮助阐明了这种特殊攻击的作用以及一般情况下如何处理这类事情.马修碰巧跳得最快。

注意:在试图查明这个问题的过程中,我发现了一个非常方便的工具 Malzilla。如果您需要做这类事情,它有很多实用的工具。谢谢大家!

此木马称为 Twitini.A,记录在此处:http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Trojan%3AJS%2FTwitini.A

在谷歌搜索之前,我在自己的标本上深入了 2 层。我真的对推特的搭配很感兴趣。我认为在特定日期使用已知的 Twitter 趋势来生成域名是很聪明的。
