所以我在我的垃圾邮件文件夹中查找并发现此消息：

  

有用的ΜеmЬег，

     

我们正在努力让你能够完全解决这个问题吗？   ΑссοuntRеvіеwΤеаm。

     

Оuг，据说这样做是不可能的，因为它可以解释   喜欢你自己的事。

附在电子邮件中的是“Verification_2015.html”

代码对于'stackoverflow'来说太大了，所以可以在这里找到：http://pastebin.com/UxcGwSv7

我尝试使用几个解码器对其进行解码，我发现这些解码器在互联网上徘徊，但都没有用，我猜这里有一些高级的javascript编码，我无法弄明白。

有人可以：

  • （A）指出我正确的解释方法。
  • （B）向我解释如何解码这个以及它的内部运作。
  • 或（C）为我解码。

先谢谢你，

2 个答案:

答案 0 :(得分：3)

生成JavaScript的混淆JavaScript（例如，不是作为某种解释器运行）很容易解码！只需寻找将变换后的字符串转换为某种“真实世界”动作的部分。在这里，它是document.write，您可以将其替换为console.log并直接生成HTML。

这是通过tidyhtml运行的：

答案 1 :(得分：1)

我想我昨天才得到这个特别的信息。 Avast在通过Outlook下载时最终标记了它，我想今天看看它。我收到的附件似乎与你的相同。让我们专注于剧本。

第一行function BDE(r)看起来像是各种解码器。查看调用此函数的第二行，BDE()显然是base64解码器。第二行调用它将base64转换为blob并将其存储在BSs。

如果您解码base64字符串，您会注意到结果不是完全可读的。查看脚本的其余部分，很明显解码后的结果是通过另一个函数提供的，并且在被该函数转换后，应该会产生类似于HTML的内容。第三行是有趣的地方。这里的代码是美化的：

function XD1(r, t) {
    var n = [],
    o = "";
    for (z = 1; 255 >= z; z++) n[String.fromCharCode(z)] = z;
    for (j = z = 0; z < r.length; z++) o += String.fromCharCode(n[r.substr(z, 1)] ^ n[t.substr(j, 1)]), j = j < t.length ? j + 1 : 0;
    return o
}

变量n是一个数组，初始化值为0到255，如第3行所示。我们称之为＆＃34;密码表＆＃34;。 o是返回值。第四行是真正的工作完成的地方。请注意，r是要解密的内容，t是关键。循环对内容中的每个字节执行的操作是，它使用该字节索引到密码表中，同时从密钥中依次选取一个字节并使用它来索引到密码表。两个结果字节一起进行异或，转换为字符，并附加到结果中。使用表而不是直接使用XORing的原因是因为字符串XOR字符串不会产生有用的结果。相反，通过索引到表中，接收两个数字，可以将它们一起进行异或，并且结果可以转换为字符。最后，这是您的标准XOR密码。

关于解密循环的一个有趣的怪癖是这个片段：j = j < t.length ? j + 1 : 0。当您遇到j小于t.length的情况时，j仍然会增加，并导致尝试使用超出范围的索引t。 substr()返回0，当使用XOR密码的正确实现时，它会有效地在密钥的末尾添加一个空字符。

父脚本的最后一行将解密数据写入文档，这是一个简单的HTML页面，其中包含用于提交信用卡信息的表单。

摘要：脚本base64解码，然后XOR解密数据，并将其写入页面。
