如何解码JSFuck脚本? [英] How to decode a JSFuck script?

问题描述

我在JavaScript中有以下代码:

I have this code in JavaScript:

[(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]

在控制台中，它将返回

Array [ "filter" ]

我该如何解码很多与上面的文本相似的文本?例如:

And how can I decode a lot of text that’s similar to the text above? E.g.:

[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+
(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]][([][(![]+[])[+[]]+
([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+
(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+
(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+
([][[]]+[])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[+!+[]]+([][[]]+[])[+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[][(![]+[])[+[]]+
([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+(!![]+[])[+!+[]]]

我想看普通的脚本.

推荐答案

我看到了很多解码尝试，但是都没有可靠的方法.我发现对非字母数字Javascript进行解码的最简单方法是使用Chrome.

I have seen many decoding attempts around, but none that work reliably. The easiest way I have found to decode Non Alphanumeric Javascript is with Chrome.

打开Chrome>转到jsfuck.com>将要解码的代码粘贴到窗口中，然后单击运行此".

Open Chrome > Go to jsfuck.com > paste the code you would like to decode in the window > hit Run This.

然后打开控制台，如果您的来自PasteBin的特定代码会出现错误:

Then open the Console, in the case of your specific code from PasteBin there will be an error:

Uncaught TypeError: Cannot read property 'innerHTML' of null  

在错误的右侧，单击行号链接，然后将显示代码.结果是:

To the right of the error, click the line number link, and the code will be revealed. The result is:

(function(){
    window.false=document.getElementById('sc').innerHTML;
})

这将解释为什么您会收到尝试仅使用JSFuck本身对其进行解码的错误的原因.网站上没有ID为sc的元素.

Which explains why you get the error trying to just decode it using JSFuck itself. There is no element with the id sc on their site.
