我刚刚下载了一个“免费”主题,用我使用的插件检查了文件(http://builtbackwards.com/projects/tac/)
有史以来第一次提出“加密代码发现!”所以我一直试图弄清楚这段代码是什么(没有任何运气,我可能会添加)
无论如何我在这里问这个代码中是否有任何“坏”(如果有人比我工作更幸运)

要点什么
eval
几乎可以肯定是糟糕的代码。它的作用很难说 - 它可能是从您的网站窃取一些数据,出于某种原因打电话回家或提示用户下载木马或病毒。
这是下载第三方代码的问题,而不是先获得一些信任并理解代码的作用。

解码这就是代码的样子:

我将看看它的作用。乍一看看起来不像恶意,有点跟踪代码和页脚代码(版权和内容)。
