Question

我正在运行1.5.25，不知何故.htaccess文件不断在我的根目录上创建。

ErrorDocument 400 http:// redirected url index.php

我想知道如何删除创建此.htaccess文件的人员。有没有找出哪个脚本创建这个？哪个用户创建它？

之前有过这个问题的人吗？有没有办法可以创建一个.htaccess并禁止它被改变。应用644权限设置似乎没有帮助。

注意：我已将实际重定向网址更改为重定向网址index.php

Answer 1

Erm权限644表示文件是可写的 - 至少由所有者写。我不知道服务器的设置方式以及所有者是您（ftp用户）还是“无人”Web服务器。

您可能有过时版本的Joomla漏洞或过时且易受攻击的附加组件。有人使用漏洞将“Web shell”放入文件系统的可能性很高。这允许他连接到文件并为他提供一个控制面板选项来编辑文件，上传文件，运行任意命令。

可能是服务器上的另一个帐户遭到入侵，然后该帐户中的文件伸出并在服务器范围内进行编辑 - 或者至少在服务器上的任何可写文件/文件夹上进行编辑。

您应该从网络安全专家那里获得帮助，但如果您想尝试自己进行分析，请执行以下几个步骤。

在服务器上，您还可以使用“查找”命令搜索文件系统，以查找过去x天或最近x小时内更改的文件。

您需要使网站脱机，与主持人联系并解释问题并查看他们可以提供的信息。你应该下载你的文件，作为第一个措施，通过一个功能强大的病毒扫描程序运行（这些扫描程序现在识别大多数网络外壳）。

在文件中搜索以下单词/模式 - grep或类似对此有用：

幅\ S *壳

遭到黑客攻击\ S *由

R57

C99

BASE64_DECODE

带\ s *的行是正则表达式。最后一个会提供许多误报 - 检查每个文件是否有任何可疑的文件，看起来不像Joomla代码的文件（显然需要一点点熟悉）。

升级Joomla以及任何具有更多最新版本的附加组件。首先搜索http://exploit-db.com/搜索“joomla”，然后查看是否列出了任何加载项。

http://www.exploit-db.com/search/?action=search&filter_page=1&filter_exploit_text=joomla&filter_platform=0&filter_type=0&filter_lang_id=0

还有许多其他事情可以检查，可能应该检查 - 但这些是一个很好的起点 - 但我强调最好保留有经验的人的帮助。去黑客服务的起价通常为500英镑，最高可达1000英镑（800美元至1600美元）。

当您将网站重新进行实时检查时 register_globals已关闭短开标签已关闭

确保通过php.ini中的disable_functions指令禁用以下功能 disable_functions选项= EXEC，中继，了shell_exec，系统，proc_open，POPEN，curl_exec，curl_multi_exec，parse_ini_file，show_source

Answer 2

对于安全的Joomla网站，您可以使用以下代码，只需编辑您的.htaccess文件及以下邮件，即可为Joomla网站提供全面保护。它还将使用Joomla Core SEF更新您的URL（您必须启用它）。转到Admin面板并更新Apache的Mode / ReadWrite。

您可以使用以下代码

Answer 4

我有一个严重的问题，有人入侵我的.htaccess文件，我唯一的解决办法是让文件不可攻击。首先，我清理了.htaccess文件和所有黑客的任何PHP文件。然后我在.htaccess文件上将文件权限更改为444（644仍允许访问）。然后我使用shell访问我的帐户使文件“不可变”，这意味着它无法更改！

如果您在Linux服务器上拥有对帐户的shell访问权限，输入以下内容：#chattr + i .htaccess

现在，即使是那些具有root访问权限的人也无法更改文件！

您需要撤消此操作，请输入：#chattr -i .htaccess

如果您没有对帐户的shell访问权限，请向您的Web主机询问是否输入此文件，以使文件不可变。
