PHP木马清理过程
一个朋友网站 ,有不明文件,让我查看查看。
上去看了一下,发现多出好多文件,而且莫名奇妙出现广告页。
先删除了多余页面,以为没事,却发现广告的链接依旧,
后查找广告地址,发现 是写在.htaccess 文件里指向某个txt 作为网页打开。
于是把.htaccess文件给禁止掉。
=========================
apache禁止后缀的方法:
这里就只演示下怎么禁止php执行,其他的稍微简单改了就好.在你要禁止的目录下新建个.htaccess,内容为:
代码如下 复制代码
Order Allow,Deny
Deny from all
或者
在需要的目录下建立一个 .htaccess 文件并在里面写上一行
代码如下 复制代码
php_flag engine off{
}
=============================
可是又发现几天陆续出现大量文件上传上来。
于是禁止一些目录上传。但是有些目录还是大量的上传,看来这个黑客不死心。
想着 这个黑客搞上传文件,一定是通过某个木马程序上传的,得找出这个木马,
既然他能上传文件,那么应该会用到文件读写函数,于是查找
grep -color -i -r -n "fwrite" /opt/FTP/root
果然发现有个木马文件,你们是完全的操作服务上传文件。。干掉以后,才系统安稳了。
