又一个加密PHP脚本的解码方法
又一个加密PHP脚本的解码方法
三个星期以前我发布了一篇文章,介绍了base64加密的PHP脚本的解码方法。前几天,飞信好友行者又扔来了一段更加复杂、诡异的PHP脚本:
//0.php

其中,在“?>”后面的数据足有27KB(共27316字节)。显然,这些数据并不是直接输出给客户端的,而要在服务端经过一定的处理。这27KB的数据看起来很像base64编码,但是直接用base64_decode解码得不到任何有意义的结果。
仔细观察,在前面的PHP代码部分有一个eval。那就按照上一篇文章的办法,把它改成echo试试!
//1.php

运行方式还是 wget http://localhost/1.php -O1.txt ,运行结果如下:
//1.txt
$OO0OO0000=$OOO000000{17}.$OOO000000{12}.$OOO000000{18}.$OOO000000{5}.$OOO000000{19};if(!0)$O000O0O00=$OO0OO0000($OOO0O0O00,'rb');$OO0OO000O=$OOO000000{17}.$OOO000000{20}.$OOO000000{5}.$OOO000000{9}.$OOO000000{16};$OO0OO00O0=$OOO000000{14}.$OOO000000{0}.$OOO000000{20}.$OOO000000{0}.$OOO000000{20};$OO0OO000O($O000O0O00,1182);$OO00O00O0=($OOO0000O0($OO0OO00O0($OO0OO000O($O000O0O00,908),'I/MNKACdVRGQyDWUgq68wpkazLO5ltnmTB+0bv9uHrxF7XSY1E3fZhijc4e2oJsP=','ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/')));eval($OO00O00O0);
用1.txt的结果替换1.php中那个echo,得到:
//1a.php
<?php

/* 27316 bytes encoded data */
又看到了eval,那就再换成echo吧!遗憾的是,这样做不能得到正确的结果。原因是:
- 文件末有27KB的数据,这些数据应该包含了经过编码的程序代码。
- 开头的解码脚本从__FILE__变量获取当前执行的文件名,然后定位到27KB数据内部的某个位置(可能是开头或中间),解码并执行那些数据中蕴藏的程序。
- 从0.php变换到1a.php的过程中,开头的解码脚本的长度被改变,造成不能定位到正确的位置。
在1a.php已经可以看到三个数字:26408、1182、908。但是,无法判断这些数字将使解码脚本定位到27KB数据的哪个位置。
老路行不通了!现在必须分析这段解码脚本的流程。先把代码整理一下:
<?php
$OOO0O0O00=__FILE__;
$OOO000000=urldecode('%74%68%36%73%62%65%68%71%6c%61%34%63%6f%5f%73%61%64%66%70%6e%72');
$OO00O0000=26408;
$OOO0000O0=$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';
$OO0OO0000=$OOO000000{17}.$OOO000000{12}.$OOO000000{18}.$OOO000000{5}.$OOO000000{19};
if(!0)$O000O0O00=$OO0OO0000($OOO0O0O00,'rb');
$OO0OO000O=$OOO000000{17}.$OOO000000{20}.$OOO000000{5}.$OOO000000{9}.$OOO000000{16};
$OO0OO00O0=$OOO000000{14}.$OOO000000{0}.$OOO000000{20}.$OOO000000{0}.$OOO000000{20};
$OO0OO000O($O000O0O00,1182);
$OO00O00O0=($OOO0000O0($OO0OO00O0($OO0OO000O($O000O0O00,908),'I/MNKACdVRGQyDWUgq68wpkazLO5ltnmTB+0bv9uHrxF7XSY1E3fZhijc4e2oJsP=','ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/')));
eval($OO00O00O0);
return;
?>
/* 27316 bytes encoded data */
然后,便是一行行弄清解码脚本中每个变量的值,这样就可以看懂其流程。例如$OOO000000=urldecode('%74%68%36%73%62%65%68%71%6c%61%34%63%6f%5f%73%61%64%66%70%6e%72');
,可以在其后面加一句die($OOO000000);
,就能看到这个变量的值是'th6sbehqla4co_sadfpnr'
。
对解码脚本的分析结果是:
//1c.php
<?php
$OOO0O0O00=__FILE__;
//$OOO000000=urldecode('%74%68%36%73%62%65%68%71%6c%61%34%63%6f%5f%73%61%64%66%70%6e%72');
$OOO000000='th6sbehqla4co_sadfpnr';
$OO00O0000=26408;
//$OOO0000O0=$OOO000000{4}.$OOO000000{9}.$OOO000000{3}.$OOO000000{5};

$OOO0000O0='base64_decode';
$O0O0000O0='OOO0000O0';

$OO0OO0000='fopen';
//if(!0)$O000O0O00=$OO0OO0000($OOO0O0O00,'rb');
$O000O0O00=fopen($OOO0O0O00,'rb');
//$OO0OO000O=$OOO000000{17}.$OOO000000{20}.$OOO000000{5}.$OOO000000{9}.$OOO000000{16};
$OO0OO000O='fread';
//$OO0OO00O0=$OOO000000{14}.$OOO000000{0}.$OOO000000{20}.$OOO000000{0}.$OOO000000{20};
$OO0OO00O0='strtr';
//$OO0OO000O($O000O0O00,1182);
fread($O000O0O00,1182);
/*$OO00O00O0=($OOO0000O0(

)
);*/
$OO00O00O0=(base64_decode(
strtr(
fread($O000O0O00,908),
'I/MNKACdVRGQyDWUgq68wpkazLO5ltnmTB+0bv9uHrxF7XSY1E3fZhijc4e2oJsP=',
'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'
)
)
);
eval($OO00O00O0);
return;
?>
/* 27316 bytes encoded data */
其中涉及文件操作的,也就是这几句:
$OOO0O0O00=__FILE__;//获取当前文件名
$O000O0O00=fopen($OOO0O0O00,'rb');//打开文件
fread($O000O0O00,1182);//跳过1182字节
$OO00O00O0=(base64_decode(
strtr(
fread($O000O0O00,908),
'I/MNKACdVRGQyDWUgq68wpkazLO5ltnmTB+0bv9uHrxF7XSY1E3fZhijc4e2oJsP=',
'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'
)
)
);//读取908字节,根据代码表替换字符,base64解码
eval($OO00O00O0);//执行解码后的代码
在1a.php中把eval替换为echo之所以行不通,就是因为这里写着的跳过1182字节。跳过1182字节是针对原始文件而言的,修改过后文件大小改变,需要跳过的字节数就不一定是1182字节了。现在,只要从原始文件中跳过1182字节后复制908字节,替换掉fread($O000O0O00,908)
,然后把eval换成echo就可以了。
不过,也许是因为我得到文件已经被别人修改过,跳过1182字节后复制的数据无法正确解码。我尝试复制了那27KB数据开头的908字节,才看到了正确的结果。

那段判断域名的代码已经注释掉了。有用的就是最后一段:
# 先前已经打开文件,定位到27KB数据开头,读取908字节
$OO00O00O0=str_replace(
'__FILE__',
"'".$OOO0O0O00."'",

);//读取26408字节,根据代码表替换字符,base64解码,把__FILE__替换为真正的当前文件名
fclose($O000O0O00);//关闭文件
eval($OO00O00O0);//执行代码
处理方法就很明显了,从原始文件的27KB数据开头起,跳过908字节,复制26408字节,替换掉fread($O000O0O00,26408)
,eval换成echo。前面那次解码使用的代码也需要删除,但是$OOO0O0O00=__FILE__;
这句要留着,因为str_replace里用到了这个变量。

看来是某分类信息发布程序的一个页面。PHP是一个自由、开源的世界,将代码弄成这样,影响执行效率、不便于修改,何必呢?
好吧,我已经写了两篇有关PHP解码的文章了,最近不会再有更多的相关文章了。如果你遇到了一段被编码的PHP脚本,最好的处理办法就是不使用这个程序。对一切有违自由、开源精神的PHP程序,请各位自觉抵制。
2010-05-06更新:本文介绍的PHP代码,是用 微盾PHP脚本加密专家 加密产生了。我制作了一个PHP解密工具,可以解密PHP脚本,包括本文提到的脚本,欢迎试用。
