Decoding the PHP file when there is no clue about the type of encoder

Question

I am trying to decrypt this PHP file(See the pastpin link given below) for the past one week using many tools around web but nothing worked. After then i found out the ,even i am acessing the tools which is really not build for the particular decryption type.Automated engine fails,Human always wins! I am here for the help of fellow members to help me out to decrypt this script with their stuff.

Here is the link below of the code snippet
http://pastebin.com/PveEgFY5

Please help me out to understand the type of encoder which was used by the script and to decrypt the code to find the source code.

Thanks in advance.

Use base64_decode(): http://php.net/manual/en/function.base64-decode.php

For example, this:

eval($OOO0000O0('JE8wMDBPME8wMD0kT09...hbCgkT08wME8wME8wKTs='));

equals to:

eval($OOO0000O0(

    $O000O0O00 = $OOO000O00($OOO0O0O00,'rb');
    $O0O00OO00($O000O0O00,0x4fa);
    $OO00O00O0 = $OOO0000O0($OOO00000O($O0O00OO00($O000O0O00, 0x368), '3C4hHR7yEoKBnvWimqfuSGt56bd2DkYzMjL+rVNZslFxgUIpX9aPT/cOewQJ081A=', 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'));
    eval($OO00O00O0);

));

The string 3C4hHR7yEoKBnvWimqfuSGt56bd2DkYzMjL+rVNZslFxgUIpX9aPT/cOewQJ081A= converts into binary data, it could be part of an image, music file or something else... the other string:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/

is probably the key to decode the string: $OOO0000O0=$OOO000000{4}.$OOO000000{9}.$OOO000000{3}... where each number as example $OOO000000{4} is a letter of the previous string, in this case, starting from zero it should be E, but decode the rest of the code to better understand what it does.

hi,

Just want to add something..

This $OOO000000 is equal to fg6sbehpra4co_tnd..

The strings are encoded in such a manner that O is equavalent to 1 where as...

$OOO0000O0 is formulated dependent and referenced to 11100010

which is equavalent to 226 in human numbers..and this $OOO0000O0=$OOO000000{4} is actually equal to 228 in human numbers but it is 11100100 computer's own understanding OR it is just a mere E4 if it is expressed as HEX.

I was wrong about this string:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/

It is used in a second instance. Veedoo suggestion is correct, with that string the first part:

$OOO000000 = urldecode('%66%67%36%73%62%65%68%70%72%61%34%63%6f%5f%74%6e%64'); # fg6sbehpra4co_tnd
$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};

$OOO000O00 = $OOO000000{0}.$OOO000000{14};
$O0O000O0O = $OOO000O00.$OOO000000{11};
$O0O000O00 = $OOO000O00.$OOO000000{3};
$O0O00OO00 = $OOO000000{0}.$OOO000000{8}.$OOO000000{5}.$OOO000000{9}.$OOO000000{16};
$OOO00000O = $OOO000000{3}.$OOO000000{14}.$OOO000000{8}.$OOO000000{14}.$OOO000000{8};

$OOO0O0O00 = __FILE__; # current file name
$OO00O0000 = 0x9a0;

can be shown by echoing these variables:

echo $OOO0000O0.PHP_EOL; # base64_decode
echo $OOO00000O.PHP_EOL; # strtr
echo $O0O00OO00.PHP_EOL; # fread
echo $OOO0000O0.PHP_EOL; # ft
echo $O0O000O0O.PHP_EOL; # ftc
echo $O0O000O00.PHP_EOL; # fts

which outputs few PHP functions and a bunch of user defined function names(?). It seems the code is not complete, some variable names are missing and the function ft() is not defined. Anyway the part decoded in the first post becomes:

$O000O0O00 = $OOO000O00($OOO0O0O00,'rb'); # ft(__FILE__,'rb'); which probably is fopen()
$O0O00OO00($O000O0O00,0x4fa);             # another function: fread, 0x4fa converts to 1274

Which translates to:

$fp = fopen(__FILE__,'rb');
fread($fp,0x4fa);

next step:

$OO00O00O0 = $OOO0000O0($OOO00000O($O0O00OO00($O000O0O00, 0x368), '3C4hHR7yEoKBnvWimqfuSGt56bd2DkYzMjL+rVNZslFxgUIpX9aPT/cOewQJ081A=', 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'));

becomes:

$OO00O00O0 = base64_decode( strtr( fread($fp,0x368), '3C4hHR7yEoKBnvWimqfuSGt56bd2DkYzMjL+rVNZslFxgUIpX9aPT/cOewQJ081A=',  'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'));

after that, there is an eval($OO00O00O0) which means execute the string as code, by echoing $OO00O00O0 we get this string:

while(
    !preg_match(
        '#^((.*\.)?uimg\.info)$#i',
        $O000OO00O = (isset($_SERVER['SERVER_NAME']) ? $_SERVER['SERVER_NAME'] : (isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : (isset($HTTP_SERVER_VARS['SERVER_NAME']) ? $HTTP_SERVER_VARS['SERVER_NAME'] : (isset($HTTP_SERVER_VARS['HTTP_HOST']) ? $HTTP_SERVER_VARS['HTTP_HOST'] : ''))))))
die($O000OO00O.'

which in other form is this:

if(isset($_SERVER['SERVER_NAME']))
{
    $O000OO00O = $_SERVER['SERVER_NAME'];
}
elseif(isset($_SERVER['HTTP_HOST']))
{
    $O000OO00O = $_SERVER['HTTP_HOST'];
}
elseif($HTTP_SERVER_VARS['SERVER_NAME']))
{
    $O000OO00O = $HTTP_SERVER_VARS['SERVER_NAME'];
}
elseif(isset($HTTP_SERVER_VARS['HTTP_HOST']))
{
    $O000OO00O = $HTTP_SERVER_VARS['HTTP_HOST'];
}
else
{
    $O000OO00O = '';
}

while(!preg_match('#^((.*\.)?uimg\.info)$#i',$O000OO00O)

die($O000OO00O.'

It is not complete, but this part of the script is trying to get information about the server in which is executed.

The last part encodes open and fge, the first is not complete, it could be fopen which is missing and was part of the undefined function ft.

Now: I tried to perform $OO00O00O0 function on the last part of the code, which is outside PHP tags but I don't get anything but random characters, maybe I'm missing something. You can try it by yourself: http://pastebin.com/SyMD9uMZ

Can I ask where did you found this code? It was embedded is some binary file? Bye.
