| This data is incomplete. You must provide all file contents. Right now there is only step1 and step 2 decoders, but actual encoded main code is missing! |

First of all - do not ever do "eval()" with untrusted data! Just echo it out or write to file for further analyze.
Now, step 1 decoder:
<?php
error_reporting(E_ALL);
$x = gzuncompress(base64_decode('eNplj1dvwjAAhP9MpNgiCJMFUZQH9sbs9VJlOAOysDMgv76gVm2l6u7pdPdJx2GEEH4JGW6SkhhwGOOvQOCpxUO99IOQgHqdw+/i29D1SMYA9zMVmkiUof4vlpGmQv1F/F4aXpXHdhKllDAGLJMRVf5wiJ04BLCMZhS4lJjOX4QiqVDg74NaT0xKzB5mF1V+sBydVkdNKmZUvqX9q3IZW20nm+d2PDx0mm4YNZ7rnbfdkPNkul+0VIMX+E631x8MR+PJdDZfLPFqvdnu9ofj6XwxLdshrucH11sYxUl6pyzLi/LxrFBTlGRFbbW1WoOHEOqkMEPwewjqn85iXyI='));
file_put_contents('./step1.txt', $x);
die("ok");
?>
And you will see:
$O000O0O00=fopen($OOO0O0O00,'rb');
while(--$O00O00O00)fgets($O000O0O00,1024);
fgets($O000O0O00,4096);
$OO00O00O0=gzuncompress(base64_decode(strtr(fread($O000O0O00,536),'qE+C2owOsxaB0zhiNGXPW93vKr4kpDj5ZHb8dtLucnFVA1flm/yQTgSReYIJUM76=','ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/')));
eval($OO00O00O0);
So as seen above, you must have one more line in your php file. And you have not posted it ...
Look at your original encoded php file - there should be some bas64 encoded data after closing "?>" tag! |
