EMLOG拓展|EMLOG简易防CC攻击代码

EMLOG没有自己的防护措施，找了一款PHP代码修改成EMLOG的。也就凑活用吧。



源代码

<?php
//代理IP直接退出
empty($_SERVER['HTTP_VIA']) or exit('Access Denied');
//防止快速刷新
session_start();
$seconds = '3'; //时间段[秒]
$refresh = '5'; //刷新次数
//设置监控变量
$cur_time = time();
if(isset($_SESSION['last_time'])){
$_SESSION['refresh_times'] += 1;
}else{
$_SESSION['refresh_times'] = 1;
$_SESSION['last_time'] = $cur_time;
}
//处理监控结果
if($cur_time - $_SESSION['last_time'] < $seconds){
if($_SESSION['refresh_times'] >= $refresh){
//跳转至攻击者服务器地址
header(sprintf('Location:%s', 'http://127.0.0.1'));
exit('Access Denied');
}
}else{
$_SESSION['refresh_times'] = 0;
$_SESSION['last_time'] = $cur_time;
}
?>

EMLOG版



将下面代码插入在module.php文件内

<?php
function lmink_cc(){
//代理IP直接退出
empty($_SERVER['HTTP_VIA']) or exit('Access Denied');
//防止快速刷新
session_start();
$seconds = '3'; //时间段[秒]
$refresh = '5'; //刷新次数
//设置监控变量
$cur_time = time();
if(isset($_SESSION['last_time'])){
$_SESSION['refresh_times'] += 1;
}else{
$_SESSION['refresh_times'] = 1;
$_SESSION['last_time'] = $cur_time;
}
//处理监控结果
if($cur_time - $_SESSION['last_time'] < $seconds){
if($_SESSION['refresh_times'] >= $refresh){
//跳转至攻击者服务器地址
header(sprintf('Location:%s', 'http://127.0.0.1'));
exit('Access Denied');
}
}else{
$_SESSION['refresh_times'] = 0;
$_SESSION['last_time'] = $cur_time;
}
}
?>

然后在header.php文件 <html>前插入<?php echo lmink_cc(); ?>



大功告成，快去试试吧~
