VII 在防火墙测试中应用

简介

  VII is a c script based tool which can send any kinds of packets. It support random protocol/port/ip and so on and can practice as udp/tcp/.. flood/overlap attack tools.

特点

 

1. 基于脚本

    采用通用的c语言编译器。

 

2. 基于winpcap

 

示例

这是一段发送UDP flood 攻击的脚本，每个UDP包源端口不变， ID也不变，目标端口随机。

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <mytcp.h>





void agreeLicense(){};



void data(myDATA* d,int n){

unsigned char pkt6[] = {

0x00, 0x11, 0x43, 0x4c, 0x82, 0xad, 0x00, 0x0c, 

0x29, 0x7a, 0xa3, 0x4f, 0x08, 0x00, 0x45, 0x00,

0xbf, 0x57, 0x0a, 0x00, 0x33, 0x87, 0x0a, 0x00, 

0x33, 0xf2, 0x80, 0x00, 0xdb, 0xf4, 0x00, 0x09,

pktcpy(d,pkt6+42,sizeof(pkt6)-42);

}



void Eth(myET_HEADER* eth,int n){

	//set dst mac 

	mac(eth->eh_dst,"00-0C-29-D2-9D-B4");

	//set src mac 

	mac(eth->eh_src,"00-24-E8-32-95-81");

}



void IP(myIP_HEADER* iph,int n){

	iph->sourceIP = inet_addr( "--.--.--.--" ); 

	iph->destIP = inet_addr( "--.--.--.--" );

	iph->total_len = 0x1d00;

	iph->frag_and_flags = 0x0040;

	iph->ident = 0;

	iph->proto = 0x11;

	iph->ttl = 64;

}



void UDP(myUDP_HEADER* uph,int n){

        //int srcport = rand()*65535;

        int dstport = rand()*65535; 

	uph->uh_sport = 11<<8|11>>8; 

	uph->uh_dport = dstport<<8|dstport>>8;

	uph->uh_len = 0x0900;

	//uph->uh_sum = 0;

}





int mymain(void){

	readLicense();

	void (*func)(int,int);

	func=loadEngine("UDP2");

	func(2,990000);

}





另一个示例，这个示例发送ICMP  request请求； 通过抓包可以接收到ICMP reply

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <mytcp.h>





//if you are agree with license, add function "void agreeLicense(){};"

void agreeLicense(){};

	mac(eth->eh_src,"--.--.--.--");

}



void IP(myIP_HEADER* iph,int n){
