Python ARP扫描与欺骗实现全程详解
ARP欺骗又称ARP毒化或ARP攻击,是针对以太网地址解析协议ARP的一种攻击技术,通过欺骗局域网内访问者PC的网关MAC地址,使访问者PC错以为攻击者更改后的MAC地址是网关的MAC,导致网络不通。此种攻击可让攻击者获取局域网上的数据包甚至可篡改数据包,且可让网络上特定计算机或所有计算机无法正常连线。
实现ARP扫描: 运用Scapy工具包,开发一款ARP扫描工具,扫描网段内所有的在线主机并显示其MAC地址。
from scapy.all import * from optparse import OptionParser import threading def parse_ip(targets): _split = targets.split('-') first_ip = _split[0] ip_split = first_ip.split('.') ipv4 = range(int(ip_split[3]),int(_split[1])+1) addr = [ ip_split[0]+'.'+ip_split[1]+'.'+ip_split[2]+'.'+str(p) for p in ipv4 ] return addr def arp_scan(address): try: ret = sr1(ARP(pdst=address),timeout=5,verbose=False) if ret: if ret.haslayer('ARP') and ret.fields['op'] == 2: print('[+] IP地址: {} => MAC地址:{}'.format(ret.fields['psrc'],ret.fields['hwsrc'])) except Exception: exit(1) def Banner(): print(" _ ____ _ _ ") print(" | | _ _/ ___|| |__ __ _ _ __| | __") print(" | | | | | \___ \| '_ \ / _` | '__| |/ /") print(" | |__| |_| |___) | | | | (_| | | | < ") print(" |_____\__, |____/|_| |_|\__,_|_| |_|\_\\") print(" |___/ \n") print("E-Mail: me@lyshark.com\n") if __name__ == "__main__": Banner() parser = OptionParser() parser.add_option("-a","--addr",dest="address",help="--> input 192.168.1.0-100") (options,args) = parser.parse_args() if options.address: addr_list = parse_ip(options.address) for item in addr_list: threads = [] t = threading.Thread(target=arp_scan,args=(item,)) threads.append(t) t.start() for item in threads: item.join() else: parser.print_help()
执行扫描如下:
实现ARP欺骗: 通过ARP协议扫描网络中在线主机,并能够指定IP地址断掉网络.

开启转发功能,开始运行里面输入regedit
打开注册表编辑器,在注册表定位下面注册表项。

实现DNS欺骗: 网上其他人的一种实现方法,代码如下,只不过我们只做了ARP骗,而在该欺骗基础上可以加强为DNS欺骗。
