利用四种自制批处理文件防御ARP攻击

@ECHO OFF

for /f "tokens=2 delims=[]=" %%i in (nbtstat -a %COMPUTERNAME%) do call set local=!local!%%i
for /f "tokens=3" %%i in (netstat -r^|find " 0.0.0.0") do set gm=%%i
for /f "tokens=1,2" %%i in (arp -a %gm%^|find /i /v "inter") do set gate=%%i %%j
arp -s %gate%
arp -s %local%
arp -s 网关IP 网关MAC

@echo off
:::::::::::::清除所有的ARP缓存
arp -d

for /f "tokens=13" %%I in (find "Default Gateway" ipconfig.txt) do set GatewayIP=%%I
::::::::::::ING三次内网网关
ping %GatewayIP% -n 3
:::::::::::::读取与网关arp缓存
arp -a|find "%GatewayIP%">arp.txt
:::::::::::::读取网关MAC并绑定
for /f "tokens=1,2" %%I in (find "%GatewayIP%" arp.txt) do if %%I==%GatewayIP% arp -s %%I %%J

arp -s %ip% %mac%
:::::::::::::删除所有的临时文件
