This article is about how to implement batch processing to prevent arp spoofing and automatically bind gateways. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Put the following code. Save as doarp.bat and add to autorun.

The code is as follows:

@ echo OFF

If% ~ n0==arp exit

If% ~ n0==Arp exit

If% ~ n0==ARP exit

Echo is getting native information.

: IP

FOR / f "skip=13 tokens=15 usebackq"% I in (`ipconfig / all`) do Set IP=%%i & & GOTO MAC

: MAC

Echo IP:%IP%

FOR / f "skip=13 tokens=12 usebackq"% I in (`ipconfig / all`) do Set MAC=%%i & & GOTO GateIP

: GateIP

Echo MAC:%MAC%

Arp-s% IP%% MAC%

Echo is getting gateway information.

FOR / f "skip=17 tokens=13 usebackq"% I in (`ipconfig / all`) do Set GateIP=%%i & & GOTO GateMac

: GateMac

Echo IP:%GateIP%

FOR / f "skip=3 tokens=2 usebackq"% I in (`arp-a% GateIP% `) do Set GateMAC=%%i & & GOTO Start

: Start

Echo MAC:%GateMAC%

Arp-d

Arp-s% GateIP%% GateMAC%

Echo operation completed!

Exit

A detailed description is attached below:

This script is an anti-ARP attack. Add native ip, mac and gateway ip and mac programs manually

If% ~ n0==arp exit

If% ~ n0==Arp exit

If% ~ n0==ARP exit / / decide to quit if it has been infected

Echo is getting native information.

: IP

FOR / f "skip=13 tokens=15 usebackq"% I in (`ipconfig / all`) do Set IP=%%i & & GOTO MAC

: MAC

Echo IP:%IP%

FOR / f "skip=13 tokens=12 usebackq"% I in (`ipconfig / all`) do Set MAC=%%i & & GOTO GateIP

: GateIP

Echo MAC:%MAC%

Arp-s% IP%% MAC%

/ / as prompted above, get native IP and mac. Arp-s% IP%% MAC% adds native ip/mac to the corresponding table of native ip/mac.

Echo is getting gateway information.

FOR / f "skip=17 tokens=13 usebackq"% I in (`ipconfig / all`) do Set GateIP=%%i & & GOTO GateMac

: GateMac

Echo IP:%GateIP%

FOR / f "skip=3 tokens=2 usebackq"% I in (`arp-a% GateIP% `) do Set GateMAC=%%i & & GOTO Start

: Start

Echo MAC:%GateMAC%

Arp-d

Arp-s% GateIP%% GateMAC%

/ / this is the ip/mac address of the gateway, where arp-s% GateIP%% GateMAC% loads the ip and mac of the gateway into the local corresponding table.
