does not recognize the @ symbol, so it is changed to the echo off CLS, and the VBS can parse to call a function called echo () with the argument off CLS, i.e. two string off and CLS addition Well, next, you can run the VBS script, and the efficiency is as high as the real VBS! The advantage of this code is that you do not have to generate temporary files. In fact, the use of echo or more or find to generate temporary VBS is a waste of system resources, with the code I wrote, it completely e

ARP spoofing is achieved by forging IP addresses and MAC addresses, which can generate a large amount of ARP traffic in the network to block the network, attackers can change the IP-MAC entries in the ARP cache of the target host as long as they continuously generate forged ARP response packets, resulting in network interruptions or man-in-the-middle attacks. This article introduces four methods to defend against ARP attacks by using self-made batch
