So the target needs to be on the same local area network for our attacks to work. These attacks are really helpful when you are performing internal penetration tests. The only way to make them work remotely is by compromising a host remotely and then using that compromised host to sniff traffic on its local network, but this is not discussed in this chapter as all this is a part of ...
