One of the easiest ways to manipulate the direction of the traffic remotely is to play with DNS records. Each operating system contains a host file in order to statically map hostnames to specific IP addresses. The host file is a plain text file, which can be easily rewritten as long as we have admin privileges. For now, let's have a quick look at the host file in the Windows operating system.

Then, after at least one space, the name follows. You will also see that each record's that the IP address begins first, then we get the hostname.

- Open Wireshark on our target machine and start the capture.
- Filter on the...
