All Rights Reserved. The purpose of a nuke is to break your connection with the internet. To nuke you, your attacker uses a nuke program to take advantage of certain operating system bugs in your Windows95 operating system. Because of bugs in the Win95 system, this has the effect of forcing your computer to shut down the port under attack. Ports are basically electronic gates in your computer where data goes out and comes in.
Different ports have different numbers and they are assigned different functions.
If you are using FTP, for example, your computer is using Port 21. If you are using Telnet your computer is operating Port 23. If you use your web browser, you are using Port 8080. This port is always open when you are online. When you have a port open, it is vulnerable to attack.
