This tutorial will explore the topics of ARP related attacks, specifically Man-in-the-Middle (MITM) and Denial of Service (DOS) attacks.

Attacks?

The information contained in this tutorial can be very harmful to a network. This is NOT something you should try in the wild, that is on a network that you do not own. For our purposes we've set up a test network to experiment with. We feel that the best way to learn about the tools and methodologies hackers use is to use them ourselves. Remember that this information is presented for academic reasons and use of it on a network that you do not own could be grounds for prosecution and incarceration.

Man in the Middle (MITM)

The first attack we will look at is the most useful of the first two we will look at. It's called a Man-in-the-Middle attack or MITM for short. As the name implies the attacker places himself in the middle of select or all communications on the LAN. This allows his computer to dissect incoming packets for information such as passwords.

Denial of Service (DoS)

The second attack we will look at is useful for keeping Hosts isolated from the LAN in order to masquerade as them, or to stop a LAN from communicating altogether.
