What is a Man-in-the-Middle Attack?
In this video, Chuck Keith covers man in the middle attacks, specifically those prepared with ARP spoofing. He will define what a man in the middle attack is, how it works, and then explain how ARP spoofing can be used to substantially increase the potency of a typical MITM attack.
The Address Resolution Protocol, or ARP, is used to find the layer 2 address of the device associated with a given IP address. When someone wants to communicate with the rest of the internet, they must go through a default gateway — their router.
The router’s IP address is easy to discover, but you also need the MAC address. If the user doesn’t already have the MAC address stored in his ARP cache, he’ll use an ARP broadcast to send a request to everyone on his network, asking for the address.
The router is programmed to respond and provide its MAC address, but if someone is able to get in the middle and spoof the ARP, he can gain access to the user’s computer. Chuck will explain how these work and how to defend against them.
