Ettercap is a suite for man in the middle attacks on LAN (local area network ). It features sniffing of live connections, content filtering on the fly and many other interesting tricks.It supports active and passive dissection of many protocols (even ciphered ones) and includes many feature for network and host analysis. In this tutorial i will explain how to sniff (user names,passwords) in LAN using Ettercap
Man In The Middle Attack
The man-in-the-middle attack (also known as a bucket-brigade attack and abbreviated MITM) is a form of active eavesdropping in which the attacker makes independent connections with the victims and relays messages between them, making them believe that they are talking directly to each other over a private connection when in fact the entire conversation is controlled by the attacker.
There are several kinds man in the middle attacks that we can perform, But in this tutorial we will see attacks based on the ARP protocol
ARP Poisoning
Address Resolution Protocol (ARP) spoofing, also known as ARP flooding, ARP poisoning or ARP Poison Routing (APR), is a technique used to attack an Ethernet wired or wireless network. ARP Spoofing may allow an attacker to sniff data frames on a local area network (LAN).
