hacking trick

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), .

Man In The Middle Attack Using Ettercap

1. First download Ettercap From  Here

2. After installation open  Ettercap , select sniff mode and select your network interface as shown

3. Now scan for hosts in your sub net  by going to Hosts ---> scan for hosts

4. Now open host list from hosts tab and select the IP address of the victim as target 1 and IP address of the router as target 2

5. Now start ARP poisoning by going to mitm ---> ARP Poisoning 

6. Finally start the sniffer by going to start ---> start sniffing . Now if the victim logs into gmail , face book yahoo mail...etc .we will get his user name and password  

Hope you Enjoyed the article, In my coming posts i will be writing about the countermeasures that you can take against ARP poisoning , MITM ..etc .Till then have a nice time
