ARP Spoofing


ARP

Address Resolution Protocol (ARP) is a communication protocol used for resolving IP address to MAC address. Understanding it in simple form,let us assume a source computer wants to send some data to a target computer through LAN.But the source only knows the IP address of the target,not the MAC address.So it is unable to send the data.And here where ARP works!ARP helps here to get the MAC address of the target IP address.

ARP Spoofing

In simpler terms,ARP spoofing is the technique of redirecting the network traffic to the attacker by faking the IP address.In this attack,attackers links their MAC address with the IP address of a legitimate computer or server on the network.With the help of this attack, attackers can intercept, modify or even stop data which is in transit.It can only occur on LAN that utilize the ARP.

Usually attackers perform this attack by following steps:

Practical tutorial for this attack will be posted in next article soon.
