A.R.P spoofing

A.R.P=> ADDRESS RESOLUTION PROTOCOL

arp spoofing

arp protocol used in MITM (man in the middle) attacks where attacker attack the victim under local  area network (L.A.N)  it requires the mac address of victims machine as well as I.P address of victims machine for a.r.p spoofing

attacker manipulate between the I.P of victim and router when the request sent by the victim it passes through attacker first then it passes through the router hence attacker able to see all the requests and responses sent by the victim and also be able to change and modify it because whole traffic is going through under the surveillance of attacker

in this process attacker monitoring, all the activities have done by the victim 

in this process logically victim's machine thinks that all the responses and request getting directly through the router which is not happening and the same procedure happens with a router it also thinks all the responses are delivered directly to specific machine or computer in the whole process attacker tricks both router and victim and get all (information and data) 

source of the internet will change according to the situation whether it will be the router or any device which connects the victim to the internet whenever method will remain the same and these known as (arp poisoning)

• important_note=> this article gives the only simplified overview of arp poisoning and how its work the only purpose of this article is to give a simple understanding of arp for more information you can search over the internet for deep knowledge
  
  
  

metasploit

Metasploit 

penetration testing allows you to answer the question, "how can someone with malicious  intent mess with my network" using pen-testing tools, white hats, and devsec professionals can probe networks and applications for flaws and variabilities at any point along the production and deployment process of hacking the system one such penetration testing aid is the Metasploit project

this ruby_based open_sourse framework allows testing via command line alteration or GUI via command-line alternative or GUI it also be extended through coding to act as an add as that supports multiple languages
